Edit Question
Title
Body
I want to know how and when can I use the exit() function like the program in my book: #include<stdio.h> void main() { int goals; printf("enter number of goals scored"); scanf("%d",&goals); if(goals<=5) goto sos; else { printf("hehe"); exit( ); } sos: printf("to err is human"); } When I run it, it shows ERROR: call to undefined function exit() . Also, I want to know how I can create an option to close the window in which the program runs? For example, I made a menu-driven program which had several options and one of them was "exit the menu" . How can I make this exit the program (i.e. close the window)?
