#include <stdio.h>

     return 0;

@mmmath3

@pmkmzfuzsotqotmzs 他让你帮忙改，不是要代码。

@mmmath3 改好了：

#include <stdio.h>
int main()
{
    int n;
    scanf("%d",&n);
    int a,b,c,d = 0,i;
    b=0;
    i,c=1;
    for (i;b<=n*n;i++){
        a=0;
        scanf("%d",&a);
        b = b+a;
        c = 1-c;
        int j=1;
        for (j;j<=a;j++){
            d++;
            printf("%d",c);
            if (d%n == 0)   printf("\n");
        }
      if (b * b >= n) break;
    }
     return 0; 
}

@mmmath3 你的问题：

1. d 没有初始化

2. 没有特判输入结束，使得程序一直无法退出

给个关注呗

@EricWan 好的好的，谢谢大佬
