@cancan1030 max需要赋初始值

by cancan1030 @ 2023-06-11 14:58:24

@Haoomff 这样吗？还是不行啊

#include<bits/stdc++.h>
using namespace std;
struct student
{
    string name;
    int chi;
    int mat;
    int eng;
    int all;
};
int main()
{
    int n;
    cin>>n;
    student a[n],max;
    max.chi=0;
    max.mat=0;
    max.eng=0;
    max.all=0;
    for(int i=0;i<n;i++)
    {
        cin>>a[i].name>>a[i].chi>>a[i].mat>>a[i].eng;
        a[i].all=a[i].chi+a[i].mat+a[i].eng;
        if(a[i].all>max.all) max=a[i];
    }
    cout<<max.name<<" "<<max.chi<<" "<<max.mat<<" "<<max.eng;
    return 0;
}

@cancan1030 赋值-99

by _Haoomff_ @ 2023-06-11 15:01:09

@cancan1030 其实max和all都不用这样用的

by cancan1030 @ 2023-06-11 15:01:12

@Haoomff 成了，感谢

by cancan1030 @ 2023-06-11 15:01:48

@Haoomff 哦？

by _Haoomff_ @ 2023-06-11 15:03:55

max初值赋为-99，all替换为一个计算总分的变量。每次计算出总分后，跟max比较一下，若大于max，max=现在的总分，并把现在的位置记录下来

for(int i=0;i<n;i++){
        cin>>a[i].name>>a[i].c>>a[i].m>>a[i].e;
        cnt=cnt+a[i].c+a[i].m+a[i].e;
        if(cnt>Max){
            Max=cnt;
            j=i;
        }
    }

（这份代码前年打的，丑且变量乱用，懂就行，勿喷）

不好意思，少了一个cnt=0没复制进……
