为什么不管n为任何值输出的y都是1

#include<iostream>
#include<cmath>
using namespace std;
int main(){
    int n,sum=0,sum1=0,y,u;
    cin>>n;
    int a[100];
    for(int y=1;sum<(n*n);)
    {
    cin>>a[y];
    sum+=a[y];
    y++;}cou<<y;
        return 0;
}

cou<<y??????

你都定义了y还int y=1干嘛

改成for(y=1;sum<(n*n))

@qew12312 请问楼主是不会复制粘贴吗？cou<<y都出来了

@qew12312 楼主是交错题了吗，总感觉这两个东西搭不上边啊

        }
    }
        return 0;
}   
    //这是原码，刚才只是拿来调试的

@lazy_doghead 改了还是不对诶

by Joker_lazydoghead @ 2023-01-09 10:58:32

for(y=1;sum<n*n;y++)
    {
    cout<<a[y];
    sum+=a[y];}

???

不应该是cin吗

改了cin还是不对，诶
