# lua calculate average number

To calculate the average number in Lua, you can follow these steps:

Initialize the sum variable to 0 and the count variable to 0. These variables will be used to keep track of the sum of the numbers and the number of values entered, respectively.

Use a loop to prompt the user to enter numbers. You can use the io.read() function to read input from the user. Inside the loop, add the entered number to the sum variable and increment the count variable by 1.

After the loop ends, calculate the average by dividing the sum by the count. Store the result in a variable called average.

Finally, print the average to the console using the print() function.

Here's an example code snippet that demonstrates the calculation of the average number in Lua:

```
local sum = 0
local count = 0
while true do
print("Enter a number (or 'q' to quit):")
local input = io.read()
if input == "q" then
break
end
local number = tonumber(input)
if number then
sum = sum + number
count = count + 1
else
print("Invalid input. Please enter a number.")
end
end
if count > 0 then
local average = sum / count
print("The average is: " .. average)
else
print("No numbers entered.")
end
```

I hope this explanation helps you understand how to calculate the average number in Lua.
