Introduction to Programming

What is Programming???
To tell the computer what to do is known as Programming..

It is the simplest definition of programming.. Through programming we convey our massage to computer in his language.
We all know that computer is a machine and it does not has a brain .It only understand the binary language (0 or 1) only..
Types of programming languages:
There are two main types of programming languages
         High level language
         Low level language
High level language:

              The language which is only understandable by Human machine but not by computer.

For example:
      C++, C, Java etc.

Low level language:

            The language which is only understandable by computer.

For example:
             Machine Language

What is Integrated Development Environment (IDE)???
An integrated development environment (IDE) is a programming environment that has been packaged as an application program, typically consisting of a code editor, a compiler a debugger, and a graphical user interface builder. The IDE may be a standalone application or may be included as part of one or more existing and compatible applications. The basic programming language, for example, can be used within Microsoft Office applications, which makes it possible to write a WordBasic program within the Microsoft Word application. IDEs provide a user-friendly framework for many modern programming languages, such as C,C++.

Editor:

              Part of IDE were source code can be written..

Compiler:

              Part of IDE which convert  Source code into Assembly Language

Linker:

              Part of IDE which connects Source Code with the Header Files..

Assembler:

              Part of IDE which convert Assembly Language into Machine Language

Loader:

              Part of IDE which Loads The compiled code on Memory

Debugger:

               Pat of IDE which is Helpful in finding LOGICAL errors

                                       An IDE works as follow

                     

First we write code in editor,After writing code compiler in IDE compile it. After compile it change it into assembly language, after Assembly language it is further changed into to Machine language.   

Types of Errors In source code:

1. Logic Errors
2. Syntax Errors

What is Logical Error???

• 1.    Based on Poor logic of Program
• 2.    Compiled Successfully And produce wrong Result
• 3.    Difficult to DETECT and Remove
• 4    Debugger is Helpful in finding Logical Errors

What is Syntax Error???

• 1.    Base on any Error in the Source Code
• 2.    Program does not Compile
• 3.    Easy to Detect
• 4.    Easily Removable
