AIM:
A program to illustrate the use of difference operators to access the class member using friend function
ALGORITHM:
1) Start the process
2) Invoke the classes
3) Call the set_xy() first
a) Assign the value of x and y
b) Print the value of x and y
4) Call the sum() for second(friend)
a) Again assign the temp value of x and y
5) Print the value of x and [...]
CONSTRUCTOR AND DESTRUCTOR
AIM:
A program to print student details using constructor and destructor
ALGORITHAM:
1. Start the process
2. Invoke the classes
3. Call the read() function
a. Get the inputs name ,roll number and address
4. Call the display() function
a. Display the name,roll number,and address of the student
5. Stop the process
PROGRAM
#include<iostream.h>
#include<conio.h>
class stu
{
private: char name[20],add[20];

AIM:
A program to solve a quadratic equation, using OOP techniques.
ALGORITHM:
1) Start the process
2) Invoke the classes
3) Get the input for a,b,c;
4) Call the function getinfo() and display()
5) Check if a=0
a) True : compute c/b;
i) Print the value of a/c;
b) False: compute b*b-4*a*c;
i) If ( b*b-4*a*c)=0
ii) Call img();
iii) Otherwise : call real(a,b,c);
6) Stop the process

#include<iostream.h>
#include<conio.h>
class equation
{
private:float a,b,c;
