if(a[i]<x)

改成

if(x>=a[i])

对，题目说是碰到，不是超过

第11行应改为a[i]<=x才对

@kanqiqin 过了

#include<iostream>
using namespace std;
int main(){
    long long a[12]={0},x,sum=0;
    for(int i=0;i<10;i++){
        cin>>a[i];
    }
    cin>>x;
    x+=30;
    for(int i=0;i<10;i++){
        if(a[i]<=x){
            sum++;
        }
    }
    cout<<sum;
    return 0;
}
