Unit – I

Q. two (a) discuss every of the operators that are available in C++ but not in C. 5
(b) How object oriented paradigm differ from procedural programming paradigm?
Explain. 5

Q. three (a) How inputs and outputs are taken/ displayed in C++? Differentiate ranging from
the input/output operators in C++ and the input/output functions used in C. 5
