Oops function (part 1)

Functions :

Function is the block of code which is used to perform a particular operation.

There are two type of the functions :

          (i)  Pre-defined functions

          (ii) User -defined functions .

Monolithic Programming : In this case , we write the entire logic in the single program.

The disadvantages of the monolithic programming are,

                   (a) Difficult to understand.

                   (b) Difficult to modify

                   (c) Difficult of debug.

    [Bug means computer program error and debugging is the process of locating and removing the computer program error.]

 Modular Programming : In the case of the modular programming , we divide the entire complex program into the simple sub-programs or modules.These modules are also known as functions.
