Answer 1

There are two choices, depending on what kind of program you are building.

• If your program is a console mode program, use argc and argv parameters passed to your main() .
• If your program is a GUI mode program, use the pCmdLine parameter passed to your WinMain() .

In either case, you can always use GetCommandLine() .

Answer 2

Assuming you write your entry point something like this:

int main(int argc, char* argv[])

Then argc is the number of arguments used to invoke your program and argv are the actual arguments.

Try it out:

#include <cstdio>

int main(int argc, char* argv[])
{
    for (int i = 0; i < argc; ++i)
        printf("%s\n", argv[i]);
}

Answer 3

#include <stdlib.h>
...
system("IExplore.exe google.com");
