Hi all, I have a complicated question to ask you and I'm stuck on this.
What I'm trying to do in this project is to ask the user what kind of ingredients they want from this certain store that are in stock. After telling me the ingredient, I will then ask what sizes they want and keep each ingredients in their cart. In the end, I will have to total the whole thing together and list all the ingredients they have chosen and total price in the end.

Here's my first problem in this picture:

I can respond back to the user just fine with the milk part, but when I ask what size sugar they want and they say 8, the last line in this console window pops up too after they say 8. How can I remove this last line about the 10 oz?

Second problem in this picture:
https://40.media.tumblr.com/8cbf4da37672dd58398a162bc2328e0d/tumblr_nvscmtkkOD1qdp21xo1_1280.png

When the user puts in 1, I can respond back by asking what size milk they want. However, if they were to pick something else like let's say...3 or 4, then nothing will pop up in the console window. How can I fix this?

Sorry about the confusion, but I have been stuck on this for awhile now. Thanks in advance.

Your problem is assignment instead of comparison (lines 221/228):
1
2
3
4
5
6
7
8
9
10
11
12
13
14
 
	cin >> ingredient66;
	 if (ingredient66 = 8) // Note: assigns 8
	{
		cout << "\n";
		cout << "8 eggs? I will put it in the cart for you.What else do you like to order?";
		cout << "\n";
	}

	 if (ingredient66 = 12) // Note: assigns 12
	{
		cout << "\n";
		cout << "12 eggs? I will put it in the cart for you. What else do you like to order?";
		cout << "\n";
	}

As @coder777 pointed out, you're confusing yourself over the equality operator and the assignment operator. There's a few other places you have this error as well, namely lines 137, 176, 183, 198, and 204. Also you notice how you have so many repeated messages? I would recommend making a const string variable for that, like
const string confirmMessage = "I will put it in the cart for you. What else would you like to order?".

Also try tagging on endl instead of repeatedly using cout << "\n". In your ingredients menu alone it would cut down the length of the code by half.

Ohhh I see! That fixed the first problem I had. Thank you. Does anyone know how to fix the second problem?
YFGHNG (319)
It has to do with how you wrote your cin statements. Let's take the first one for your milk. What if I entered a number other than 1? The compiler has no way of differentiating that the number I entered in, say 3, was supposed to be for salt. All it knows is that it's supposed to take input for milk. And then it's supposed to take input for milk size.

In other words, you want to have some sort of if else or switch statement dictating which item(s) should go in the shopping cart.
coder777 (8444)
The second problem is (like YFGHNG already stated) that on line 99 you have only one if (ingredient1 == 1) for milk. All other are missing.
