In programming, there are 3 important types of control flow structures.
Most programming languages support these kinds of structures. If you can master them, your solutions will become much more powerful.
In the previous unit, you've learned the conditional branch structure. This unit leads you to explore the wonderful world of loops.
Let's face it -- repeating the same thing over and over again is BORING! This is when loops come handy because computers excel at helping us with repetitive tasks.
Indeed, loops will save us a lot of typing! :)
