1. Q1. The C programming language was originally developed by Dennis Ritchie at Bell Laboratories in which year?

   • A. 1972
   • B. 1969
   • C. 1983
   • D. 1978
   Solution

   Dennis Ritchie developed C at Bell Labs in 1972, evolving it from the earlier B language.

2. Q2. Who authored the original C++ language, developed at Bell Laboratories, which was initially called 'C with Classes'?

   • A. Dennis Ritchie
   • B. Bjarne Stroustrup
   • C. James Gosling
   • D. Ken Thompson
   Solution

   Bjarne Stroustrup developed C++ at Bell Laboratories beginning in 1979, originally naming it 'C with Classes' before it was renamed C++ in 1983.

3. Q3. In C++, which access specifier makes class members accessible within the class and to its derived classes, but not to objects outside the class hierarchy?

   • A. friend
   • B. private
   • C. public
   • D. protected
   Solution

   The 'protected' specifier allows access within the class itself and in derived classes, but not through objects of the class externally. 'private' blocks derived classes, and 'public' allows outside access.

4. Q4. Which one of the following is NOT a storage class in C?

   • A. auto
   • B. static
   • C. volatile
   • D. register
   Solution

   The four storage classes in C are auto, register, static and extern. 'volatile' is a type qualifier, not a storage class.

5. Q5. Arrange the following ISO C++ language standards in correct chronological order of publication, from earliest to latest.

   • A. C++03, C++98, C++14, C++11
   • B. C++98, C++03, C++11, C++14
   • C. C++03, C++98, C++11, C++14
   • D. C++98, C++11, C++03, C++14
   Solution

   The first ISO C++ standard was C++98 (1998), followed by the C++03 (2003) corrigendum, then the major C++11 (2011) revision, and C++14 (2014).
