1.	Why references are different from pointers?(a) A reference cannot be made null(b) A reference cannot be changed once initialized(c) No extra operator is needed for dereferencing of a reference(d) All of the mentionedThis question was addressed to me during a job interview.My doubt stems from OOPs Concept topic in division Basics Concepts of C++ of C++
