I was wondering..
I use Dev C++ And i know that it uses other exe's within the dev c++ files to do operations and things.

So.. How?
If i make a program like this:

CPP / C++ / C Code:

// hi.exe
#include <windows.h>

int main(int num)
{
     return num*2;
}

and another program:

CPP / C++ / C Code:

// hello.exe
#include <windows.h>

int main()
{
     printl(hi.exe(5),"%d"); // hi.exe(5) is what ever the function is
     system("pause");       // to run hi.exe and put 5 into main.
     return 0;
}

OR another way you would do it?

plz post

You've already called another program from yours and you probably didn't even know it. See the command system("pause"). You are telling your operating system to run a program called "pause". Let's say you wanted to run the program called "hi.exe" with an argument of 10, you would use:

system("hi.exe 10");

Oh and if anyone wants to do somthing like this i made these functions:

CPP / C++ / C Code:

int GetNum(char URL[255],int input) // returns a number when you input a number
{
    char Buffer[255];
    sprintf(Buffer,"%s %d",URL,input);
    int num = system(Buffer);
    return num;
}

CPP / C++ / C Code:

char GetChar(char URL[255],char input) // returns char when you input a char
{
    char Buffer[255];
    sprintf(Buffer,"%s %s",URL,input);
    int num = system(Buffer);
    return num;
}

CPP / C++ / C Code:

char* GetString(char URL[255],char input[255]) // returns string when you input a string
{
    char Buffer[255];
    sprintf(Buffer,"%s %s",URL,input);
    int num = system(Buffer);
    return num;
}

Basically, you need to put in that string whatever you would type in a command-line prompt. So, if you had a path with spaces, I believe that you would need to type the entire path in quotes. Maybe like:

CPP / C++ / C Code:

system("\"C:\\Windows\\My Program Folder\\MyExe.exe\" 10");
