2. In programming,
a switch, case, select or inspect stateme
nt is a type of selection control
mechanism that exists in
most imperative
programminglanguages such
as Pascal, Ada, C/C++, C#, Java, and so
on. It is also included in several other
types of languages. 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
theheuristics permit) also offering the
potential for faster execution through
easiercompiler optimization in many
cases.

programming language
construction that
allows the programmer
to instruct the
computer to perform a
certain instruction, or
set of instructions over
and over again.
