#include<stdio.h>
int main()
{
    int i,n,N
    int flag=0;//控制0,1转换
    int count=0;//计数控制换行
    int sum=0;
    scanf("%d",&N);
    while(sum!=N*N)
    {
        //printf("a");

        scanf("%d",&n);
        sum+=n;
        if(flag==0) 
            for(i=1;i<=n;i++)
        {
            printf("0");
            flag=1;
            count++;
            if(count%N==0) printf("\n");
        }
        else if(flag==1) 
            for(i=1;i<=n;i++)
        {
            //sleep(1);
            printf("1");

    }
    return 0;
}

可能会有0，如果有0的话，你这样写，就不翻了

@Red_Cow 你可以把翻转写在循环下面

这应该是可以过的呀

by GTAH2333 @ 2023-11-05 18:34:08

好吧，收回我的话

如 liuyidu 所说

if(flag==0){
    flag=1;
    for(i=1; i<=n; i++) {
        printf("0");
        count++;
        if(count%N==0) printf("\n");
    }
}else if(flag==1){
    flag=0;
    for(i=1; i<=n; i++) {
        printf("1");
        count++;
        if(count%N==0) printf("\n");
    }
}

@liuyidu 恍然大悟，感谢解答
