Inline Function in C++

/*
Inline Function
===============

If You Make The Function as Inline then execution speed of
the function becomes higher compare to normal function.

If You Like To  Make a Function as Inline then you must not
include for loop,while loop,switch case and recursive
inside a function.

if you put any for or while inside a function,compiler
ignore inline and consider as a normal function.

defaultly all functions inside a class consider as a
inline function
