Question

I’m new to C#, well, coding in general.
I have done fairly well by myself to date, in this introduction course I am taking, but I ran into a road bump.

I am trying to figure out how to code a if statement that will run inside a loop to analyze 5 different ints as they are entered and to put the max int and min int seperatly so that I can ue the remaining three ints to make a calculation.
To be exact, validate user input and remove the min/max user input to average the remaining three.

PS, I tried an array but for some reason it wasn’t working well. I don’t have the code as I’m at work right now though. I was told in a lecture that an if statement should be used but arrays are possible too.

Thank you for your time and any possible answers.

Not sure about your question… You want to know, the max and min about 5 values, and the avarage about the three others…

int[] n = { 4, 7, 29, 3, 87 };
int max = 0;
int min = int.MaxValue;
double avg = 0;

foreach (int i in n)
{
    if (i > max)
        max = i;

    if (i < min)
       min = i;

   avg += i;
}

avg = avg / n.Count - 2;
