@zajiu 把循环里的if和else删掉看行不行

by zhangyicheng1010 @ 2024-05-18 13:41:22

只留``` c += q;

有点多余...

#include <stdio.h>
using namespace std;

int main() {
    int n, i;
    double sum = 0;
    scanf("%d", &n);
    for (i = 1; i <= n; i ++) {
        int a;
        scanf("%d", &a);
        sum += a;
    }
    printf("%.2lf", sum/n);
    return 0; 
}

@0x3E 你看看人家什么头文件？

by jinrunsen @ 2024-08-21 15:25:27

万能头文件解决一切

• include<bits/stdc++.h>

@jinrunsen 不能解决<windows.h>

@lcy20100722 是我格局小了
