Question

I’m currently trying to make a small application that performs different duties. Right now I have a console app pop up and ask what I want to do, but sometimes I would rather just launch it with something like MyApp.exe -printdocuments or some such thing.

Are there any tutorials out there that can show me a simple example of this?

Answer 1

In C++, your main() function can have argc and argv parameters, which contain the arguments passed on the command line. The argc is the count of arguments (including the executable name itself), and argv is an array of pointers to null-terminated strings of length argc.

For example, this program prints its arguments:

#include <stdio.h>  int main(int argc, char *argv[]) {     for (int i = 0; i < argc; i++) {         printf('argv[%d]: %s\n', i, argv[i]);     }     return 0; } 

Any C or C++ tutorial will probably have more information on this.
