Switch Statement Examples

1. Example 1
   int choice;
   scanf("%d", &choice);

   switch (choice){

   case 0:
   printf("Bye Bye, see you later \n");
   break;
   case 1:
   printf("Yana\n");
   break;
   case 2:
   printf("Guy\n");

   case 3:
   printf ("Michal\n");
   break;
   case 4:
   printf("Yael\n");
   break;
   default:
   printf ("Illegal Choice!\n");
   break;
   }

   Example 2

   int choice;

   scanf("%d", &choice);

   switch (choice){

   case 0:
   printf("Bye Bye, see you later \n");
   break;
   case 1:
   printf("Yana\n");
   case 2:
   printf("Guy\n");
   case 3:

   break;
   case 4:
   printf("Yael\n");
   default:
   printf ("Illegal Choice!\n");
   break;

   }

   Example 3

   char letter;

   int uppercase, lowercase;

   int value;

   letter = getchar( ); /* function getchar() reads one character from the keyboard */

   switch (letter){

   case 'a':
   case 'A':
   uppercase = 'A';
   lowercase = 'a';
   printf("%d, %d", uppercase, lowercase);
   break;
   case 'b':
   case 'B':
   value = letter;
   printf("the ASCII value of the character %c is %d", letter, value);
   break;
   case 'c':
   case 'C':
   printf("%d", letter);
   break;
   default:
   printf ("Illegal letter!\n");
   break;

   }

   Example 4

   char letter;

   int aCount = bCount = cCount = restCount = 0;

   while( (letter = getchar( ) ) ! = EOF ){

   switch (letter){

   case 'a':
   case 'A':
   uppercase = 'A';
   lowercase = 'a';
   aCount++;
   break;
   case 'b':
   case 'B':
   bCount++;
   break;
   case 'c':
   case 'C':
   cCount++;
   break;
   default:

   restCount++;
   break;

   }

   }

   printf("%d, %d, %d, %d\n ", aCount, bCount, cCount, restCount);
