PROGRAM 1

WRITE A PROGRAM TO IMPLEMENT

FUNCTION OVERLOADING

#include#include

float add(int,float);float add(float,int);

void main(){clrscr();cout

PROGRAM -2

WRITE A PROGRAM TO SHOW THESEQUENCE OF INVOKING CONSTRUCTORIN DERIVED CLASS

#include#include

Class a{Public:a(){

Cout


5/21

Public:d()

{

Cout


6/21

PROGRAM-3

WRITE A PROGRAM TO CALCULATE AVERAGE OFTHREE NUMBERS USING CLASS

#include#include

class avg{int a,b,c;float d;public:

void getdata(void){cout


7/21

OUTPUT: ENTER THE VALUE OF A: 4

ENTER THE VALUE OF B: 6ENTER THE VALUE OF C: 2THE AVERAGE OF GIVEN VALUES IS: 3

PROGRAM-4

WRITE A PROGRAM TO IMPLEMENT STATICMEMBER FUNCTION

#include#includeclass test{int code;static int count;public:void setcode(void){code=++count;}static void showcount()

{cout


9/21

OUTPUT:

count=2count=3

code is=3code is=1code is=2

WRITE A PROGRAM TO IMPLEMENTOPERATOR OVERLOADING

#include#includeClass cpmplex{int x,y;

public:void getvalue(){coutx;couty;}void display()

{cout


11/21

c3=c2+c1;c3.display();getch();}

OUTPUT:

Enter the values of x:4Enter the values of y:5

Enter the values of x:2Enter the values of y:5

For 1st object

The value of x is:4The value of y is:5

For 2nd objectThe value of x is :2The value of y is:3

For 3rd object (after addition)The value of x is:6The value of y is:8

PROGRAM-9

USING THREE CLASSES,DESIGN A PROGRAM THATWILL ACCEPT DIMENSION OF A TRIANGLE ORRECTANGLE AND DISPLAY THE AREA.REMEMBER THETWO VALUES GIVEN AS INPUT WILL BE TREATED ASTHE LENGTH OF TWO SIDE IN THE CASE OF TWORECTANGLE AND AS BASE AND HEIGHT IN THE CASEOF TRIANGLES AND USED AS FOLLOW:AREA OF RECTANGLE =X*YAREA OF TRIANGLE = *X*Y

OUTPUT:

Enter the value of x:4Enter the value of y:6

Area of triangle is:12

Area of rectangle is:24

PROGRAM-10

A PHONE NO,SUCH AS(212) 767-8900,CAN BETHOUGHT OF AS HAVING THREE PARTS:THE AREACODE(212), TO EXCH(767) AND THE NO(8900). WAPTHAT USES A STRUCT TO STORE THES THREE PARTSOF A PHONE NO SEPARATELY. CALL THE STRUCTPHONE. CREATE TWO STRUCT VARIABLE OF TYPEPHONE. INITIALIZE ONE, AND HAVE THE USER INPUT A

NUMBER FOR THE OTHER ONE.THEN DISPLAY BOTHNUMBERS. THE INTERCHANGE MIGHT LOOK LIKE THIS:ENTER YOUR AREA CODE, EXCHANGE,ANDNUMBER:415 555 1212 MY NUMBER IS (212)767-8900YOUR NUMBER IS (415) 555-1212
