"In order for a function or class to become a friend of another class, it must be declared as such by the class granting it access." Answer: True

Step by step solution

Understand the concept of friend functions and classes

A friend function or class in C++ is a function or a class that is given access to another class's private and protected members. This is a way to grant special access to specific functions or classes while still maintaining encapsulation.

Analyze the statement about declarations

The given statement says that "In order for a function or class to become a friend of another class, it must be declared as such by the class granting it access." This means that the class that wants to give access to its private and protected members should declare the function or class as a friend.

Determine the truth of the statement

The statement is indeed correct. In C++, a friend function or class must be declared inside the class that is granting access, using the keyword 'friend'. This signals the compiler that the function or class is allowed to access the private and protected members of the class. Conclusion:

Provide the answer

The given statement is True. In order for a function or class to become a friend of another class, it must be declared as such by the class granting it access, using the 'friend' keyword in C++.
