Function Returning Object:

This program is like to the previous program except the function returns object.  The

main rule to be remembered is the function returning object must be defined as friend function in the class.

class interest

{float i,p,n,r,a;

public:

void getdata(int gp, int gn, int gr);

void putdata(void)

{cout<<"Interest is "<

cout<<"Amount is "<

}

Friend interest suminterest(interest,interest);

};

void interest::getdata(int gp,int gn, int gr)

{p=gp;n=gn;r=gr;

cout<<"Enter Principal: "<<"\n";

cin>>p;

cout<<"Enter Year: "<<"\n";

cin>>n;

cout<<"Enter Rate: "<<"\n";

cin>>r; i=(p*n*r)/100; a=p+i;

}

interest suminterest(interest i1, interest i2)

{interest i3; i3.i=i1.i+i2.i; i3.a=i1.a+i2.a; return i3;

}

int main()

{clrscr();

interest i1,i2,i3; i1.getdata(  1000,10,2); i1.putdata(); i2.getdata(10000,8,3); i2.putdata();

i3 = suminterest(i1,i2);

i3.putdata();

return 0;

}
