In Lua, we can change all the elements of an array using a loop. Here's an example code snippet that uses a for-loop to change every element of an array:
-- Creating an array with some initial values
array = {1, 2, 3, 4, 5}
-- Loop to change each element of the array
for i = 1, #array do
array[i] = array[i] * 2 -- doubling each element of the array
end
-- Printing the updated array
for i = 1, #array do
print(array[i])
end
Output:
2
4
6
8
10
In the example above, we created an array with some initial values and then used a for loop to iterate through each element of the array and doubled each element. Finally, we printed the updated array using another for loop.
Similarly, we can use any kind of operations or functions inside the loop to change all elements of the array according to our needs.
