Calculating minimum, maximum, and average of inputted numbers

Question

Is there a way to calculate the average/min/max of all numbers without using an array? Need to calculate up to 10,000 numbers per sec.

Answer 1

You don't really need to store any numbers in an array to find the average/min/max, as you are iterating through the numbers you do

if(currentSmallest > currentNumber)
     currentSmallest = currentNumber

if(currentLargest < currentNumber)
     currentLargest = currentNumber

and in addition you will keep a counter and the total sum, and by dividing those numbers you will get the average. No need to store them in an array.
