What's the difference between assignment operator and copy ...
the difference between a copy constructor and an assignment constructor is: In case of a copy constructor it createsanewobject. (<classname> <o1>=<o2>) In case of an assignment constructor it will not create any object means it apply on already created objects (<o1>=<o2>).
Copy Constructor vs Assignment Operator in C++ - GeeksforGeeks
But, there are some basic differences between them: Copy constructor. Assignment operator. It is called when a new object is created from an existing object, as a copy of the existing object. This operator is called when an already initialized object is assigned a new value from another existing object.
Copy assignment operator - cppreference.com
A copy assignment operator is a non-template non-static member function with the name operator= that can be called with an argument of the same class type and copies the content of the argument without mutating the argument. Syntax. For the formal copy assignment operator syntax, see function declaration.
c++ - The copy constructor and assignment operator - Stack ...
The assignment operator is used to change an existing instance to have the same values as the rvalue, which means that the instance has to be destroyed and re-initialized if it has internal dynamic memory. Useful link : Copy Constructors, Assignment Operators, and More; Copy constructor and = operator overload in C++: is a common function possible?
Copy constructors and copy assignment operators (C++)
Use an assignment operatoroperator= that returns a reference to the class type and takes one parameter that's passed by const reference—for example ClassName& operator=(const ClassName& x);. Use the copy constructor.
Assignment Operators In C++ - GeeksforGeeks
Copy constructor and Assignment operator are similar as they are both used to initialize one object using another object. But, there are some basic differences between them: Copy constructor Assignment operator It is called when a new object is created from an existing object, as a copy of the existing objectThis operator is called when an already

Copy constructors, assignment operators, - C++ Articles
A copy constructor is a special constructor for a class/struct that is used to make a copy of an existing instance. According to the C++ standard, the copy constructor for MyClass must have one of the following signatures: 1234.
Copy Constructors and Assignment Operators - Stanford University
C++ handles object copying and assignment through two functions called copy constructors and assignment operators. While C++ will automatically provide these functions if you don't explicitly define them, in many cases you'll need to manually control how your objects are duplicated.

The Copy constructor and the assignment operators are used to initializing one object to another object. The main difference between them is that thecopyconstructorcreatesaseparatememory block for the new object. But the assignment operator does not make new memory space.

The Copy constructor and the assignment operators are used to initializing one object to another object. The main difference between them is that the copy constructor creates a separate memory block for the new object. But the assignment operator does not make new memory space.
