I just ran your program and got results..What are you compiling/running this on?

Its simple really. First, create the memory for your c-strings and then read into them. One method [code] #define ARR_SIZE 100 char cstring1[ARR_SIZE];/*100 character array*/ char cstring2[ARR_SIZE];/*100 character array*/ fgets(cstring1, ARR_SIZE, stdin);/*read into cstring1 from the stdin*/ fgets(cstring2, ARR_SIZE, stdin);/*read into cstring2 from the stdin*/ [/code]

Here's a good example hitting the high points of your question. [url]http://www.metalshell.com/source_code/89/Variable_Argument_List_Example.html[/url] [url]http://msdn.microsoft.com/en-us/library/kb57fad8.aspx[/url]

First question, you start thread with [code] newThread.Start(DataTimes) [/code] Where is DataTimes defined?

Try something like below and it worked for my system. [code] #include <stdio.h> void showbits (unsigned char n) { unsigned char i = 8; for (; i > 0; i--) { n & (1 << (i - 1))? printf ("1"):printf ("0"); } } int main() { unsigned char j = …

It doesn't work because the member function 'test' has no idea what pAVec is. pAVec is an instance of the object Member created in main. If you require a copy or reference of pAVec in test then pass it via a function parameter.

Uninitialized arrays are bitwise zeroed..The values for a uninitialized int array are zero.

Why won't you make the parameters unsigned integers?

Wow, where to begin? First I would get rid of the idea of two arrays and combine them into one array of structures..Like so. [code] struct mys { char * name; int studid; }; struct mys thes[10]; [/code] Before we get into the nuts and bolts..In a C program the …

You would probably have better luck with something else...Try getting the MAC address of the network card, that's supposed to be unique.

Maybe if you look at this code you'll see what the this pointer is... [code] #include <iostream> class myint { public: myint(int val):itsvalue(val) {} int getitsvalue() const { return itsvalue; } void* get_this() const { return (void*)this; } private: int itsvalue; }; int main(int argc, char**argv) { myint me(1234); std::cout …

Narue beat me to the punch... [code] #include <iostream> struct ch8_struct { int field1; short field2; char field3; int field4; double field5; }; int main(int argc, char**argv) { struct ch8_struct g_StructArray[3]; struct ch8_struct *g_pStructArray = g_StructArray; struct ch8_struct **g_ppStructArray = &g_pStructArray; for (int i = 0; i < 3; ++i) …

Maybe you should've of asked some questions in your class. On a different note. The forum frowns on students posting homework questions and asking for solutions. Please post what you've accomplished so far and ask specific questions about specific problems.

I would look into the modulus operator using it something like below. [code] using System; namespace testit { class MainClass { public static void Main (string[] args) { UInt64 x = 0; Console.Write("Enter a four digit number->"); x = UInt64.Parse(Console.ReadLine()); Console.WriteLine(reverse_it(x)); } public static UInt64 reverse_it(UInt64 num) { UInt64 reverse …

On line 57...Try initializing your double variables to 0.0

Yes its possible, that's why it has the void* args parameter.

Your giveMemoryBack function should be [code] int giveMemoryBack (int *pCDROM, int *pCDROM2, int *pCDROM3) { delete pCDROM1 delete pCDROM2 delete pCDROM3 return 0; } [/code] Note: Remember to set the original pointers back to NULL. Found something else, your function call [code] // Call giveMemoryBack function int giveMemoryBack(int *pCDROM1, int …

Connecting to a MySql database manually is not the way to go...Download the MySql developer files and use that library(MySql's). Note the enclosed code [code] #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #include <string.h> #include <mysql.h>//Note the mysql header file #define SEL_QUERY "select * from personal where lastname = '" #define …

If you examine the strchr prototype you'll note it doesn't take a c-string for the second parameter. [code] char *strchr(const char *s, int c); [/code] You'll have to do more than one search if you use this function.

Shouldn't you do your totalPayroll += payrollAmount in the inner loop? As it is, your inner loop just prompts for and accepts a value for payrollAmount.

So going from a meager understanding of scanf to posix threads.

I just copied and ran your program and it worked.

You could create a dynamic array with the operator new. [code] int * a = new int[size]; [/code]

If your scanf'ing a variable, you must use the address of the variable...If the variable name is an address(like character arrays) then you don't have to use the address of operator on it. example [code] char my_str[] = "This is my string"; int x = 1234; scanf("%s", my_str);//my_str is an …

A question off-topic [code] #include<iostream.h> [/code] What examples/materials are you using that recommend iostream.h?

Try this [code] scanf("%s",stud1.oname);//remove the & [/code]

Line 97. What is this [code] if(s[i].sMaxCap <= h[0,1,2,3,4,5,6,7,8,9].maxCap) [/code]

Try running your code with a debugger.

left node and right node where left node is greater that right node.

Please show us what you have so far.

try [code] float.TryParse(txtInitialTemp.Text, out temp) [/code]

For Linux Kernel Modules I just use [code] obj-m += test.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean [/code]

A big hint is the function name - findnoise. I think the function is grabbing whatever stack value int x happens to have and then applying some operations on it...Hopefully returning a quasi random number. Please note this is just a guess....Actually I never noticed the function passed an int …

You could try something like below [code] #include <stdio.h> #include <stdlib.h> #include <ctype.h> unsigned long int readNumbersByGetchar() { unsigned long int thisNumber = 0, i = 0; while ((i = getchar()) != '\n') { if (isdigit(i)) { thisNumber *= 10; thisNumber += atoi((char*)&i);/*This only works for Intel/AMD type integers*/ } …

First question. What are you trying to do here? Are you trying to create a Windows form with a progress bar? If you are, this simple example should work. [code] using System; using System.Drawing; using System.Windows.Forms; class myform: Form { ProgressBar my_bar; public myform() { my_bar = new ProgressBar(); my_bar.Minimum …

In your for statement [code] for(i = 0; i < 10; i++) { printf("value, deference pointer, address \n"); printf("pointer1 = %p, *pointer1 = %d, &pointer1 = %p\n", pointer1, *pointer1, &pointer1); pointer1++;//this line should go last } [/code] Or better yet. [code] #include <stdio.h> int main(void) { int values[10] = {1,2,3,4,5,6,7,8,9,10}; …

[QUOTE=aKiLa.. :);1665425]what all should i include to make it look decent?[/QUOTE] A lot of work....

You would be better served if you created an array of structures. [code] #include <stdio.h> #include <stdlib.h> struct mys { int id, size, PerBox; double Price; }; int main() { struct mys thes[5]; return 0; } [/code]

Because the data member is const the = operator can't change its value. So using the = operator on any objects from this class will cause an error. Your = operator is defined ~ like so [code] A& A::operator =(const A & obj) { if (this != &obj) { a …

Then you have to explicitly refer to the members [code] public void a.b() { // TODO: Add Class1.d implementation } [/code]

[QUOTE=shawn.reynz;1665898]please help me.. contribute some codes for indegree and outdegree .. i need it badly[/QUOTE] How about you contributing what you have so far.

Try googling C++ string erase.

[QUOTE=tkud;1665544]Declare the variables globally.i.e before main() [/QUOTE] Yikes...Is that good advice? Try reading up on references or pointers. I would try references first before plunging into pointers. Simple reference example. [code] #include <iostream> void square_it(int & i)//pass by reference { i *= i; } int main() { int i = …

Try running this code [code] #include <stdio.h> int main(void) { float i=3.3; fprintf(stdout, "%f\n", i - 3.3); fprintf(stdout, "%f\n", 3.3 - i); return 0; } [/code]

[QUOTE=Alvi89;1665521]people i still cant figure out the problem :O[/QUOTE] We can't figure out what the problem is...Posting a chunk of code and stating that it doesn't work and then giving a brief but confusing explanation doesn't help us.

Try initializing TP to 0.0.

Try initializing your array elements before you pass them to your function....Just like your error message indicated.

[QUOTE=Labdabeta;1664881]So it seems like I should use a DLL, but how do I use a DLL?[/QUOTE] That's operating system specific...Which operating system are we talking about here?

It should be [code] fraction fraction::addFractions(fraction two) { //... } [/code]

I would try a static member function in myclass to construct the 'hidden' class.
