Answer:
Explanation:
When you have a single copy, a large number of concurrent updates that are supposed to go to a file may result in the user obtaining incorrect information. This incorrect information obtained them leads to the file being left in an incorrect state. When you have a lot of or multiple copies, then storage waste exist and the various copies might happen not to be consistent with respect one other. In summary, what happens is that
a) Using one copy saves space, but also the change might have an effect on all the users.
b) Using multiple copies avoids eliminates the change problem, while creating its own problems, using more space.
A class member function that automatically initializes the data members of a class exists called a constructor.
<h3>
What is meant by member function?</h3>
Operators and functions that are designated as members of a class are known as member functions. Operators and functions declared with the friend specifier are not included in member functions. These are referred to as class pals. Together, data members and member functions describe the characteristics and actions of the objects in a Class. Data members are the data variables, and member functions are the functions used to control these variables.
In C++, there are typically five different types of member functions available. Specifically, friend member functions and basic, static, const, inline functions. Classes-only functions are member functions. Any private, protected, or public member of its class may be accessed using the public member function. Any member function of a class, not just the public ones, has access to every single other member that has been declared inside the class. so are easy to programme.
Hence, A class member function that automatically initializes the data members of a class exists called a constructor.
