Each test will proceed to the next one until a true test is encountered. When a true test is found, its associated block of code is run, and the program then skips to the line following the entire if/else construction. If no test proves to be true, the default else block is executed, if one is present, and sets the default behavior.
Note that an else if block may be used with or without a terminating else block and vice versa. An unlimited number of such else if branches is allowed.
