學點 C 語言(10): switch 語句

1. 常規:

#include <stdio.h>int main(void){    int i;    for (i = 0; i 

2. 省略 default:

#include <stdio.h>int main(void){    int i;    for (i = 0; i 

3. 相同結果:

#include <stdio.h>int main(void){    int i;    for (i = 0; i 

4. 用於字元:

#include <stdio.h>int main(void){    char c;    for (c = 'A'; c 

5. 用於枚舉:

#include <stdio.h>int main(void){    enum ABCD {AAA,BBB,CCC,DDD} e;    e = CCC;    switch (e) {        case AAA: printf("%d.AAA\n", e); break;        case BBB: printf("%d.BBB\n", e); break;        case CCC: printf("%d.CCC\n", e); break;        case DDD: printf("%d.DDD\n", e); break;    default:        ;    }                getchar();    return 0;}
