Introduction to Programming

Definition:

• Creating a sequence of instructions to enable the computer to do something.
• A sequence of instructions, stored in any medium that can be interpreted and executed by a computer.
• Computer programming is a process that leads from an original formulation of a computing problem to executable program.

Types of Programming:

1) Low Level Language

• ASSEMBLY
• TASM
• MASM

2) High Level Language

• C[Linux, Objective C, MS C, Turbo C, CSS, Borland C ]
• Cobol, Fortan, Ruby, Pascal, Python, GW Basic, C++, C#, Java etc.

 Technical divisions of the languages:

1) Procedural/Modular/Structure/Functional (1970-1992)

     Conceptually these divisions describe functions only.

     Procedural Language: C, GW Basic, Cobol, Fortan, Pascal, etc.

Ex: Example of bank that helps to understand what exactly Procedural/Modular/Structural/Functional language depend on:

In this example customer perform bank operations but procedural language doesn't care about what customer is or where to perform operations, it just depend on function (cash deposited, transactions, withdraw).

NOTE: Procedural is a standard word among Modular/Structural/Functional.

2) Object Based (1992-1998)

     object based language are those totally depend on object, class, inheritance.

• Microsoft Visual Basic 6.0
•   Lotus Notes 

3) Object Oriented (1998 - Continue)

     Object oriented language are those languages those completely follow the pillars of object   oriented programming (OOP).

• C++, Python, C#, Java, VB.NET, J# etc.
