Functions are groups of codes which can be written separately from main program and can be called anywhere in the program. When someone is called by his senior in any office to perform some work, in the same way a function is also called in the main program to perform a particular task.
By sorting, we simply mean to arrange items in a particular order. The items may be placed alphabetically, increasingly or decreasingly. The words can be arranged alphabetically whereas numbers can be arranged in increasing or decreasing order.
The switch case is an alternative of if…else statement which does almost the same thing. The switch case statement tests a variable against a series of values until it finds its match.
