This function is supposed to open a file stream and copy the text into an integer array to be used for a map key. Here is the contents of the file. I am getting the decimal value stored in the array and I just cannot figure out how to correct the problem. I tried casting, atoi(), and other stuff, but I am still not figuring it out.

ahnoldschwarz said he wants to be a game designer, not a game programmer. I would start out by learning the basic concepts of programming, i.e. variables, control statements, and other concepts that are apparent in just about any language. I would then go on to learn a scripting language such as Python, Ruby, or Lua.

Game designers generally do not do a whole lot of programming in most projects. When they do write some code it is usually writing up scripts for designing a game level or things of that nature.

If you want to get into game design you should build your skills in the area of game documentation and practice making clear, informative, and practical documentation. Work on building any kind of prototype you can to get a feel for the things that may work well in your design and things that may need to be changed or eliminated. I don't understand why everyone is suggesting all of these different programming languages to someone who desires to get into game design.

while((board.getgXPos() != board.getXPos()) && (board.getgYPos() != board.getYPos()))
{
system("cls");
board.printBoard();
board.moveBall();
}

I would like this while statement to continue repeating until both gxPos equals XPos & gyPos equals YPos.

I can't seem to figure out why the statement exits if either both x's are the same or if both y's are the same.

My fogMap array was printing fine then I integrated the menu into it and now I am getting an error. When I select the option to play the game my mapFog array outputs, but after that the program breaks and says "No symbols are loaded for any call stack frame. The source code cannot be displayed" What does that mean?

Also, by that description, what would I be looking for in the disassembly?

I am trying to print a two-dimensional array to the screen. My algorithm probably isn't correct but I am having trouble even getting the process to work.

on the call I get ----error A2206: missing operator in expression
This line add ebx,tmpRowSize * rowIndex I get ------error A2026: constant expected

Thanks in advance for any input

I am stuck on problem 7 that is outlined clearly. I am trying to create a process that changes all of the non-prime number elements of a 65,000 element array to 1. Then I would like to verify that array was marked correctly so that only prime numbers have 0's at their location in the array. The displayArray process should display 1,3,5,7,11,13 etc. up to 65,000.

There is an include file also
Thanks for your help

The problem was that I was trying to use functions in the engine before I created the engine itself. I solved the problem by moving the new Engine( &setup) above the three functions I was testing.

I am trying to create a set of functions to allow the user to output a string to a file name EngineLog.txt

It compiles fine, but I get an Unhandled exception at 0x00444c36 in Test.exe: 0xC0000005: Access violation writing location 0x0000000d. This occurs in the EnableLogging() function.

Hi, I am trying to get a cat walking back and forth between the screen using a left and right tileset of bitmaps. Also, I am supposed to be able to control two caveman sprites that appear to walk left and right as you press the left and right keys.

The first iterator isn't getting assigned the correct number. instead of size - 1, it is being assigned to -842150451. Then obviously that number is being copied to the new stack.

    node* currNode = stackTop;
    int* stackContents = new int[stackSize()];
    otherStack.initialize();

    for( int i = size - 1; i < 0; i--)

        assert( currNode != NULL );
        stackContents[i] = currNode->number;
        currNode = currNode->link;
     }

     for( int j = size -1; j >= 0; j--)
        otherStack.push( stackContents[j] );

} //end copyStack

The result should be two identical stacks. It only outputs blank lines. I

I am writing a class character for an assignment. The class relates to a role playing game. I am getting an error which I don't understand. This error occurs in the default constructor of the implementation file. The dynamic help says that I created an object without creating a pointer to that object.

Can anyone explain why I am not getting any output from this code

yeah but if the strings dont compare then the found = true; statement isn't executed and found should be false still

How do I search through an array of objects to see if a player name is in the array of objects? The code I have in main I know is incorrect cause I get "Player is in database!" whether or not the player is in the database and it obviously prints six times.

bool playerType::searchPlayer(string searchFirst, string searchLast)
{
    bool found = false;
            if (getFirstName() == searchFirst && getLastName() == searchLast)
            {
                found = true;
            }
            
        if (found = true)
            cout << "Player is in database! ";
        else
            return false;
}

Here is the code in main that I have in a switch statement to access the search function

int n;
        cout << "Enter the first and last name of the player to search for." << endl;
        cin >> fname >> lname;
        for (n = 0; n < 6; n++)
            player[n].searchPlayer(fname, lname);
      break;

Well I would be searching for two different strings

IF I have seven objects of playerType player, player1, player2, player3...etc and I want to search to see if there is a certain player in these objects, how would I do that. I know my code isnt complete and is quite off but if someone could take my blindfold off and point in the right direction, I would appreciate it.

bool playerType::searchPlayer(string searchFirst, string searchLast)
{
    int i;
    bool found = false;
        for (i = 0; i < 6; i++)
            if (name.getFirstName == searchFirst && name.getLastName == searchLast)
            {
                found = true;
                break;
            }
            
        if (found)
            cout << "Player is in database! ";
        else
            return false;
}

So im new to vectors and I'm trying to create an addTeam function, The ultimate outcome should be an object with a division name, 5 teams in a division and 5 players on each team. Here is what I have so far. Please advise on whether I am on the right track or not.

Getting these errors

team.h(22) : error C2059: syntax error : 'constant'
team.cpp(9) : error C2373: 'team::addTeam' : redefinition; different type modifiers

{
public:
    void printTeam(); const

    void addTeam(string divName, vector<string> name);    //Line 17
        //Function to store a team with a division name and player names
        //Postcondition:    divisionName = divName; firstName = fName; lastName = lName

private:
    vector<string> playerName(5);       //Line 22
    string divisionName;

};

#endif

#include "team.h"
#include <string>
#include <iostream>
#include <vector>


void team::addTeam(string divName, vector<string> name)
{
    divisionName = divName;
    playerName.push_back(name);
}

So if I were to only write one team class and used a menu that the user chose to (C)reate a team. would I use a local static variable to create a team object within the switch where a new object could be create incrementally. i.e.

switch (x)
       case 'c' case 'C'
       static int t = 1;
       team team[t]  //where this is a created object
       ++t;
       team1.createTeam();
      break;

Wouldn't it be better to simply write one team class and just instantiate 5 teams from that one class? What would be the benifit to the 5 different team classes?

I am writing a program which has these require ments
1.Program must be command-line based and interactive, allowing the user to control its operation by entering commands.
2. ability to accept new data
3. ability to search for specific previously entered data
4. ability to save data to a file
5. ability to retrieve data from a file
6. at least 5 classes
7. must show inheritance and polymorphism
8. must read and write a file

I am writing a program to store a basketball league. I have two classes already called personType and PlayerType, one of which is inherited from the other.

I am now brainstorming for the part of my program which will store 3 different divisions. Each division will have 5 teams and each team will have 5 players.

I was going to have the division class be the base class and team class will be derived from division and player's derived from team.

Would it be best to have division object which have a string for the division name, an array for the team names and each team would have an array of players?

I am coding a class project where I will have a basketball league. The league will include 3 divisions and each division will have 5 teams. Each team will have a number of players and one coach. I must have 5 seperate classes. I already have two classes called person and player and will also add coach. I think my next two classes will be division and team. My question is how should I implement these two classes? I must be able to add players and a coach to a team and add teams to a division. Should I use arrays for only 3 divisions and for the teams? I'm just a little confused on how to set everything up and how everything will interact.

Well I used the jump function that you wrote and I tried to add the loop that prints the top half of the diamond where you have the going up code, then I put the code for the bottom half where you have the going down in inches code. No matter where I put the code for the bottom half of the diamond it doesn't print.

I tried it after the recursive call, I tried it before the recursive call, I tried it with a else after the recursive call. Every time I just get the first half of the diamond. I don't really understand where to put the loop for the bottom half so it will execute.

Well that brings a whole new light to the subject. I didn't understand that the function stepped back out. I've been messing around with my code and I can't figure out where to put the loop to print the bottom half. I attempted to use your example code but that didn't seem to work for me. Any more hints for the newb?

I don't understand how that works. The Jump (n + 1) recursively calls Jump up to n =8 then why does going down keep getting called? there is no recursive call there

I made a mistake here, I used a static int x in the topDiamond function but this doesn't work obviously. How do use a variable in a recursive function that is only static within the function?

So here is what I have so far. This Recursive function prints the top half of the diamond. For the bottom half should I create another recursive function to print the bottom half of the diamond and call it indirectly by the topDiamond function?

#include <iomanip>
#include <iostream>
#include "diamond.h"

using namespace std;

int diamond::botDiamond(int num)
{
    return 0;
}

int diamond::topDiamond(int num)
{
    static int x = 1;
        if (num == 0) return 0;
    
        cout << setw(num + 1);
        for (int i = 0; i < x; i++)
            cout << "* ";
        x++;
            cout << endl;
        if (num == 1)
        return botDiamond(num);

        return num = topDiamond(--num);
}

        diamond::diamond(int num)
        {
            if (num <= 0)
                cout << "Width of diamond must be greater than 0.";
            rows = num;
        }

        diamond::diamond()
        {
            rows = 10;
        }

if (month < 0 || month > 12 || day < 0 || day >31 || year > 1900 ||| year < 2099 )

I believe you have 3 mistakes here in this line

So I was going to write a function to print "* " one astrick and a space and then depending on the parameter of the recursive function, which is an int to identify the number of astricks in the largest row. It would call the function to print "* " in the body of the recursive function depending on that parameter. If anyone can provide any more help I would greatful as I am still struggling on how to accomplish this task.

I was given an assignment to write a recursive function to print a diamond comprised of astrisks (less the dashes) such as:

---*
--* *
-* * *
* * * *
-* * *
--* *
---*

The parameter is the number of astricks in the largest row. I have written the function which works fine but, I am lost when it comes to converting this function to a recursive function. Any help would be appreciated.

#include <iostream>
#include <iomanip>
using namespace std;



void diamond(int row);

int main()
{
    diamond(12);
}

void diamond(int row)
{

int spaces = row * 2;



    for (int i = 0; i <= row + 1; i++)
    {
        cout << setw(spaces);
        for (int j = 0 ; j < i - 1; j++)
            cout << "* ";
            cout << endl;
            --spaces;
    }    
         for (int i = 0; i < row; i++)
        {
            cout << setw(spaces+2);
            for (int j = row - 1 ; j > i; j--)
            cout << "* ";
            cout << endl;
            ++spaces;
        }
}

You get cheese.

Hey thanks that was the problem. Now my inherited print() function works just fine. The text I am using defines constructors the way I have coded it so I think I will just stick with that way for now.

Are there any benefits to including the constructor in the declaration like that?

I have implemented inheritance and in the print function for class playertype I have called the print function from personType. When I call the playerType fucntion print() with a playerType object only the playerType variables are printed and not the personType variable firstName and lastName.

#ifndef H_personType

       //in the form firstName lastName.
  
    void setName(string first, string last);
       //Function to set firstName and lastName according 
       //to the parameters.
       //Postcondition: firstName = first; lastName = last

    string getFirstName() const;
       //Function to return the first name.
       //Postcondition: The value of the firstName is returned.

    string getLastName() const;
       //Function to return the last name.
       //Postcondition: The value of the lastName is returned.

    personType(string first = "", string last = "");
       //constructor

When overloading the insertion and extraction operators they must be nonmember functions because cout and cin are not objects of the class

Another gentleman said he input my code into .net 2003 and it compiled fine, he then converted it to VS 2005 and still compiled ok. He also stated that there were no significant changes in the conversion. I am still seeking input on this problem, so if anyone can help I would greatly appreciate it.

That is the exact same final I have in my C++ programming class at Westwood Online

Well I dont understand that I have the exact same code in VS 05 and I get the dern errors

I use Visual studio 2005.

Thats how my textbook coded this particular constructor. The program was working fine until I added the two overloaded operators. I am only having the problem with those two funcitons. I thought friend functions could directly access the private member variables!
