Question

I am looking for something like a school time table. Based on two input – Day of the week and Time of the day, one decides the subject. To implement this in c++, I was thinking of something like “map < pair < int, int>, int>”.
I was reading here to use a key class and operator overloading.
Is there any other elegant way of doing it?

Thanks in Advance

Answer 1

That’s not a map with two keys (which would allow you to look up items from knowledge of just one key), it’s a composite key, and map<pair<day, time>, subject> should work just fine.

Also consider map<day, map<time, subject>>.
