Computer programming involves analyzing problems, designing algorithms, and implementing solutions as programs in a programming language. C is a widely used programming language that was originally developed for writing operating systems. C++ builds on C by adding object-oriented programming features like classes, inheritance, and templates. Both C and C++ are commonly used to develop systems software like operating systems and drivers due to their high performance.

2. Any Idea About Programming

3. Computer Programming
• Computer programming is a process that leads
from an original formulation of a computing
problem to executable computer programs.
• Programming involves activities such as analysis,
developing understanding, generating algorithms,
verification of requirements of algorithms
including their correctness and resources
consumption, and implementation of algorithms
in a target programming language.

4. Computer Programming
• Source code is written in one or more
programming languages.
• The purpose of programming is to find a
sequence of instructions that will automate
performing a specific task or solving a given
problem.
• The process of programming thus often requires
expertise in many different subjects, including
knowledge of the application domain, specialized
algorithms, and formal logic.

5. Programming Language
• A programming language is a vocabulary and set
of grammatical rules for instructing a computer
or computing device to perform specific tasks.
• The term programming language usually refers to
high-level languages, such as BASIC, C, C++,
COBOL, Java, FORTRAN, Ada, and Pascal.
• Each language has a unique set of keywords and a
special syntax for organizing program
instructions.

8. C++
• C is a computer programming language. That
means that you can use C to create lists of
instructions for a computer to follow.
• C belongs to the structured, procedural
paradigms of languages.
• It is proven, flexible and powerful and may be
used for a variety of different applications.
• Although high-level, C and assembly language
share many of the same attributes.
• C is one of thousands of programming languages
currently in use.

9. C++
• C is what is called a compiled language. This
means that once you write your C program,
you must run it through a C compiler to turn
your program into an executable that the
computer can run (execute).
• The C program is the human-readable form,
while the executable that comes out of the
compiler is the machine-readable and
executable form.

10. C Language History
• The C programming language is a structure
oriented programming language, developed at
Bell Laboratories in 1972 by Dennis Ritchie.
• C programming language features were
derived from an earlier language called “B”
(Basic Combined Programming Language –
BCPL).
• C language was invented for implementing
UNIX operating system.

11. C Language History
• In 1978, Dennis Ritchie and Brian Kernighan
published the first edition “The C Programming
Language” and commonly known as K&R C
• In 1983, the American National Standards
Institute (ANSI) established a committee to
provide a modern, comprehensive definition of C.
The resulting definition, the ANSI standard, or
“ANSI C”, was completed late 1988.

12. Some of C's most important features
include
• Fixed number of keywords, including a set of
control primitives, such as if, for, while, switch
and do while
• Multiple logical and mathematical operators,
including bit manipulators
• Multiple assignments may be applied in a single
statement.
• Function return values are not always required
and may be ignored if unneeded.
• Typing is static. All data has type but may be
implicitly converted.

13. USES OF C PROGRAMMING
LANGUAGE
• The C programming language is used for
developing system applications that forms a
major portion of operating systems such as
Windows, UNIX and Linux.

14. Below are some examples of C being
used
• Database systems
• Graphics packages
• Word processors
• Spreadsheets
• Operating system development
• Compilers and Assemblers
• Network drivers
• Interpreters

15. Advantages of C Language
1. C language is a building block for many other currently
known languages. C language has variety of data types
and powerful operators. Due to this, programs written in
C language are efficient, fast and easy to understand.
2. C is highly portable language. This means that C
programs written for one computer can easily run on
another computer without any change or by doing a
little change.
3. There are only 32 keywords in ANSI C and its strength lies
in its built-in functions. Several standard functions are
available which can be used for developing programs.

16. Advantages of C Language
4. Another important advantage of C is its ability to extend
itself. A C program is basically a collection of functions that
are supported by the C library this makes us easier to add
our own functions to C library. Due to the availability of
large number of functions, the programming task becomes
simple.
5. C language is a structured programming language. This
makes user to think of a problem in terms of function
modules or blocks. Collection of these modules makes a
complete program. This modular structure makes program
debugging, testing and maintenance easier.

17. Disadvantages of C Language
1. C does not have concept of OOPs, that’s why
C++ is developed.
2. There is no runtime checking in C language.
3. There is no strict type checking. For example,
we can pass an integer value.
4. for the floating data type.

18. Disadvantages of C Language
5. C doesn’t have the concept of namespace.
6. C doesn’t have the concept of constructor or
destructor.
