Operator overloading allows programmers to extend the definition of most of the built-in operators so that they may be applied to classes.

Question 2

Accepted Answer

operator

Question 3

The associativity of an operator can be modified in an overloaded operator function.

Accepted Answer

Accepted Answer

The answer of Every object maintains a hidden pointer to...

Question 5

A(n) ____________________ function is a nonmember function that has access to all the public and private variables of a class.

Accepted Answer

Accepted Answer

The answer of Which operator functions cannot be overloaded as...

Question 7

The stream extraction and stream insertion operators must be overloaded as member functions.

Accepted Answer

Stream extraction and stream insertion operators are overloaded as member functions because they need to access the private data members of the class.

Question 8

The body of an overloaded assignment operator should include self-assignments.

Accepted Answer

The body of an overloaded assignment operator should handle self-assignment to prevent issues, but it should not include self-assignments as they are redundant and can lead to errors.

Question 9

Question 11

Including multiple constructors of a class is an example of function overloading.

Accepted Answer

Function overloading allows multiple functions or constructors with the same name but different parameters within the same scope, enabling different ways to instantiate a class.

Question 12

A template instantiation can only be created with a built-in type.

Accepted Answer

Template instantiation can be created with both built-in types and user-defined types, such as classes or structs.
