#include<stdio.h>
int main()
{    int n=1,m=2,i=1,sum=2;
    for(i<20;i++)
        n=m;
        m=n+m;
        sum=sum+m/n;
        printf("%d\n",sum);
        return 0;
}

我试试

C:\Program Files\Microsoft Visual Studio\MyProjects\ZXA\是.cpp(4) : warning C4552: '<' : operator has no effect; expected operator with side-effect
C:\Program Files\Microsoft Visual Studio\MyProjects\ZXA\是.cpp(4) : error C2143: syntax error : missing ';' before ')'不知道什么错误，加了大括号了

c:\program files\microsoft visual studio\myprojects\zxaa\第10题.cpp(10) : fatal error C1010: unexpected end of file while looking for precompiled header directive
