Objects as Function Arguments:

In C program there are several methods to define arguments, and in some case even a

structure can be approved as an argument.  Similarly in C++ in place of structure an object can be defined as an argument.

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 "<

}

void 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;

}

void interest::suminterest(interest i1, interest i2)

{i=i1.i+i2.i;

a=i1.a+i2.a;      }

int main()

{clrscr();

interest i1,i2,i3; // Created three objects

i1.getdata(  1000,10,2); //Calculates interest and amount for object i1.

i1.putdata();

i2.getdata(10000,8,3); //Calculates interest and amount for object i2.

i2.putdata();

i3.suminterest(i1,i2); ////Total interest and amount from object i1 and i2.

i3.putdata();

return 0;
