## Code for Program that calculates area of triangle and rectangle using inheritance in C++ Programming

```

#include <iostream.h>
#include <conio.h>

class shape
{
protected:
double x,y;
public:
virtualvoid get_data()=0;
virtualvoid display_area()=0;
};

class triangle : public shape
{
public:
void get_data(void)
{
cout<<"\n\n=====Data Entry for Triangle=====\n\n";
cout<<"Enter base and height respectively : ";
cin>>x>>y;
}
void display_area(void)
{
cout<<"\n\n=====Area of Triangle=====\n\n";
double aot;
aot = 0.5 * x * y;
cout<<"Area of Triangle is "<<aot;
}
};

class rectangle : public shape
{
public:
void get_data(void)
{
cout<<"\n\n=====Data Entry for Rectangle=====\n\n";
cout<<"Enter length of two sides  : ";
cin>>x>>y;
}
void display_area(void)
{
cout<<"\n\n=====Area of rectangle=====\n\n";
double aor;
aor = x * y;
cout<<"Area of Rectangle is "<<aor;
}
};

void main()
{
clrscr();
triangle tri;
rectangle rect;
shape *list[2];
list[0]=&tri;
list[1]=&rect;

int choice;
while(1)
{
clrscr();
cout<<"\n=====MEASURES OF DIFFERENT SHAPE=====\n";
cout<<"1) Area of Triangle\n";
cout<<"2) Area of Rectangle\n";
cout<<"3) Exit\n";
cin>>choice;
switch(choice)
{
case 1 : list[0]->get_data();
list[0]->display_area();
getch();
break;
case 2 : list[1]->get_data();
list[1]->display_area();
getch();
break;
case 3 : goto end;
default: cout<<"\n\nInvalid choice\nTry again\n";
