Microsoft C Version 6.00 and QuickC Version 2.50, in accordance with the ANSI-draft standard, now support both long and unsigned long values in switch expressions and case constants.

Previously, only char and int types were allowed in switch statements.

Code Sample

  1. include <stdio.h>

unsigned long SwtchVal = 4L ;

void main(void) { switch( SwtchVal ) case 4L : printf(" SwtchVal = %ld ", SwtchVal ) ; }
