R,L-value move forward.txt

The main difference between "std::move" and "std::forward" is the type of reference they return.

"std::move" is function themplate that is used to convert and lvalue into an rvalue. It is tipically used to explicitly move
resources from one object to another, rather than copying them. When called on an lvalue, std::move returns and rvalue
reference to the original object, indicating that the objects resources can be moved or consumed.

On the other hand, "std::forward" is a function template that is used to forward an argument to another function or 
constructor, preserving its original lvalue or rvalue status. It is tiypically used in conjunction with template function 
overloading and perfect forwarding. When called on an lvalue, "std::forward" returns a reference to the original object, so
that the called function or constructor can acess the original object. When called on an rvalue, std::forward returns an rvalue reference to the original
object, so that the called function or consturctor can move or consume the original object.

In summary, "std::move" is used to explicitly move resources from an object and it returns an rvalue reference, while 
"std::forward" is used to perserve the original value category of an argument and it returns either lvalue or rvalue 
reference depending on the original value category of the argument.
