    Look up command line arguments. Whatever arguments you pass to the program will be saved in two variables passed to main - an int and an array of C style strings. In a simple application you have to parse the strings yourself to see if any of them are valid flags, but it normally isn't very hard.

    a command line function has 2 arguments, an int and a char[]. Int being the number of flags that are supplied, and the char* array being the flags that were set. Setting your main() function to work with this is simple:

    Code:
    int main( int argc, char* argv[] )
    {
        // Do your code
    }
    -"What we wish, we readily believe, and what we ourselves think, we imagine others think also."
    PHP Code:
