Question

*using c++*

Construct a class named Savings containing three floating-point data members named balance, rate, and interest and a constructor that initializes each data member to 0. This class should be established with typical two files(.h and .cpp). Include a member function that inputs a balance and rate and then calculates an interest. The rate should be stored as a   percent, such   as   6.5   for   6.5%,   and   the   interest   is   computed   as   interest   = (balance)(rate/100). Add a member function to display all data member values. Use functions in main(), and display the results.

Answer 1

#ifndef Savings_H_
#define Savings_H_

class Savings {
private:
   float balance;
   float rate;
   float interest;
public:
   Savings();
   void inputBalance();
   float getInterest();
};

#endif

#include "Savings.h"

#include <iostream>

using namespace std;

Savings::Savings() {
   balance = 0;
   rate = 0;
   interest = 0;
}

void Savings::inputBalance() {
   cin >> balance >> rate;
   interest = balance * (rate / 100.0);
}

float Savings::getInterest() {
   return interest;
}

#include <iostream>
#include "Savings.h"

using namespace std;

int main() {
   Savings s;
   s.inputBalance();
   cout << "Interest: " << s.getInterest() << endl;
   return 0;
}
