switch和数组两种方法对不同输入做不同响应

#include<stdio.h>

int main(void)

{

int i;

scanf("%d",&i);

switch(i)

{

case 1:

printf("who\n");

break;

case 2:

printf("what\n");

break;

case 3:

printf("when\n");

break;

case 4:

printf("where\n");

break;

case 5:

printf("why\n");

break;

default:

printf("don't know\n");

break;

}

return 0;

}

#include<stdio.h>

int main(void)

{

int i;

char *str[5]={"who","what","when","where","why"};

scanf("%d",&i);

if(i<=5&&i>=1)

printf("%s\n",str[i-1]);

else

printf("don't know");

return 0;

}
