How can I terminate an infinite loop in Turbo C

Question

I get caught in an infinite loop. 

How can I break this cycle? 

Cntrl-C was attempted, however it had little effect. 

I have no idea how to stop it.

main()
{
     while (1)
     {
          char ch;
          printf("Enter a character: \n");
          ch = getche();
          printf("\nThe code for %c is %d.\n", ch, ch);
     }
}
