有三个数组char *a[] ={"1","2"}；char *b[] ={"aa","bb"};char *c[] ={"cc","dd"};

Question

有三个数组char *a[] ={"1","2"}；char *b[] ={"aa","bb"};char *c[] ={"cc","dd"};C语言实现，当a[0]的时候打印数组b里的内容，当a[1]的时候打印数组c里的内容

Answer 1

#include<string.h>
main()
{
char *a[]={"1","2"},*b[]={"aa","bb"},*c[]={"cc","dd"},s[2];
scanf("%s",s);
if(!strcmp(s,*a))
    printf("%s,%s",*b,*(b+1));
if(!strcmp(s,*(a+1)))
printf("%s,%s",*c,*(c+1));
}

追问

能否用for循环实现

#include<string.h>
main()
{
    char *a[]={"1","2"},*b[]={"aa","bb"},*c[]={"cc","dd"},s[2],i,j;
    scanf("%s",s);
    if(!strcmp(s,*a))
        for(i=0;i<2;i++)
        {
            for(j=0;j<2;j++)
                printf("%c",*(b[i]+j));
            printf(" ");
        }
    if(!strcmp(s,*(a+1)))
        for(i=0;i<2;i++)
        {
            for(j=0;j<2;j++)
                printf("%c",*(c[i]+j));
            printf(" ");
        }
}

#include<string.h>
main()
{
    char *a[]={"1","2"},*b[]={"aa","bb"},*c[]={"cc","dd"},s[2],i,j;
    scanf("%s",s);
    if(!strcmp(s,*a))
        for(i=0;i<2;i++)
        {
            for(j=0;j<2;j++)
                printf("%c",*(b[i]+j));
            printf(" ");
        }
    if(!strcmp(s,*(a+1)))
        for(i=0;i<2;i++)
        {
            for(j=0;j<2;j++)
                printf("%c",*(c[i]+j));
            printf(" ");
        }
}

Answer 2

a[0]只打印"aa"？ 还是打印"aabb"?
