程序代码：

#include<stdio.h>
int main()
{
    void fun(char *); //void fun(); 函数声明形参没有
    char s[19];
    fun(s);
    return 0;
}
void fun(char* w)
{
    int i, x, y;
    for (i = 1, y = 0; i <= 100; i++)
    {
        x = i; y = 0; //y 复位归零
        while (x > 0)
        {
            *(w + y) = x % 10;
            x /= 10;
            y++;
        }
        *(w + y) = '\0';
        for (x = 0, y = y - 1; x < y; x++, y--)
            if (*(w + x) == *(w + y))
                continue;
            else
                break;
        if (x >= y)
            printf("******%d\n", i);
    }
}
