1) At the end of your while(productNum != 4), you don't ask user for another input, so it's stuck in an infinite loop (unless you type 4 in the beginning)

2)
1
2
3
4
5
 
cout << "Enter 1 for Tomato..." << productNum1 << endl;
cout << "Enter 2 for Orange..." << productNum1 << endl;
cout << "Enter 3 for Banana..." << productNum1 << endl;
if(productNum1 == 1)
...

as you can see above, you ask user for input, but no input statement appears

1
2
3
 
cout << "$5.00 per lb of Chicken..." << endl;
cout << "How many pounds of Chicken would you like to purchase..." << productQty << endl;
productPrice = productQty * 5;

you missed input statement again
