Must parameter of assignment operator be reference?
- by Tim
When overloading assignment operator of a class in C++, must its parameter be reference?
For example,
class MyClass {
public:
...
MyClass & operator=(const MyClass &rhs);
...
}
Can it be
class MyClass {
public:
...
MyClass & operator=(const MyClass rhs);
...
}
?
Thanks!
