Conversion Operator Problem

Hello all expert C++ programmer, i truly new to C++ programming.

I have a exercise where need to calculate the monthly interest with the balance supplied.

Header File:

Code:

#pragma once

class savingAccount
{
	static double annualInterestRate;
	double balance;
	double monthlyInterest;
public:
	savingAccount() : balance(0), monthlyInterest(0){}
	explicit savingAccount(double balance, double monthlyInterest) 
		:balance(balance), monthlyInterest(monthlyInterest){}
	
	void calMonthlyInterest();
    static void modifyInterestRate();

	~savingAccount(){}
};


/* Static data member cannot initialized
   by constructor
*/

Implementation File:

Code:

#include<iostream>
#include<cstdlib>
#include "Saving Account.h"

using std::cout;
using namespace std;

double savingAccount::annualInterestRate = 0.05;

int main(int argc, char *argv[])
{
	savingAccount peter(2000);
	savingAccount nicholas_tse(3000);
    
	peter.calMonthlyInterest();

	return EXIT_SUCCESS;
}
// -----------------------------------------
void savingAccount::calMonthlyInterest()
{
	monthlyInterest = (balance * annualInterestRate)/12;
}
// -----------------------------------------

I hope someone cna help me out.

Thanks for your help.

Your help is greatly appreciated by me and others.

 

I have set the one of the constructor explicit where to enhance one argument is been supplied.

 

What is the reason of having explicit constructor?
Where is the defintion of constructor corresponding to

Code:

savingAccount peter(2000);

 

No definition for Single argument constructor in ur program

If u want a simple solution means
add the following line to ur header file

savingAccount(double balance):balance(balance){}


so that u got an answer...........
