For Loops
for loops are the most concise loop construct.There syntax is highly resemblant of their C counterpart:
for (var i := 0; i < 5; i++) {
print "i is: #{i}"
}
The syntax of the
for loop is:for (<initalization>; <condition>; <afterthought>) {
[code block]
}
Essentially the way this works is:
execute initalization
while condition evaluates to true
execute code block
execute afterthought
The output of the first
for example would be:i is: 0
i is: 1
i is: 2
i is: 3
i is: 4
i is: 5
This is because the variable
i is initialized to 0 at the beginning. Then, because i is less then 5, it will keep running the code block until i is not less than 5. This happens because the i++ increases i everytime, after, the code block (i.e. the print) is executed.Last modified 3yr ago
