The last type of functionality in this brief introduction is looping. Looping allows you to repeat the execution of code. Listing 1.12 is an example of a for loop. The for statement expects three parameters separated by semicolons. The first parameter is executed once before the loop begins. It usually initializes a variable. The second parameter makes a test. This is usually a test against the variable named in the first parameter. The third parameter is executed every time the end of the loop is reached (see Figure 1.5).
