Thread: help Passing Arguments

If you have a program called "Hello.Exe" for example and you type the following:

Hello C:\Temp C:\Windows 500 -X

Then what gets passed into the main function via the argc and argv variables are:

argc = 5
argv[0] = "Hello" <- Actually this may be something like C:\Progs\Hello.exe
argv[1] = "C:\Temp"
argv[2] = "C:\Windows"
argv[3] = "500" <- If you want this to be an int, you will need to convert it.
argv[4] = "-X"

If you want to create a simple test program to try this out, compiler and run this:

Code:

int main( int argc, char* argv[] )
{
    int iLoop;
    for( iLoop = 0; iLoop < argc; iLoop++ )
        prntf( "Argument %d is %s.\n", iLoop+1, argv[iLoop] );
    return 0;
}

Run it at the command prompt and pass in some arguments, numbers, character strings, etc. See what happens!
