C About & History
1. Who is the father of Programming Language C?
A. Ada Lovelace
B. Dennis Ritchie
C. Tim Berners-Lee
D. Alan Turing
Ans : B
Explanation: C programming language was developed by Dennis Ritchie in 1972 at the Bell Laboratories of the AT & T that is located in U.S.A. So we call Dennis Ritchie is the founder of c language. .
2. where was the c language developed ?
A. Stanford Lab
B. MIT Lab
C. Harvard University
D. AT & T Bell Laboratory
Ans : A
Explanation: The C programming language was developed at AT & T Bell laboratories during 1970-72s
3. Many features of C were derived from which language ?
A. PASCAL
B. B
C. BASIC
D. FORTRAN
Ans : B
Explanation: Richie and Thompson wanted to rewrite the operating system in B, a language they had previously developed, but B were type worthy, and therefore mixed bits / words were not well suited for address and PDP-11 type . B was a simplified version of Thompson’s BCPL, which was more ALGOL than the language.
4. What is C language?
A. C language is a structure/procedure oriented
B. C language is a middle level programming language
C. C language was invented for implementing UNIX operating system
D. All of the above
Ans : D
Explanation: C language is just a high level computer language. High level languages help Human beings to express Logic. Computers dont understand this language. So, you need a mediator. This mediator is usually a Compiler or Interpreter. In case of C, we have a compiler. The compiler translates the logic expressed in C into Machine Code which is the language of computers.
