2. Why need Programming Language?
 As we all know that the computer understand only zeros and ones but humans cannot
understand codes written in form of zeros and ones.
 So we need programming language that is understandable to humans also.
 A computer programming language helps in automating the task which are time consuming,
error prone, repetitive and not person dependent etc.
 Programming languages also help in reorganize the processes, provide better experience as
well as keeping track of historical data, analysing data etc.

3. History of C language
 C is a general purpose language which is very closely related with Unix for which it was
developed in Bell Labs.
 Most programs of Unix are written and run with the help of c.
 In 1972, Dennis Ritchie developed the C language at AT and Bell laboratories.
 Before C language, Ken Thompson developed a B language which was influenced by a basic
combined programming language i.e. BCPL by Martin Richards.
 Dennis Ritchie made number of advancements in B language new language called C language
is developed.

4. Why ‘C’ given this name?
 Many ideas of C language were derived and taken from 'B' language.
 BCPL and CPL are previous versions of 'B' language.
 As many features came from B So, it was named as 'C'.

6. More about ‘C’
 case sensitive language.
 can be used to develop operating systems.
 also known as middle level language.
 can be used to access the processor registers.
 programs are easy to debug.
Note: These all are also called features or characteristics of C Language.
