Account Savings using classes

[Deadweight77]

I'm having trouble onto how I can deposit and withdraw money correctly and show the total money in bank account 1.

#include <iostream>
using namespace std;

class SavingsAccount
{
public:
	//SavingsAccount();
	//SavingsAccount(int dollars, int cents);
	void deposit(int dollars, int cents);
	void withdraw(int dollars, int cents);
	void total(int dollars, int cents);
	void set(int dollars, int cents);
	void convert(int dollars, int cents);
private:
	double D_balance;
	double W_balance;
	double total_money;
};

int main()
{
	SavingsAccount bank1, bank2;
	int dollars, cents;
	bank1.set(30, 65);//setting bank1 to have initial money as I call upon the void set function above
	int anwser;
	cout << "Would you like to 1.Deposit or 2.Withdraw?";
	cin >> anwser;
	if (anwser == 1)
	{
		cout << "Enter in how much you want to deposit in dollars:";
		cin >> dollars;
		cout << "Enter in how much you want to deposit in cent:";
		cin >> cents;
		if (dollars < 0 || cents < 0)
		{
			cerr << "Invalid!" << endl;
			exit(1);
		}
		bank1.deposit(dollars, cents);//should call upon the seprate deposit funtction below
	}
	else if (anwser == 2)
	{
		cout << "Enter in how much you want to withdraw in dollars:";
		cin >> dollars;
		cout << "Enter in how much you want to withdraw in cents:";
		cin >> cents;
		if (dollars < 0 || cents < 0)
		{
			cerr << "Invalid!" << endl;
			exit(1);
		}
		bank1.withdraw(dollars, cents);
	}
	else
	{
		cerr << "Error! Input not valid!" << endl;
		exit(1);
	}
}
void SavingsAccount::set(int dollars, int cents)
{
}

void SavingsAccount::convert(int dollars, int cents)
{
	dollars = cents / 100;
	cents = dollars - cents;
}

void SavingsAccount::deposit(int dollars, int cents)
{
	D_balance = dollars + cents * .01;
	
}

void SavingsAccount::withdraw(int dollars, int cents)
{
	W_balance = dollars + cents * .01;
}

void SavingsAccount::total(int dollars, int cents)
{
	total_money = D_balance - W_balance;

}

a basic idea

void account::deposit(double amount){
   this->total_money += amount;
}
void account::withdraw(double amount){
   if(this->total_money >= amount)
      this->total_money -= amount;
}
double account::total() const{
   return this->total_money;
}
