      printf("var1 = |%c| can be printed\n", var1 );
   } else {
      printf("var1 = |%c| can't be printed\n", var1 );
   }

   if( isgraph(var2) ) {
      printf("var2 = |%c| can be printed\n", var2 );
   } else {
      printf("var2 = |%c| can't be printed\n", var2 );
   }

   if( isgraph(var3) ) {
      printf("var3 = |%c| can be printed\n", var3 );
   } else {
