Thread: What to use: array-vector-list

I have a series of 12 strings of under 25 characters each.
I have 1 two-digit number for each string.
I would like to be able to access each element with an int (index #) and associate the corresponding two-digit number with the string.
As an example:

Code:

std::string FRUITS[] = {"Fruit1", "Fruit2", "Fruit3", "Fruit4"}; // -through 12...
int QTY[] = {02,09,12,24}; // -one per string
//...so I have 12 of Fruit3 in the example.

I also want to be able to access this 'storage' with a function, which will also access other 'storage' with the same design, but possibly a different number of entries. A loop will be run per entry, which is why I need the total (unknown) number of entries.
Basically I stumbled upon this question trying to learn something else, and do not want to spend the next week learning something, only to find out there is a better way to approach what I am doing.
I guess I would just like to be pointed in the most beneficial direction,
arrays
multidimensional array
vector
list
other?
Also, for curiosity, how would this answer differ if I needed the ability to add elements on the fly? (perhaps a project to play with after this)

It sounds like you want a std::vector<std::pair<std::string, int> >, or maybe to define a Fruit class so you can have a std::vector<Fruit>. Or maybe you do not actually need a sequence to be accessed by index, and thus a std::map<std::string, int> is appropriate.

It may be easier if you would tell us what you are trying to model instead of speaking cryptically though generally.

Thank you, it seems like class is what I will need. Basically I am trying to learn C++ without school (yet). I do not actually have a set of instructions to follow, or a desired result. Though sometimes when people post their homework instructions I copy those down and try to write it.
I have had a hard time coming up with something to aim for so this is just a little program to manipulate data. So far it is (in my mind) at stage 0, having a need for a program.
lol...
So what I come up with is an inventory type program, like for a supermarket. (I have done more thinking about what i 'need') I guess I want to aim for something to accept inventory input, and display output about the inventory. I am learning classes at this point and that sounded like a good topic to organize... food
I have 0 code yet, just coming up with ideas of what to do that can include things to learn.
I will look into map like you suggested, it looks very useful.
TY again and I am sure I will need another push at some point along the way.
