回复3楼：我运行了楼中的程序出现以下结果：

Error executing cl.exe.

1111.exe - 40 error(s), 1 warning(s)

这是为什么呢，如何解决？

#include<stdio.h>
#include<math.h>

int main()
{
    int a = 3, b, c, d, e, f, g, h, l, m;//a是数 ，b是被判断位数的数， c是位数。

    for (; a <= 1000000000; a++)
    {
        b = a;
        c = 1;
        h = 0; //h一个循环里面都要清零
        while (b >= 10)
        {

            b /= 10;
            c++;
        }
        f = c;
        b = a;
        do
        {
            e = 1;
            d = 1;
            for (; d < f; d++)
            /*for (d = 1; d < f; d++) 如果再循环的话 d是等于1 还是是f-1*/
            {
                e = e * 10;
            }
            f -= 1;
            g = b / e;

            /*h += pow(int g,int c);*/ //这个怎么用
            l = 1;
            m = 1;
            for (; l <= c; l++)
            {
                m *= g;
            }
            h += m;
            b -= g * e;
        } while (f >= 0);
        if (h == a)
        {
            printf("%d\t", a);
        }
    }
    return 0;
}

自己写的 希望能帮到
