我用穷举，这个为什么有毛病#include<stdio.h>
int main(){
    int a,b,c,d,e,f,g,h;
    for(a = 1;a <= 765;a++)
        for(b = 1;b <= 765;b++)
            for(c = 1;c <= 765;c++)
                for(d = 1;d <= 765;d++)
                    for(f = 1;f <= 765;f++)
                        for(e = 1;e <= 765;e++)
                            for(g = 1;g <= 765;g++)
                                for(h = 1;h <= 765;h++)
                                    if(b / a == 2 && c / b == 2 && d / c == 2 && e / d == 2 && f /e == 2 && g / f == 2 && h / g == 2)
                                    {
                                        printf("the first floor has %d\n",a);
                                        printf("the eight floor has %d\n",h);
                                    }
}

这个又有什么毛病啊
#include<stdio.h>
int main(){
    int i,sum = 0,n,m = 1;
    while(1)
    {
        n = m;
        sum = m;
        for(i = 1;i <= 8;i++)
        {
            m *= 2;
            sum += m;
        }
        if(sum == 765)
        {
            printf("%d\n",n);
            printf("%d",m);
        }  
        m = n;
        m++;
    }
}

这个我知道哪里错了

哦哦，原来如此，感谢
