✏️ The if-statement causes a branch in the flow of a program's execution and the else-if idiom is used for multi-branches.
What happens when all branches depend on the same value of the expression?
That is when the switch statement comes in.

✏️ A switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution.

✏️ A switch statement starts with a variable called the switch vale. Each case indicates a possible value for this variable and the code that run if the variable matches the value.
✏️ Basic syntax.
✏️ Example.
n here is the switch value. if the value entered == 1,
case 1 is executed. if n == 2, then case 3 is executed.
If none matches the cases, then the default case will be executed.
