Use of exit() function

Question

I want to know how and when can I use the exit() function like the program in my book:

#include

void main()
{
    int goals;
            


        

Answer 1

Include stdlib.h in your header, and then call abort(); in any place you want to exit your program. Like this:

switch(varName)
{
    case 1: 
     blah blah;
    case 2:
     blah blah;
    case 3:
     abort();
}

When the user enters the switch accepts this and give it to the case 3 where you call the abort function. It will exit your screen immediately after hitting enter key.
