PROGRAMMING LANGUAGES

       Programming languages are  designed to communicate instructions to a computer.  A computer programming language is used to write programs that involves a computer to perform operations like computation or any logical operations.Programming languages are classified into :

           Low level languages

           High  level languages

Low level language:

      Low level languages can perform only primitive operations of the computers. Programs written in these languages are written according to the availability of memory and registers. Computer architecture is different to one another, so each type of computer there is a separate low level language. Programs written in on platform of computer cannot be ported to another .

Examples of Low level languages are:

Machine language:

       Programs written in these language, computation is based on binary numbers. Machine directly understands this language , so programs written in this language are directly executable without any translations. This makes program execution very fast. Machine languages are also called as First Generation Language.

Assembly language:

        Assembly language is similar to the machine language but they are much easier to programming because they allow programmer to substitute names for numbers. Assembly language consists of only numbers. Programs written in assembly language requires a translator. This translator is called as Assembler

High level language:

      High level language is similar to English. High level language uses natural language. These languages required translators for execution ( compilers, interpreters). Programs written in this language can be ported to any computer. The early high level languages are COBOL, BASIC, APL, etc.

      This language enables us to write programs in English words and familiar mathematical symbols which makes us easier to code a program.

C Programming Language:

        C programming language is a general purpose language  developed by Dennis Ritchie at  AT&T Bell Laboratories in 1972 for the use with the UNIX operating system.  C is most popular language which is widely used by programmers because of its rich features. C is designed to develop for implementing system software, but it is also widely used to develop  portable application software.
