Repeating Actions
Iteration means repetition. Imagine writing "I will not be late" 100 times - boring! A loop does it for you. FOR loops repeat a set number of times (write it 100 times). WHILE loops repeat while a condition is true (keep writing until the teacher says stop). DO-WHILE always runs at least once before checking. Loops are the power tools of programming!
