用char数组3 WA 求解

P5705 【深基2.例7】数字反转

ymls667 @ 2020-12-29 00:14:05

#include<stdio.h>
#include<string.h>
int main()
{
    char a[7];
    scanf("%s",&a);
    for (int i = strlen(a);i >= 0;i--)
    {
        printf("%c",a[i]);
    }
    return 0;
}

为什么这一串代码在本地输入输出都没问题，都是提交上去就WA了呢，大神们求解！

&a？不是a吗，数组名=数组地址

还有int i=strlen(a)要改成int i=strlen(a)-1，为了不越界

#include<stdio.h>
#include<string.h>
int main()
{
    char a[7];
    scanf("%s", a);
    for (int i = strlen(a) - 1;i >= 0;i--)
    {
        printf("%c",a[i]);
    }
    return 0;
}
