C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972.
– Easy to learn
– Structured language
– It produces efficient programs
– It can handle low-level activities
– It can be compiled on a variety of computer platforms
Why Use C?
C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C:
– Operating Systems
– Language Compilers
– Text Editors
– Print Spoolers
– Network Drivers
– Modern Programs
– Language Interpreters
Applications of ‘c’
– C programming language can be used to design different types of application like designing the system software like OS & compiler.
– Designing the application software like database & spread sheets.
– To design the graphics related applications i.e. pc’s and mobile games.
– To evaluate the mathematical equations.
Features Of C Programming Language
C language is one of the powerful language. Below are some of the features of C language.
– Efficiency and Effectiveness
C is the most popular programming language which has many advantages:
Middle level language:
As a middle level language C combines both the advantages of low level and high level languages. (arrays,pointers etc).
General purpose programming language:
C can be used to implement any kind of applications such as math’s oriented, graphics, business oriented applications.
We can compile or execute C program in any operating system(unix,dos,windows).
Powerful programming language:
C is very efficient and powerful programming language, it is best used for data structures and designing system software. C is case sensitive language.
Advantages Of C
C Language has list of advantages due to this it is very much popular language around the world and best suitable for the programmer to learn at the first stage of the programming.
– Procedure Oriented Language
C Language is procedure oriented language, here user creates procedures or functions to execute their task. Procedure oriented language is very much easy to learn because it follows algorithm to execute your statements. To develop program using procedure oriented language, you need to draw/prepare algorithm and then start converting it into procedure or functions.
– Lots of Libraries
C Language provides lots of functions which consist of system generated functions and user defined functions. C Compiler comes with list of header files which consist of many general functions which can be used to develop program, while programmer can also create function as per their requirements that is called as user generated/defined function.
– Speed of Compilation
C compiler produces machine code very fast compared to other language compiler. C compiler can compile around 1000 lines of code in a seconds or two. One more benefit of the C Compiler is that it also optimize the code for faster execution.
– Easy to Learn
C Language syntax is very easy to understand. It uses keyword like if, else, goto, switch, main, etc. This kind of keyword we all are using in our day to day life to convey meaning or to get some decisions.
C Language setup is around 3-5 MB. So you can carry this language in your Floppy Drive or Pen Drive. It is very easy to install and operate, Again its output is exe file which can be executed in any computer without any other framework / software.
Disadvantages Of C
C Language has also some disadvantages. C Language does not have major disadvantages but some features is missing in the C Language, obviously that’s why C Language is very much powerful now.
– Object Oriented Programming Features (OOPS)
Object Oriented Programming Features is missing in C Language, You have to develop your program using procedure oriented language only.
– Run Time Type Checking is Not Available
In C Language there is no provision for run time type checking, for example i am passing float value while receiving parameter is of integer type then value will be changed, it will not give any kind of error message.
– Namespace Feature
C does not provides namespace features, so you can’t able to use the same variable name again in one scope. If namespace features is available then you can able to reuse the same variable name.
– Constructor and Destructor is not available
C does not provide object oriented features, so it don’t have Constructor and Destructor features. Constructor and Destructor is used to construct object and destroy object. So in C Language you have to implement manually construction and destruction of the variable using function or by other means.
