Functions

Types of functions:
There are 2 types of functions namely,

1. Built - in 
2, User defined

Built-in functions are defined by developer of the language and are available in your program implicitly. To make use of Built-in  function then the corresponding header file must be included.
For example :
to make use of pow() function one must include #include
Otherwise error message explaining "Error: Function prototype for this function is not defined"

User Defined function(UDF) : These function are defined by user. This chapter is about defining User Defined function

In the next post we will see about categories of functions in UDF.
