hash in C++ | std::hash in C++

In this video we will learn what is std::hash in c++11.
std::hash is a template class defined in the C++ Standard Library header "functional". It is used to generate hash values for objects of various types. Hashing is a process of mapping data of arbitrary size to a fixed-size value, typically for use in data structures such as hash tables or hash-based data structures like std::unordered_map, std::unordered_set, etc.
std::hash provides a default hash function for built-in types and allows users to specialize it for their custom types.

The video thumbnail colors works great, you should keep that style.

Thanks for the comment dude..

It may be very unlikely, but is it possible to have two completely different objects with the same hash value? Is it safe to use a hash as an identifier?

[@CppNuts]

If hash value is same for two objects then we can have a linkedlist data structure to maintain those object in the same list.

[@deepikapatait6861]

if you provide this in hindi it would be more helpfull and also become easy to understand for all of us.

[@CppNuts]

Sure!!
