如果有两个同学生日相同，输入靠后的同学先输出

然后建议你学一下swap函数

swap我会

by WangSiHan_2011 @ 2024-11-08 12:37:39

然后建议你加一下 return 0;

by LMR_Minecraft @ 2024-11-08 12:38:10

@WangSiHan_2011 谢谢了,我会用swap,已发现错误,谢了

@WangSiHan_2011 新程序(最后一个样例没过)

#include<iostream>
using namespace std;
int n;
int a[100], b[100], c[100], x[100];
string s[100], temp;

int main() {
    cin >> n;
    for (int i = 0; i < n; i++) cin >> s[i] >> a[i] >> b[i] >> c[i];

    for (int i = 0; i < n; i++) {
        for (int j = i + 1; j < n; j++) {
            if (a[i] > a[j]) {
                swap(s[i], s[j]);
                swap(a[i], a[j]);
                swap(b[i], b[j]);
                swap(c[i], c[j]);
            }
            else if (a[i] == a[j]) {
                if (b[i] > b[j]) {
                    swap(s[i], s[j]);
                    swap(a[i], a[j]);
                    swap(b[i], b[j]);
                    swap(c[i], c[j]);
                }
                else if (b[i] == b[j]) {
                    if (c[i] > c[j]) {
                        swap(s[i], s[j]);
                        swap(a[i], a[j]);
                        swap(b[i], b[j]);
                        swap(c[i], c[j]);
                    }
                }
            }
        }
    }

    for (int i = 0; i < n; i++) cout << s[i] << endl;
}
