简单的一批

不用for循环的代码：

}

}

return 0;
}

求指点代码还可以简化吗？

这是一道很简单的模拟题，一个循环即可。

#include<cstdio>
#include<iostream>
using namespace std;
int a[11],ans,x;
int main(){
    for(int i=1;i<=10;i++){
        cin>>a[i];
    }
    cin>>x;
    x=x+30;
    for(int i=1;i<=10;i++){
        if(a[i]<=x) ans++;
    }
    cout<<ans;
    return 0;
}

#include<bits/stdc++.h>
using namespace std;
int main()
{
int a[10];
int n,h,ans=0;
for(int i=1;i<=10;i++)
cin>>a[i];
cin>>n;
h=n+30;
for(int i=1;i<=10;i++)
if(h>=a[i])
ans++;
cout<<ans<<endl;

}

C++标程：
#include <iostream>
using namespace std;
int a[15];
int main()
{
int n,count=0;//count为累加器
for (int i=1;i<=10;i++)
cin>>a[i];//输入10个苹果🍎离地面的高度
cin>>n;//陶陶伸手最大高度
n+=30;//在加上板凳的高度，求出陶陶摘苹果最高的高度
for (int i=1;i<=10;i++)
if (n>=a[i]) count++;//如果够得到，就加1
cout<<count<<endl;
return 0;
}
