Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

Construct 2.1.2: Multi-branch if-else statement. Only 1 branch will execute.

if (expression1) {
// Statements that execute when expression1 is true
// (first branch)
Multi-branch if-else statements
An If-else statement can be extended to have three (or more) branches. Each branch's expression is checked in sequence. As soon as one
branch's expression is found to be true, that branch's statement execute (and no subsequent branch is considered). If no expression is true,
the else branch executes.
