To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Member Function - This option is correct. Constructors are member functions of a class that are used to initialize objects of that class.
Option B) Same name as Class name - This option is correct. Constructors have the same name as the class they belong to.
Option C) Default constructor initializes all non-initialized fields and variables to zero - This option is correct. If we do not provide a constructor for a class, the compiler automatically adds a default constructor that initializes all non-initialized fields and variables to their default values, which is zero for numeric types.
Option D) Compiler adds an empty constructor if we do not write our own constructor - This option is correct. If we do not provide any constructors for a class, the compiler adds a default constructor (which is an empty constructor with no parameters) to the class.
Therefore, all of the options A, B, C, and D are true about constructors.
The correct answer is A, B, C, and D. These options are correct because constructors are member functions, have the same name as the class, the default constructor initializes non-initialized fields to zero, and the compiler adds an empty constructor if we do not write our own constructor.
