The cause is file buffering. As printf(...) is somewhat like
fprintf(stdout,...), output is buffered and you need fflush(stdout) 
after printf to force text to appear. Buffer is automaticaly flushed 
after printing '\n' and before program exits. So use either
 printf("Before getch\n"); or printf("Before getch"); fflush(stdout);
