Object Oriented Programming Practical 19 Question 1 Overload the unary operator –(minus) using member function and friend function unary.cpp C #include<iostream.h> #include<conio.h> class unary { float num; public: void accept() { cout<<"nEnter number: "; cin>>num; } void display() { cout<<"Number= "<<num<<endl; } unary operator–() { num=num-1; } }; void main() { clrscr(); unary u; u.accept();

Object Oriented Programming Practical 18 Question 1 Write a C++ Program to interchange the values of two int , float and char using function overloading. swap.cpp C #include<iostream.h> #include<conio.h> void swap(int a,int b) { int temp=a; a=b; b=temp; cout<<"nAfter swapping number1 is "<<a<<" and number2 is "<<b<<endl; } void swap(float a,float b) { float temp=a;

Object Oriented Programming Practical 17 Question 1 Write a C++ program declare a class “polygon” having data members width and height. Derive classes “rectangle” and “triangle” from “polygon” having area() as a member function. Calculate area of triangle and rectangle using pointer to derived class object. polygon.cpp C #include<iostream.h> #include<conio.h> class polygon { public: int
