getchar() returns immediately

Question

I'm programming C in Visual Studio 2013 Express for Desktop, and when I use getchar() it terminates immediately.

Here's the code:

#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>

int main()
{
    int num1, num2;
    printf("Enter first number: ");
    scanf("%d", &num1);
    printf("Enter second number: ");
    scanf("%d", &num2);
    printf("Result: %d\n", num1 + num2);
    printf("Press any key to exit...");
    getchar();
}

After the last string is printed, the program exits immediately without waiting for any key press, even though I've used getchar().

Should getchar() wait for a key press (character input), and the move on? Why does it automatically goes on and exits the program, without waiting for key press?

This question comes up on StackOverflow about once a day. I'll see if I can find some duplicates... — Paul R, May 07 '14 at 12:08

The solution is to call getchar(); twice in the end, or to use fgets(); instead.

The problem is, that when you enter a char on the console, you do in fact enter an additional newline each time.
