按你的需求，代码如下：
#include<stdio.h>
#include<string.h>
#define max 255
void clear(char arr[]);
int main()
{
char a[max]={0};
printf("请输入一个整数：\n");
gets(a);
clear(a);
printf("%s\n",a);
return 0;
}
void clear(char arr[]) //这个函数很有用，如果有必要，可以记下来
{
int i,j,len;
char temp;
len=strlen(arr);
for(i=0,j=len-1;i<j;i++,j--)
{
temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;
}
}
PS：这段代码不止数字，连字母都是可以逆序的~
希望楼主结合代码来学习，祝楼主学习进步哈~~望采纳~谢谢~
