Summary
In this chapter we introduced the concept of loops. Loops enable us to repeat a certain block of code. We need some sort of condition when we loop, and as long as that condition is true, we'll keep looping. As soon as it changes to false, we end our loop.
We have seen the while loop, in which we just insert a condition, and as long as that condition is true we keep looping. If the condition is never true, we won't even execute the loop code once.
This is different for the do while loop. We always execute the code once, and then we start to check a condition. If this condition is true, we execute the code again and do so until the condition becomes false. This can be useful when working with input from outside, such as user input. We would need to request it once, and then we can keep on requesting it again until it is valid.
Then we saw the for loop, which has a slightly different syntax. We have to specify a variable, check a condition (preferably using...
