《输入字符串，倒序输出》无法正确输出结果

Question

#include <stdio.h>
int main()
{
printf("请输入要倒序的内容\n");
char s = scanf("%c");
char a[65536] = {'\0'};
a[65536] = s;
char *t = &a[0];
int len = 0;
while (*t != '\0')
{
printf("第%d个字符：%c\n",len,*t);
len++;
t++;
}
printf("共计%d个字符\n", len);
for (int i=len;i>0;i--)
{
printf("%c",*t);
t--;
}
return 0;
}

Answer 1

#include <stdio.h>
#include <string.h>
int main()
{
    printf("请输入要倒序的内容\n");
    char s[250];
    gets(s);
    char a[65536] = {'\0'};
    int len = strlen(s),j;
    for (j=0; j<len; j++)
    {
        printf("第%d个字符：%c\n",j+1,s[j]);
    }
    printf("共计%d个字符\n", len);
    for (int i=len-1; i>=0; i--)
    {
        printf("%c",s[i]);
    }
    return 0;
