C++ code to automatically close console

Question

I am currently learning C++ for a programming course. I noticed that my professor's program automatically closes at the end of their program. It usually prompts the user for an input, and then upon entering an input, the program closes. How would I code that? I only know using return 0 gets me "Press Any Key to Continue"

Note: this is a .exe file

Answer 1

If your program doesn't wait for any input, it runs and finally exits from the program. On exiting, the console automatically closes. I assume, to run the program you're clicking on the .exe, as opposed to runnng the program from cmd.exe, or you run the program from visual studio itself without debugging.

Answer 2

You could just put the following line before return 0;:

std::cin.get();

It will wait for some input and then proceed.
