How do you find simple interest using constructor in c plus plus?

Answer 1

#include<iostream.h>

#include<conio.h>

Class interest

{

Private:

Float principle, time, rate, interest;

Public:

Interest ();

Interest (float, float, float);

Void display ();

};

Interest:: interest ()

{

Interest =0;

Principle = 0;

Time=0;

Rate=0;

}

Interest:: Interests (float p, float t, float r)

{

Principle=p;

Time=t;

Rate=r;

Interest=0;

}

Void interest:: display ()

{

Interest = (principle * time * rate) /100;

Cout<<"\n interest="<<interest;

}

Void main ()

{

Float p, t, r;

Cout<<"\n enter the principle, time, rate";

Cin>>p>>t>>r;

Interest obj (p, t, r);

Obj.dispay ();

getch ();

}
