Lua - Take Multiple inputs

Question

I want to write a program that calculate the Average of all input numbers.

First it will asks "How many number you want to input" If users type 5 then the program will take 5 inputs Then it calculates the Average of it.

I wrote a function that takes passed numbers & returns average of of it But How do we ask the user to input multiple inputs and save it in array

Answer 1

local num = nil;

local sum = 0;

local n = 0;

while num != 0 do
    num = io.read()
    sum = sum + tonumber(num)
    n = n + 1;
end

print(sum / (n-1))

this code will calculate all inputs and will stop asking for input until the user types 0, when he types 0, he will print the average of the values entered
