在switch语句中可以嵌套另一个子switch语句。
嵌套switch - 语法
switch(ch1) {
case 'A':
printf("This A is part of outer switch" );
switch(ch2) {
case 'A':
printf("This A is part of inner switch" );
break;
case 'B': /* case code */
}
break;
case 'B': /* case code */
}
`
嵌套switch - 示例
#include <stdio.h>
int main () {
/* local variable definition */
int a=100;
int b=200;
switch(a) {
case 100:
printf("This is part of outer switch\n", a );
switch(b) {
case 200:
printf("This is part of inner switch\n", a );
}
}
printf("Exact value of a is : %d\n", a );
printf("Exact value of b is : %d\n", b );
return 0;
}
编译并执行上述代码时,将生成以下结果:
This is part of outer switch
This is part of inner switch
Exact value of a is : 100
Exact value of b is : 200
