 Chapter 4Control Structures are blocks of code that force the computer to make a decision. Sometimes you will want your program to perform different tasks depending on certain boolean conditions. For example if you were writing a game you would probably find it very useful to be able to know when the user has won the game so that you could show a high scores page. If control structures were not used then programs would begin at the first line and excecute every line of code in order, giving the same output every time. Imagine how boring Tetris would be if there was only one piece! Control structures allow you to change the order of execution, jumping from one section of code to another as needed. | ||
