A program is implemented to find the area of a circle and area of a r

1.	A program is implemented to find the area of a circle and area of a rectangle with two functions having same name but with different signature.(a) Name the concept (b) Explain this concept by writing the above program.
Answer» (a) Polymorphism (b) #include<iostream> #include<cmath> using namespace std; float area(float r) { return(3.14pow(r,2)); } int area(int I, int b) { return(Ib); } void main () { float r,Ac; int I,b,Ar; cout <<"Enter the radius of the circle"; cin>>r; AC = area(r); cout <<"Enter the length and breadth"; cin>>I>>b; Ar = area(I,b); cout<<"Area of circle is"<<Ac; cout<<"\n area of rectangle is"<<Ar; } Here the function names are same but the return type and number of parameters are different hence distinguish the functions.

A program is implemented to find the area of a circle and area of a rectangle with two functions having same name but with different signature.(a) Name the concept (b) Explain this concept by writing the above program.

Answer»

(a) Polymorphism

(b) #include<iostream>

#include<cmath>

using namespace std;

float area(float r)

{

return(3.14*pow(r,2));

}

int area(int I, int b)

{

return(I*b);

}
void main ()

{

float r,Ac;

int I,b,Ar;

cout <<"Enter the radius of the circle";

cin>>r;

AC = area(r);

cout <<"Enter the length and breadth";

cin>>I>>b;

Ar = area(I,b);

cout<<"Area of circle is"<<Ac;

cout<<"\n area of rectangle is"<<Ar;

}

Here the function names are same but the return type and number of parameters are different hence distinguish the functions.
