Switch Case Statement

Switch Case Statement is a type of selection control statement that exists in most modern imperative programming languages (e.g., Pascal, C, C++, C#, and Java). Its purpose is to allow the value of a variable or expression to control the flow of program execution via a multiway branch (or "goto", one of several labels). The main reasons for using a switch include improving clarity, by reducing otherwise repetitive coding, and (if the heuristics permit), offering the potential of faster execution through compiler optimization. In some programming languages, a statement that is syntactically different but conceptually the same as the switch statement is known as a case statement, select statement or inspect instruction.
