lua sum of array

To calculate the sum of an array in Lua, you can follow these steps:

1. Initialize a variable to hold the sum, let's call it "sum" and set it to 0.

2. Iterate through each element in the array using a loop. For each element, perform the following steps:

3. Add the current element to the sum variable. You can do this by using the "sum = sum + element" expression.

4. Repeat steps 2 and 3 for each element in the array.

5. Once the loop is completed, the sum variable will hold the total sum of the array.

Here is an example code snippet that demonstrates the calculation of the sum of an array in Lua:

-- Initialize the array
local array = {1, 2, 3, 4, 5}

-- Initialize the sum variable
local sum = 0

-- Iterate through each element in the array
for i = 1, #array do
   -- Add the current element to the sum
   sum = sum + array[i]
end

-- The sum of the array will be stored in the sum variable

Please note that in Lua, arrays are indexed starting from 1. In the example above, we assume that the array is already defined and contains numeric values. If your array contains elements of a different type, you may need to modify the code accordingly.
