Switch

The Switch statement.

The switch statement, is a replacement for if-else statements. The switch statement reduces the numerous if-else statement that might occur in large apps. In a switch statement, there are two compulsory parameters: case and default. The case replaces the if-else statement and the default represents the final else statement. Let's glance through an example so as to better explain the syntax:

display "input your number : " read n 

switch (n) 
	case 2
		display "it is two"
	case 3 
		display "it is three"
	default
		display "i dont know but it "+n
end 

The above code example, displays it is two if the inputed value enclosed in n is 2 else displays it is three if the inputed value is 3 else returns a default message: I don't know but it's " +n.

If you observe, the above example can be re-written using the if-else syntax.

Use cases.

The switch statement is useful in deciding large datas. It can be used for building programs like grading systems etc. The switch statement serves as a better alternative to -if-elif-elsestatements. It is recommended and advised to use theswitch` statements when building complex / large apps.

Note that a default statement is required in a switch statement and the switch statement should be ended with qn end keyword.
