Few doubts regarding this video

#1

First is while overloading the operator why we have to make the function const ? and can you please explain me how we made our own hash funtion ?

Hello @sukritbansal01

we make any function constant when we dont want them to make any changes on the objects/data they are dealing with.

here hash function and then other != is dealing with objects and becuase we dont want these functions to make any changes on object we make them const

the operator that we overload () will take student object and then calculate sum of length of first and last name .and then use it as key/hash value.
