how to calculate the average of a student and then calculate the class average using "do while" and "for" in C #?

Question

I know that to calculate the average of each one is like this, but I do not know how to calculate the average of the class:

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
double notes, totalnotes = 0, average = 0;
int cont;

for (cont = 0; cont < 4; cont++)
{
Console.WriteLine("Insert the note: ", cont);
notes = Double.Parse(Console.ReadLine());
totalnotes += notes;
}

average = totalnotes / cont;
Console.WriteLine("Your average was: {0}", average);

}
}
}

Answer 1

So you want to calculate the results of a student and the result of the entire group (class is a confusing in this context) the student is in.

According to the assignment you should use a do while loop

A do while loop runs at least one time, and is evaluated at the end of the loop.

Do
{
Console.WriteLine("Press 'N' to enter the result of another student);
AnotherStudent = Console.ReadLine();
} While (AnotherStudent == 'N')

This is difficult to use in the sololearn playground because you need to put all inputs in before running the code.

The fun of average is that you can sum them, divede it by the number of students and have a new average.

So make a variable
totalaverage
and make a variable
totalstudents

Declare these variables above the do while.
if a average of a student is calculate
totalaverage += average;
also increate the number of students
totalstudents++;

When the do-while loop is finished.
Calculate the average of the group of students
Group_average = totalaverage / totalstudents

This is pseudo code, please make you own.

Answer 2

Please explain you question a bit more.
I can see you are calculating a average.
Where do you try to calculate the second average ?

Answer 3

Yes, using the first average
