3. LANGUAGE
•The source of communication between two entities
is called language.
COMPUTER LANGUAGES:
•There are three types of language used.
1) HIGH LEVEL LANGUAGE:
The language which can easily
understandable by humans is called high level
language.

4. COMPUTER LANGUAGES
2) MIDDLE LEVEL LANGUAGE:
The language which can
understandable by both human and machine is called
middle level language.
3) LOW LEVEL LANGUAGE:
The language that can easily
understandable by machine is called low level

5. WHAT IS C?
•C is high level programming language developed by
Dennis Ritche in 1972 at TB/ Tbell laboratories.
•C is powerful, flexible, efficient, modular, compiled,
and general purpose programming language.
•C is use for any programming tasks.
•C is used to develop high level application
programs. ie. Banks, Applications, Scientific research

6. FEATURES OF C LANGUAGE
•C language is simple reliable and easy to use
•It is high level language with efficiency of assembly
language.
•It support user defined data types for great
flexibility in programming.
•It support rich library functions.
•It supports pointer with pointer operations to access

7. C++ PROGRAMMING LANGUAGE
• C++ developed by Bjarne stroustrup in 1982.
• It is high level programming language.
• It is reliable , clear and unambiguous.
• It is easy and give verification for correction.
• It is easy and understandable by Human.
• It is powerful language.
• It consist of Rich Library Functions.
#include <iostream.h>
#include <conio.h>

8. FEATURES OF C++ PROGRAMMING
• C++ is the superset of C, therefore any legal C program is a legal
C++ program, although reverse is not possible.
• C++ is an Object Oriented version of C programming involves
concepts that are new to programmers of traditional languages
such as BASIC (Beginner's all purpose symbolic Instruction Code), Pascal and C.
• It is clear, more reliable and more easily maintained programs.
• As compare to C, C++ has many features like improved approach
to input/output and a new way to write comments /* Hi every one
*/.
