Can't figure out why user input isn't showing up in program.

[pleaseINeedHelp]

I am having trouble finding out why user input is not showing up in the program after it is entered and the menu comes up. The program asks the user to input a product name then that product name is supposed to be the first option on the menu, however when the menu comes up it is blank. Can anyone tell me what I am doing wrong I am pretty sure it has to do with *newProduct in my code but I could be wrong and can't figure out the problem. Thanks for any help.

void displayProducts()
{
	int total;
	//array for quantity
	int quantity[3];
	int i;
	for (i = 0;i < 3; i++)
		quantity[i] = 0;
	char selection = 'a';
		//trying to dynamically allocate memory for products array while for the first element 
		//in the array having the user input the first item name and dynamically allocating 
		//that element based upon the size of the name the user imputs
	string products[3];
	string *productsPtr = new string[3];
	for (int i=0; i<3;i++)
	{
		productsPtr[i] = products[i];
	}
	string uInpt;
	string temp;
	cout << "enter the first product name" << endl;
	cin >> temp;
	int len = temp.length() + 1;
	string *newProduct = new string[len];
	temp = *newProduct;
	products[0] = *newProduct;
	products[1] = "oranges";
	products[2] = "bananas";
	cout << "you entered " << products[0] << endl;
        cout << "Press 4 to proceed to order summary." << endl << endl;
		cout << "Enter selection: ";
		// read user selection
		do
		{
			cout << "The list of products are below" << endl;
			cout << "product 1:" << products[0] << endl;
			cout << "product 2:" << products[1] << endl;
			cout << "product 3:" << products[2] << endl;
		cin >> selection;
		// program crashes when entering quantity?
		
		switch (selection)
		{
		case '1':
			cout << "You selected - " << products[0] << endl;
			cout << "Please enter quantity. ";
			cin >> quantity[0];
			break;

		case '2':
			cout << "You selected - oranges" << endl;
			cout << "Please enter quantity. ";
			cin >> quantity[1];
			break;

		case '3':
			cout << "You selected - bananas" << endl;
			cout << "Please enter quantity. ";
			cin >> quantity[2];
			break;

		case '4':
			cout << "Thank you." << endl;
			break;

			//if  1, 2, 3 or 4 is not selected then go to the default case
		default: cout << "Invalid selection. Please try again";
			// no break in the default case
		}
		cout << endl << endl;
	}
		while (selection != '4');

		cout << "\nYou ordered " << quantity[0] << products[0] << " for a cost of $" << quantity[0] << endl;
		cout << "You ordered " << quantity[1] << " oranges" << " for a cost of $" << quantity[1] << endl;
		cout << "You ordered " << quantity[2] << " bananas" << " for a cost of $" << quantity[2] << endl;
		//using the quantity array to calculate total
		total = (quantity[0] + quantity[1] + quantity[2]);
		cout << "Your grand total is $" << total << endl;
		cin.get();
