Which container is good for below scenario mentioned.

[Ayush Gupta]

I have scenario where I need to store some data where I can have

count as unique number
and each count should be associated with some data and its value

I was thinking to use map<int, map<string,string>> but since only one data and value will be associated with count will it be overkill to use map<string,string> ?

Kindly suggest

[VRonin]

map<int, tuple<string, string/*, string, ... */> >

Where

• map can be a std::map, std::unordered_map, QMap, QHash or any key-value container and
• tuple is std::pair, QPair or std::tuple or even just a custom struct

@Ayush-Gupta
Do you want to use std:: containers or Qt containers?

[Ayush Gupta]

Qt containers would be good for me

@Ayush-Gupta
Then you will want either QMap or QHash, as discussed in https://doc.qt.io/qt-5/qmap.html#details according to your requirements.
