Q) what about Programming methodologies ?

There are two styles or approaches or methodologies of problem solving

1) Procedural oriented

2) Object oriented

Methodology is organizing the code. Style of the programming is the methodology.

To solve the problem language is required.

It is a tool to implement the features offered by the methodology solving the problem.

2 approaches to solve /implement the problem.

The total organizing principle is the methodology.  To implement methodology the language is required. Language is a tool.

Ex :

c++ is the tool to implement oop

Java  is the tool to implement oop

But these way of implementation is different to implement oop.

Old methodology contain 2 problems

1)      drawbacks  and

2)      productivity

so that's why new methodology(i.e, oop) is introduced.

Procedure oriented two types

1) Structured

2) Unstructured

Basically procedure oriented is super set of structured. So procedure oriented and procedure oriented is same.
