Question

create a class in C++ having 

the following 4 private members:

one double variable representing the balance of a bank account

on string variable representing the bank account number

a function to deposit money from the bank account

a function to withdraw money from the bank account

the following 2 public members:

-two wrapper functions.

- one parameterless constructor

- one constructor initializing the account balance and account number

- sample:

#include <iostream>
using namespace std;

class account
{
    public:
    account();
    account(string s, double m);
    
    void setMoney(double b);
    void getMoney(double b);
    
    private:
    double money;
    string accountNo;
    
    void withdraw(double b);
    void deposit(double b);
    
};

    account::account()
    {
       money=0;
       accountNo="12345";
    }
    account::account(string s, double m)
    {
       money=m;
       accountNo=s;       
    }
    
    void  account::withdraw(double b)
    {
        if(money<b)
        {
           cout<<"not enough"<<endl;
        }
        else
        {
            money = money-b;
        }
        cout<<"withdraw your new balance is "<<money<<endl;
    }
    void account::setMoney(double b)
    {
        deposit(b);
    }
    void  account::getMoney(double b)
    {
        withdraw(b); 
    }
    
    void  account::deposit(double b)
    {
        money = money+b;
        cout<<"deposit: your new balance is "<<money<<endl; 
    }

int main() 
{
   account a;
   
    a.setMoney(1000);
    a.getMoney(500);
    
   account b("23456", 1234);
    b.setMoney(2000);
    b.getMoney(600);
   
   return 0;
}

Answer 1

#include <iostream>
using namespace std;

class account
{
public:
account();
account(string s, double m);
  
void setMoney(double b);
void getMoney(double b);
  
private:
double money;
string accountNo;
  
void withdraw(double b);
void deposit(double b);
  
};

account::account()
{
money=0;
accountNo="12345";
}
account::account(string s, double m)
{
money=m;
accountNo=s;   
}
  
void account::withdraw(double b)
{
if(money<b)
{
cout<<"not enough"<<endl;
}
else
{
money = money-b;
}
cout<<"withdraw your new balance is "<<money<<endl;
}
void account::setMoney(double b)
{
deposit(b);
}
void account::getMoney(double b)
{
withdraw(b);
}
  
void account::deposit(double b)
{
money = money+b;
cout<<"deposit: your new balance is "<<money<<endl;
}

int main()
{
account a;

a.setMoney(1000);
a.getMoney(500);
  
account b("23456", 1234);
b.setMoney(2000);
b.getMoney(600);

return 0;
}

Expected output:
