How a class function can be used as comparator

Please see this https://www.geeksforgeeks.org/multiset-key_comp-function-in-c-stl/
We’re overlaoding key_comparator() function in mutliset by sending custom comparator

If your doubt is resolved please close it

But in sort function we were only using function comparator but in this case operator overloading is done how to identify what to di when!??

@shampblocks
Custom comparator is called each time you insert or delete an element in multiset. while adding the new element compare is called by multiset class to determine where to place the element in mutliset.

So whenever I am using conparator if it’s conparator of class then I should do overloading??

@shampblocks
If you need to change the default comparator to your own logic of comparison then you need to use it. If your doubt is resolved please close it.
