Your email address will not be published. Using Function. Using for loop, we will traverse inputArray from array index 0 to N-1. average = total / 5. Average = Total Sum / Total no. The user can enter integer or floating point numbers therefore to store those five numbers we will use float or double type variables. This is stored in the variable n. If the user enters a value of n above 100 or below 100, a while loop is executed which asks the user to enter a value of n until it is between 1 and 100. It takes the input from the user on how many numbers have to get the average; Then, it takes the input of those numbers. How to Calculate Average Using Arrays?
