C语言基础：switch条件语句使用范例

本范例通过循环和switch语句统计元音字母数量

#include <stdio.h>
void main()
 {
   char letter;
   int vowel_count = 0;
   int consonant_count = 0;   
   
   for (letter = 'A'; letter <= 'Z'; letter++)
     switch (letter) {
       case 'A':
       case 'E':
       case 'I':
       case 'O':
       case 'U': vowel_count++;
                 break;
       default: consonant_count++;
     }; 
 
   printf("The number of vowels is %d\n", vowel_count);
   printf("The number of vowels is %d\n", consonant_count);
 }
