数组也要是浮点数

还有输出有问题

一定要用printf吗

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,a[105],x=0;
    for(int i=0;i<n;i++){
        cin>>a[i];
    }
    for(int i=0;i<n;i++){
        if(a[i]>=x){
            x=a[i];
        }
    }
    cout<<x;
    return 0;
}

这个也帮忙看一下

没过

@Yjkaixuexi 吐槽一句:你没发现n没输入吗？ 更优解:

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n,x,maxn,i;
    cin>>n>>x;
    maxn=x;
    for(i=2;i<=n;i++){
        cin>>x;
        if(maxn<x) maxn=x;
    }
    cout<<maxn;
    return 0;
}

@Yjkaixuexi 最好用printf,方便又正确
