C exit from infinite loop on keypress

Question

How can I exit from an infinite loop, when a key is pressed? Currently I\'m using getch, but it will start blocking my loop as soon, as there is no more input to read.

Answer 1

// Include stdlib.h to execute exit function
int char ch;
int i;

clrscr();
void main(){

printf("Print 1 to 5 again and again");
while(1){
for(i=1;i<=5;i++)

     printf("\n%d",i);

    ch=getch();
    if(ch=='Q')// Q for Quit
     exit(0);

    }//while loop ends here

    getch();
    }
