Re: C++ coding problem..

Create a Class Employee. This class holds member variables: employee number and salary. It has an array of 4 employees and includes 4 employee number and salary.
Has 2 member functions:
Get() employee detail, namely number and salary
Display() employee detail
Create main()

I'm really not sure how to do the arrays and please correct my mistakes..
--------------------------------------------------------------------

C++ Syntax (Toggle Plain Text)
class Employee
{
private:
int eNumber;
double eSalary;
public:
Employee()
{
eNumber = 1;
eSalary = 1000;
}
 
double getESalary();
void displayInfo();
};
 
int Employee::getENumber()
{ return eNumber;
}
double Employee::getESalary()
{ return eSalary;
}
void Employee::displayInfo()
{ cout << endl << "Number : " << eNumber;
cout << endl << "Salary : " << eSalary;
} int getENumber();
class Employee
{
private:
int eNumber;
double eSalary;
public:
Employee()
{
eNumber = 1;
eSalary = 1000;
}

double getESalary();
void displayInfo();
};

int Employee::getENumber()
{ return eNumber;
}
double Employee::getESalary()
{ return eSalary;
}
void Employee::displayInfo()
{ cout << endl << "Number : " << eNumber;
cout << endl << "Salary : " << eSalary;
} int getENumber();

How is the array is supposed to be inserted into the function? Can show me please, I am really at loss...
Let's say 4 employee number and salary, (a1, 100; b2, 200; c3, 300; d4, 400)

Re: C++ coding problem..

then you need something like this.you need to do this after the withdrawal has been made and not before

C++ Syntax (Toggle Plain Text)
    double interest=0;
    interest=(0.05)*deposit; //or
    interest=((5/100))*deposit;
    deposit=interest+deposit; //this will add   the interest amount to the current balance
    double interest=0;
    interest=(0.05)*deposit; //or
    interest=((5/100))*deposit;
    deposit=interest+deposit; //this will add   the interest amount to the current balance

Re: C++ coding problem..

Class Account
Hold variables of interest rate and deposit.
Make deposit() Withdrawal() function that checks if money in the account is enough to be withdrawn.
Show output if deposit $5000 for 12 months. 5% interest rate.
Initial deposit $20000
Write main ()
----------------------------------------------------------------
I'm not sure how to do the function to count for interest rate.
----------------------------------------------------------------

C++ Syntax (Toggle Plain Text)
#include <string>
#include <stdio>
#include <stdlib>
#include <conio>
#include <iostream>
 
class Account
{
private:
int Interest;
double Deposit;
public:
Account()
{
Interest = 0.05;
Deposit = 20000;
}
 
void makeDeposit();
void withdrawal();
};
 
void Account::makeDeposit()
{ double amount;
cout << endl << "Deposit Amount : ";
cin >> amount;
Deposit = Deposit + amount;
cout << endl << "Balance : " << Deposit;
}
void Account::withdrawal()
{ double amount;
cout << endl << "Withdrawal Amount : ";
cin >> amount;
if((Deposit>=0)&&(Deposit >= amount))
{Deposit = Deposit - amount;}
cout << endl << "Balance : " << Deposit;
}
 
void main()
{
Account theAccount;
theAccount.makeDeposit();
theAccount.withdrawal();
}
#include <string>
#include <stdio>
#include <stdlib>
#include <conio>
#include <iostream>

class Account
{
private:
int Interest;
double Deposit;
public:
Account()
{
Interest = 0.05;
Deposit = 20000;
}

void makeDeposit();
void withdrawal();
};

void Account::makeDeposit()
{ double amount;
cout << endl << "Deposit Amount : ";
cin >> amount;
Deposit = Deposit + amount;
cout << endl << "Balance : " << Deposit;
}
void Account::withdrawal()
{ double amount;
cout << endl << "Withdrawal Amount : ";
cin >> amount;
if((Deposit>=0)&&(Deposit >= amount))
{Deposit = Deposit - amount;}
cout << endl << "Balance : " << Deposit;
}

void main()
{
Account theAccount;
theAccount.makeDeposit();
theAccount.withdrawal();
}

So should I create another function after withdrawal to insert this function or how?

C++ Syntax (Toggle Plain Text)
double interest=0;
    interest=(0.05)*deposit; //or
    interest=((5/100))*deposit;
    deposit=interest+deposit; //this will add   the interest amount to the current balance
double interest=0;
    interest=(0.05)*deposit; //or
    interest=((5/100))*deposit;
    deposit=interest+deposit; //this will add   the interest amount to the current balance

Re: C++ coding problem..

>>I'm really not sure how to do the arrays and please correct my mistakes..

Looks like you need a 2D array. do something like this

C++ Syntax (Toggle Plain Text)
	int array[row][col];
            int i,j;
 
	for(i=0;i<row;i++)
	{
		cout<<"Enter the employee number and salary: "; //will prompt the user for employee number and salary 
 
		for(j=0;j<col;j++)
 
		{
 
			cin>>array[i][j];
 
		}
	}
	int array[row][col];
            int i,j;

	for(i=0;i<row;i++)
	{
		cout<<"Enter the employee number and salary: "; //will prompt the user for employee number and salary 

		for(j=0;j<col;j++)

		{
			
			cin>>array[i][j];

		}
	}

Re: C++ coding problem..

Thanks a lot for your guidance so far... I appreciate it a lot..

but it will only contain an array of 4 and only 4... how to go about that?

Re: C++ coding problem..

I used 4 since you implied that only 4 data will be needed..anyway you can declare a constant size for the array that can be changed. you can put this in your program. but remember it should be a global variable

C++ Syntax (Toggle Plain Text)
const int max=4;
const int max=4;

put the varible max wherever there is number 4. If you feel it is small then you change max to another number.

However, if you want your data to keep growing then you would need a linked list but this is not required in your question..Hope this is helping and let me know if it isnt
