I need help inputting from text file help

[bknick24]

I need to set up a loop that will pull a set of data from a text file for example, wet.txt In the text file will contain high and low temperature data, as well as rain accumulations for an unknown amount of days, For example:

low high rain
30 60 0.3
25 55 0
30 65 0

I feel like i'm making this too complicated, I feel like I can put this into just one loop but i'm not sure how. I believe I would be using a while loop because we don't how many days of data their would be.

The output should look like:

Days reported = 3
Min Temp = 25
Max Temp = 65
Avg Low = 28.3
Avg High = 60.0
Total rain = 0.3
Number of rainy days = 1

How do I make this happen with the while loop I have? Also, how do I call the variables "fin" into this function

#include <fstream>
#include <iostream>

using namespace std;

int main()
{
    
    while( fin.good() )
{
    fin >> low >> high >> rain; 
}
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

declare a bunch of variables outside your while loop and increment/change them within the loop while you're reading, then do your averages outside the loop.

For example:

int main()
{
    ifstream fin("filename", ios::in);

    // Declare some variables here to increment/change in your loop
    int numDays = 0;
    int sumLow   = 0;
    ...
    while( fin.good() )
    {
        fin >> low >> high >> rain;
        ...
        sumLow += low;
        ++numDays;
    }

    // compute your averages and other stats here
    int avgLow = sumLow / numDays;
    ...
}
