how to make a reverse half pyramid pattern on c++ using for loops

pattern image

this is the code I've tried but it gives out a full triangle instead

#include<iostream>
using namespace std;
int main()
{int n;
cin>>n;
for(int i=1;i<=n;i++){
    for(int j=1;j<=n;j++){
     if(j<=n-i)
    { cout<<" ";}
    else
    {
        cout<<"*";
    }
    } cout<<endl;
}
}
