/*
By using this->name = name;, you are explicitly telling the compiler:
"Take the local parameter name and assign it to the name variable belonging to this specific object."
*/
/*
The this pointer is an implicit, hidden pointer passed automatically to every non-static member function and constructor in C++. 
It holds the exact memory address of the object that currently called the function.
