@xyy_xxyy 你的while循环退出条件不应是x<=n*n，而应该是cik<=n*n，因为n*n求的是输出的汉字点阵图字符总数，要是像你这么写就变成了输入的压缩码字符总数小于等于n，这是不对的。

@youzhanyue 谢谢大佬%%%，已关。

@xyy_xxyy 停，没A

不好意思我还没改完

@xyy_xxyy A了

第一个错误改正后，变成了cik<=n*n，但还不能AC，因为在代码输出完了最后一个字符后，cik加到了n*n，而这一次while循环结束后判断条件时，cik还是等于n*n，所以还会多吃一次输入，这造成输入完了代码还要求要输入一个数。至于改正，只需要将小于等于改成小于就好了。

代码：

#include<bits/stdc++.h>
using namespace std;
int main() {
    int n;
    cin >> n;
    int a;
    int f = 0;
    int cik = 0;
    while (cik < n * n) {
        cin >> a;
        for (int i = 1; i <= a; i++) {
            cout << f;
            cik++;
            if (cik % n == 0) {
                cout << "\n";
            }
        }
        f = !f;
    }
    return 0;
}
```cpp

#include<bits/stdc++.h>
using namespace std;
int main() {
    int n;
    cin >> n;
    int a;
    int sum = 0;
    int f = 0;
    int cik = 1;
    while (cik <= n * n) {
        cin >> a;
        for (int i = 1; i <= a; i++) {
            cout << f;
            cik++;
            if (cik % n  == 1) {
                cout << "\n";
            }
        }
        f = !f;
    }
    return 0;
}

%的时候错了

麻烦上面代码最后的cpp删掉，多打了

by xyy_xxyy @ 2024-01-19 16:44:01

cik不能为0

by TryHardToBeAlive @ 2024-01-19 16:45:22

@xyy_xxyy 嗯两种改法都行，反正最后保证while能够及时退出来就好

by xyy_xxyy @ 2024-01-19 16:46:24

谢谢
