Making a simple calculator using switch statement

Asalam o Alikum. I hope you all are fine by the grace of Allah Almighty.

Today I am here with another program that will help you to make a simple arithmetic calculator using switch statement.

Actually switch statement is a good alternative of “if-else-if” or nested if-else. It is very useful in a condition when there are many choices available and only one should be executed.Its syntax is as follows:

Syntax

switch(expression)

{

case 1:

statements;

break;

case 2:

statements;

break;

.

.

default:

statements;

}

Below is the source code of the above mentioned program:

Explanation:

               In this program,the result of a single expression is compared with multiple cases.If it matches with a certain case,the statement(s) below that case is executed.After execution,it comes out of the "switch" body due to "break" statement.This is actually the logic of this program.
