Describe the basic structure of a C++ program with all necessary blocks.

Differentiate Object Oriented Programming (OOP) and Procedure Oriented Programming (POP).

Write a C++ program to find out the sum and average of three numbers using nesting of member function.

Write a C++ program to find volume of cube, cylinder and rectangular box using concepts of function overloading. (volume of cube = s3, volume of cylinder is π*r2*h, volume of rectangular box is l*b*h)

When can you make function inline? What are the advantages of making function inline?

Following is a main() program. void main() { time T1; int duration = 85; T1 = duration; } Where time is a class which contains variables hrs and minutes. duration stores total time in minutes. Define a class time with necessary functions to break up the duration in maximum hours and remaining minutes and store them into hrs and minutes respectively.

Write a C++ program that overloads + operator to add two complex numbers.

Consider following class declarations. class ABC; class XYZ{ int x; public: void get_x(int i) {x=i;} friend void sum(XYZ,ABC); }; class ABC{ int y; public: void get_y(int i) {y=i;} friend void sum(XYZ,ABC); }; By considering above class declarations, define a function sum() at outside the class to find out the sum of x and y and display the result. Also define the main() which satisfy above class declarations.
