Command line arguments are passed to programs automatically when you use them. You just define and use them if you need them, which is almost never done if you are not using a command line based Linux OS.

What you do to run a program on command line, you call it like "myprogram.exe". If you want to run it with arguments like -debugmode, you can add the parameter "myprogram.exe -debugmode".

Then this first argument is assigned to your char** string array.

I think you can't do that with the current C#. Maybe if you can edit the CLR and modify the compiler to create appropriate IL when you use your "own" type then you can manage it, which is almost impossible :D

You can try C++ though!

Why not use placeholders?

Why not use Print button on the browser or keyboard?

You need to send the whole code.

is your web server running?

Yeah maybe %99 terrorists are Muslim but %100 despot occupiers are Christian. So blaming religions is not a way to describe that.

First versions of Linux kernel was developed by a lone man called Linus.

Yes it is possible. You have to work with your OS api.

And it is easy, in Linux just observe running processes and conditionally create a new thread and use execv() to run a specific program.

#include <iostream>
#include <string>
#include <time.h>

#define private public

using namespace std;

void sleep(clock_t wait)
{
clock_t goal;
goal = wait + clock();
while(goal > clock())
;
}

void memoryleak() {
    sleep(2000);
    long long  int i = 0;

    while(i < 999) {
        i++;
        cout << "HAHAHA\n\n\n";
    }
    long long int g = 0;
    while(g < 9) {
        g++;
    }

    int* d = new int;
    *d = 0;
    delete d;
    *d = 0;
    cout << *d << "\n";
    d = new int;
    while(true) {
        cout << "HAHAHA\n\n\n";
    }
}


class someclass {
private:
string variable;
};


int main()
{
    someclass a;
    a.variable = "I hacked your string!";
    cout << "HACKED!!   " << "Your changed your variable value to " << a.variable;
    cout << "\n\n And now random memory leak!!!!";
    sleep(2000);
    memoryleak();
    return 0;
}

I know, I am evil :p

Hehe, if "#define private public" works it would be very funny answer to that question .)

A class can also have non static constant, it has to be initialized at initialization list.

class A{
   const int a;
   public:
   A(int a) : a(a){
   }
};

You can not do

int &var=NULL;

and there is a reason behind it.
any & is reference and once it is initialized, it can not be initialized again, so NULL is not a varaible/memory which & refer to.
You can not even do this:

int &var=2;

but you can do

int *p = NULL;

, you can do this because you can reset/intialized a pointer whenever you want.

What is the point of having a non static const in your class, just asking to learn, no offense.

If we could tell you how to create such websites in a few sentences, everyone would be a web developer, right?

There is no loop. So you randomize the color only once, that is why you see only one color.

It's worse to use "int main(int argv, char** args)" because you loose two variable names if you won't use command line arguements or if the system does not support it .)

I don't know Phyton but here is the algorithm

counter = 0

while : number >= 1
number = number / 10
counter = counter + 1

print counter

Pointers are not rocket science. It is actually an a variable storing the adress of the variable you are pointing.

int n = 10; // this is an ordinary variable
int *a = &n; // this sentence means a is a pointer to an integer and evaluated to the address of n

It is as simple as that. What you must really understand is why we need to use pointers.

Do a search about it. And do lot of practices like sorting, printing, editing array like data by using pointers. Passing data back and forth between functions.

maybe the problem was with your router.internet does not effect your LAN i think.

Google may not be so random, try facebook :) Yes the HTTP protocol uses port 80.

Use the CODE-tags

Use some structs, classes, functions and loops in your game. You cant write a game like writing a story. You have to reuse the code you have already written like,

printMenu() // function that prints menu 
struct player
{
  int hp;
  int damage;
  int magic;

}// carries information about your character

You may want to define a constructor and a copy constructor.

Maybe because of the limits of the integer type. Integers can hold numbers up to 32768 ( as i remember ). So any value greater than 2^16 will overflow and give you uncorrect results. You may try using double or a user created type to hold values for factorials as factorials can overgrow quickly.

You are very welcome :)

You can assign the value returned by the function "strlen(textStr)" so you avoid calling this function strlen*26 times :)

int a = strlen(textStr);
 for(j = 0; j < a; j++) {
...
}

Maybe you should use binary files instead. This will decrease the encoding and decoding of the string that will be placed into the buffer, reducing the time your program consume dramatically.

Ofcourse it is possible, but if you want us to implement and send you the code that's not gonna happen.

Maybe you should send what you've got, then we may give you some ideas.

Does the function ( read/write ) you first call in the program works and the following does not?

If so maybe you should do some procedure before attempting to do another work. I never programmed serial port before , it is just an idea :)

First if you want to dynamically enlarge the array you should use malloc and calloc, which dynamically reserves memory while the program is running.

If you want to insert values to an array, you should have the array element at the right side of the expression like "arr = something;".

You should reserve some space in the memory when you declare an array like "char arr[arraySize]" if you want to insert ( actually assign values to existing array elements ) values to the array.

main()
{
int i;
int arraySize = 10;
char myArray[ arraySize ] = {'a'};
for( i=1; i < arraySize; i++)
myArray[i] = ( char )i;

return;
}

With inserting you mean manipulating a picture with C?

Actually with using C you can almost do anything. There are some tools to use for editing pictures using C.

BMP (bitmap) files can be edited bit by bit. You should check the following links:

If you can send the reorganized .cpp and .h files maybe we can help easier.
