头歌里为什么报ch5/ch6/source/sy506.c:1:9: fatal error: iostream: No such file or directory

#include<iostream>
using namespace std;

int sum(int n)
{
    int sum = 0;
    for (int i = 1; i <= n; i++)
    {
        sum = sum + i;
    }
    return sum;
}

    cout << "请输入n:";
    cin >> n;
  
    cout << sum(n);
   
    return 0;
}
