Ballpark challenge in C++

Question

I’m new to coding in general. My previous experience is only VBA, which does share some similarities but a lot of differences that I’m feeling very green.

So I’m looking for some help completing this challenge in C++. I have tried a few different attempts but I’m just not getting it. I know once someone points me in the right direction, I’ll be like “duh”
I know I could just write it all out in the simplest terms but I don’t want to do that. It isn’t best practice.

Thanks in advance

Answer 1

HonFu I really hate it when people start answering like this. Not even one single comma or point, just plain text and random sentences one after another, instead of one single complete answer. I really wish I could be a mod to just ban them of give them warnings, so they can understand how serious it should be.

1. If you want to read in a string containing whitespaces, std::cin won't get you anywhere. It is designed so that any sort of whitespace character acts as a delimiter. You will want to use std::getline() instead:

https://en.cppreference.com/w/cpp/string/basic_string/getline

2. If you don't yet know how to split a string, have a look at how others tackled the problem for some inspiration:

3. If you combine the two approaches from above, you will end up with a container like std::vector

https://en.cppreference.com/w/cpp/container/vector

containing the different strings.
All that is left is to go over the container and to compare each string to the possible orders. Depending on the result, add to the total price.

This should be enough to get you started for a second (hopefully successful) approach. If you have any other issues, feel free to ask.

Answer 3

Why don't you share your attempt here so that people can take a look?

Answer 4

YCS VENOM, do you actually think before you post something?

I was asking the poster of this question to share their attempt.

This should be obvious.

Answer 5

YCS VENOM, your posts start to look like spam.

Aymane Boukrouh, it's not even a split-up answer yet - so far it's only babble.

Answer 13

Well... Thanks everyone for coming to my aid. I no longer have any code, unfortuantely. if the code I use completely fails, which it did, I would scrap and start again.

I honestly don’t know where to begin. I dont know how to split the string; how to allow the cin function to read spaces; how to assign values to the input values etc
my knowledge is a bit incomplete im afraid when it comes to these type of challenges. If I could even be pointed in the right direction I could have another try on my own.

Thanks for all your help.

Answer 14

Hi there, i tried going over the code and information you provided and still couldnt even get the first part working, nevermind continuing onto assigning values to the strings and totaling them up. Any further help you can provide would be great.

On a side note, this challenge is cobsidered easy. this all seems complicated for an easy challenge. I wonder if this is easier on phython.

Answer 18

thank you for all your help with this. I believe in trying to complete this and getting your help, I lack the knowledge at this time to properly solve this challenge. However, I won’t abandon it. I will simply learn more and eventually, when I know enough, I will be able to solve it. If I attempted it again I might have gotten the answer but I wouldn’t understand it fully.
Thank you for all your help.
