help please

[ashleyoliver11]

I cannot get the item's names to show up on the same line, and I'm not sure what I'm doing wrong. Can someone please look at my code and help me get through this part of my assignment? Also, there are some parts on the code that I haven't defined yet but that's because I'm still working on them, and they're commented out right now since I'm trying to figure out how to put the item names on the same line and can't get past it. Thanks to anyone who helps me.

What is the assignment description?

Don't use endl if you want the next output to be on the same line.

Homework 3 – PROG 1003 Shopping Cart 3
Building on the program from Homework 2 - Cart.cpp.
Following the examples, we wrote in class, read an unknown number of items from the provided text file – ItemList.txt. You will use the same data types - Item name should be a string, item type should be a char, and item price should be a double.
 All output to the user (on the console) should show a “$” and be rounded to two decimal places with a pleasing format – set column widths and spacing.
 Assume a tax rate of 9% for standard items with a category of ‘N’
 Assume a tax rate of 12.5% for special items with a category of ‘X’
 Assume a tax rate of 0% for food items with a category of ‘F’
 Calculate a subtotal, tax, and total.
 Display the total to the user.
 Allow the user to enter the amount to pay (do not assume the amount will be equal to or more than
what is due, or that the input will be a valid number). Display the change due to the user.
 Create a print friendly receipt that closely matches the one provided – Receipt.txt
The point of this exercise is to learn how to use loops to handle an unknown amount of information and how to manipulation file I/O as the same time. Remember no magic numbers, follow the coding conventions, that all output should be properly formatted.


Here is the assignment description.

There's about 100 of them, I can get the single words to show up just fine but the ones like "street lights" and "rubber band" I cannot get to show up on the same line. I think it has something to do with my ignore command but I'm not quite sure how to get it to show up properly on the same line, I've tried moving the ignore command and taking things out but nothing seems to get it to work.

The problem is not the ignore() function call, the problem is that the extraction operator stops processing the string when it encounters a whitespace character. If you want to retrieve a string that contains spaces you should be using getline(), not the extraction operator. Looking at your input file I suggest you use getline() to read every line then use a stringstream to parse the line to convert the string to the double and the character.
