Vending Machine Update

Now I have added two new functions to this code. I've added an "Invalid Answer" text to make sure that the player doesn't answer anything more than what's provided on screen, and I've added an "Insufficient Funds" text to let the player know that they've run out of money.

int main()
{
	int PlayerWallet = 20;
	
	int PlayerAnswer;

	int DrinkPrice = 0;

	do {
	
		cout << "Welcome to TC Vending!! \n\n";

		cout << "Please make a selection down below!! \n\n"; 

		cout << "1). Sprite - $3 \n\n 2). Coke Zero - $3 \n\n 3). Water - $3 \n\n 4). Fanta - $5 \n\n 5). Pepsi - $5 \n\n 6). Cancel Selection \n\n"; //Displays the list of drinks that are available to buy

		cin >> PlayerAnswer;

	if (PlayerAnswer == 1) //If the player answers 1, then the text will tell them that the player has bought a Sprite
	{
		cout << "Thanks for buying Sprite!!\n\n";
		PlayerWallet = PlayerWallet - 3; //The player wallet will subtract whatever the cost of the drink is
		cout << "Your current amount is\n\n" << PlayerWallet; //Will display the amount of money the player has left

	}

	else if (PlayerAnswer == 2) //If the player answsers 2, then the player will buy a Coke
	{
		cout << "Thanks for buying Coke Zero!!\n\n";
		PlayerWallet = PlayerWallet - 3;
		cout << "Your current amount is \n\n" << PlayerWallet;
	}

	else if (PlayerAnswer == 3) //If the player answers 3, then the player will buy a water
	{
		cout << "Thanks for buying Water!!\n\n";
		PlayerWallet = PlayerWallet - 3;
		cout << "Your current amount is \n\n" << PlayerWallet;
	}

	else if (PlayerAnswer == 4) //If the player answers 4, the player will buy a Fanta
	{
		cout << "Thanks for buying Fanta!! \n\n";
		PlayerWallet = PlayerWallet - 5;
		cout << "Your current amount is \n\n" << PlayerWallet;
	}

	else if (PlayerAnswer == 5) //If the player answers 5, the player will buy a Pepsi
	{
		cout << "Thanks for buying Pepsi!! \n\n";
		PlayerWallet = PlayerWallet - 5;
		cout << "Your current amount is \n\n" << PlayerWallet;
	}
	else if (PlayerAnswer == 6)
	{
		cout << "Exiting Program!! \n\n";
	}
	
	else
	{
		cout << "Invalid Answer \n\n";
		system("pause");
		system("cls"); //Clears the screen
	}
		
	if (PlayerWallet <= 0 || PlayerWallet < DrinkPrice) 
	{
		cout << "Insufficient Funds \n\n\n"; //Will display if the player runs out of money
		PlayerWallet = PlayerWallet - DrinkPrice;
		system("pause");
		system("cls");

	}

	} while (PlayerAnswer > 6 || PlayerAnswer < 6);
	

	system("pause");
}
