Standard
C++
doesn't
have
a constant for
PI
. Many
C++
compilers define M_PI in cmath (or in math. h for C) as a non-standard extension. You may
have
to #define _USE_MATH_DEFINES before you can see it.

#define

Here, #define is a pre-processor directive. It is used to define something, like here we have defined that
PI
is 3.14. So, before going to the compiler, if '
PI
' comes anywhere in the
program
, it will be replaced by 3.14.
