►Lesson Description: In this lesson I give you a tour of the std::map. std::map is an associative and ordered container for storing keys and values. In general you will get logarithmic performance using this data structure for insertion, removal, and updates. I'll show you how to iterate through the map several different ways, some tips on 'using' for creating your maps, and how to create a custom comparator if you use a custom key.

Man, you are criminally underrated. Wishing you a lot of success.

I'm going through the STL series rn and I just wanted to say thanks, these videos are super helpful!!

Mike, I really appreciate seeing the non-trivial uses. Few online examples cover anything more than just a rehash of what the basic definition states. And it is always good to see the places where your code doesn't compile on the first pass: really helpful to those of us learning the quirks of the language😅. While it may add a few seconds to the video, it adds miles to troubleshooting.

@16:50 is it Ok to use negative numbers for types that is unsigned long int?

Excellent video again! Would love to see a series on streams, especially with binary data!

Thanks Mike for these great STL series. I am learning a lot. I just have a question: if i have a vector of size n and want to create a std::map from this vector, would that be o(log(n))*n?!

Quintessential Prof, Thanks a lot.
From the above, is Set, Map without value?

Hello Mike! Nice vibe on your videos, thank you! Btw, I tried understanding why the member operator< didn't work for you, but couldn't come up with any explanation. I had no problems with both a member operator< and a friend one 🤔.

how this working : mymap["edge1"] = Edge(0, 0 ) ; // for me this is giving error, means there should be constructor ? need your help ...

Would you please make a video on structured bindings? thank you. 😍
