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. Jeevanopadhihttp://Jeevanopadhi.com provides c language with training and certification with best certified tutors.
C in computer language:
C is a particularly popular language for personal computer programmers because it is relatively small — it requires less memory than other languages. The first major program written in C was the UNIX operating system, and for many years C was considered to be inextricably linked with UNIX.
In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard.
The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C.
C has now become a widely used professional language for various reasons
- 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
C was initially used for system development work, in particular the programs that make-up the operating system.
Why use C?
Mainly because it produces code that runs nearly as fast as code written in assembly language.
Some examples of the use of C might be:
- Operating Systems
- Language Compilers
- Assemblers
- Text Editors
- Print Spoolers
- Network Drivers
- Modern Programs
- Data Bases
- Language Interpreters
- Utilities
Difference between c and c++
The major difference between C and C++ is that C is a procedural programming language and does not support classes and objects, while C++ is a combination of both procedural and object oriented programming language; therefore C++ can be called a hybrid language.
