MULTIPLE INHERITANCES
AIM:
Write a program to illustrating how all the three classes are implemented in multiple inheritance mode
ALGORITHM
• Start the process
• Invoke the class M
• Invoke the another class N
• Invoke one more class,ie class P,which is inherited by both M and N
• Create an object for class p,ie P p
• Call p.get_m(),assign the value in to ‘m’
• Call p.get_n(),assign the value in [...]

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];
int roll,zip;
public: stu ( );//Constructor
~stu( );//Destructor
void read( );
void disp( );
};
stu :: [...]

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
PROGRAM:

#include<iostream.h>
#include<conio.h>
class equation
{
private:float a,b,c;
public: void getinfo(float a, float b,float c );
void display( [...]

Lexical analyzer converts stream of input characters into a stream of tokens. The different tokens that our lexical analyzer identifies are as follows:
KEYWORDS: int, char, float, double, if, for, while, else, switch, struct, printf, scanf, case, break, return, typedef, void
IDENTIFIERS: main, fopen, getch etc
NUMBERS: positive and negative integers, positive and negative floating point numbers.
OPERATORS: +, [...]
