Write every thing needed in function main for calling the above function.
v) discuss the 2 primary differences ranging from a pointer variable and reference variable.
vi)
a) A class has 1 data member and 1 method member. If we declare five objects of this class then the number of addresses for data member and method member are _________ and _______ respectively.
b) When an object of class is goes out of scope _______ is called automatically.
Long Questions- [7x2]
2) elaborate the characteristics of a friend function? Design two classes called husband and spouse having data member to represent their corresponding salary. Include methods to learn and display the salary of the corresponding classes. Include a member function in the spouse class called total_income() which display the total income of the family.
3) elaborate the difference ranging from constructor and destructor? Design a class called time having data members to represents hour, min and second. learn time in seconds using parameterized constructor, assign it to the corresponding data members after proper conversion and display them in hr: min: sec format.
