When does ambiguity arise in multiple inheritance? How can one resolve it? Develop a program in C++ to create a derived class having the following items, name, age, rollno, marks, employee id and designation. Design a base class having data members rollno, marks and another base class is employee having data members name, age and designation. These both base classes are inherited from a single base class person with data members name and age. The program should carry out the required input and output (member function for all.

What is Operator overloading? Design a Distance class with data members to store distance in meters, centimeters, and millimeters. Write a program to overload addition and subtraction operators respectively on Distance class objects. Here both base classes are inherited from a single base class person with data members name and age. The program should carry out the required input and output (member function for all.

Explain the role of constructor and destructor in a class. Write the appropriate syntax for the copy constructor and parameterized constructors. What is Constructor? A constructor of the various overloaded constructors in C++ is a special type of member function of a class that is invoked automatically whenever an object of that class is created. It is used to initialize the data members of the object and to perform other necessary operations. A constructor has the same name as the class and does not have any return type. There are mainly three types of constructors in C++: 1. Default Constructor 2. Parameterized Constructor 3. Copy Constructor Example: class Complex { private: int real; int imag; public: Complex() { // Default constructor real = 0; imag = 0; } Complex(int r, int i) { // Parameterized constructor real = r; imag = i; } Complex(const Complex &c) { // Copy constructor real = c.real; imag = c.imag; } };
