list = {"One", "Two", "Three", "Four", "Five", "Six"}
---------- For loop -----------
print("Counting from one to three:")
for element = 1, 3 do
print(element, list[element])
end
print("Counting from one to four, in steps of two:")
for element = 1, 4, 2 do
print(element, list[element])
end
The numeric for loop repeats a block of code while a control variable runs through an arithmetic progression.
Output:
Counting from one to three:
1 One
2 Two
3 Three
Counting from one to four, in steps of two:
1 One
3 Three
days = {"Sunday",
"Monday", "Tuesday",
"Wednesday", "Thursday",
"Friday", "Saturday"}
for i, v in ipairs(days) do
print(days[i], i, v)
end
The generic for statement works by using functions called iterators. On each iteration, the iterator function is
called to produce a new value, stopping when this new value is nil.
Output:
Sunday 1 Sunday
Monday 2 Monday
Tuesday 3 Tuesday
Wednesday 4 Wednesday
Thursday 5 Thursday
Friday 6 Friday
Saturday 7 Saturday
