How do I determine the highest and lowest values from a text file?

[iwasherenotyou]

For part of my assignment I have to do what the title says. Here's the file's contents.

95
100
120
130
135
145
155
185
190
160
130
120

What exactly do I have to do to be able to determine my highest and lowest values? I'll post what I've written so far if needed.

#include <iostream>
#include <fstream>
#include <limits>
using namespace std;

int main()
{
    int low = numeric_limits<int>::max();
    int high = numeric_limits<int>::min();

    ifstream fin("text.txt");

    if(!fin)
        return 1;

    int n;
    while(fin >> n)
    {
        if(n > high)
            high = n;
        if(n < low)
            low = n;
    }

    cout << "Low: " << low << " High: " << high << '\n';
}
