Answer:
(3) option is the correct answer.
Explanation:
Constructors need to initialize the object in the memory. "To declare the Constructor for any class the user needs to specify the constructor name which is already the class name". This is an object-oriented language guideline.
It is because the object is created by the name of the class and Constructor is used to allocate the memory for the object. hence Constructor is created by the name of the class.
For example--
class test //class name test
{
test() //created a constructor with class name "test"
{
}
}
In the above example class name and constructor name are same if it not then it will gives a error.
Another option is not valid for the answer to the above problem because-
- Option 1 is wrong because, for any class, the data member is a type of variable, which is used to store the data and is accessed with the help of an object.
- Option 2 is wrong because, for any class, member function is a type of user function used to accessed the variable and expressions.
- Option 4 is wrong because, package is a set used to hold classes and interfaces.
A raid 1 and mirrored system writes data on two or more disks simultaneously, thereby creating a complete copy of all the information on multiple drives.
<h3>What is Disk mirroring?</h3>
In data storage, disk mirroring is a term that connote the doubling of logical disk volumes into a different physical hard disks so that it will always be available.
Conclusively, Note that this is mostly used in RAID 1. A mirrored volume is known to be full logical depiction of separate volume copies and as such the answer above is correct.

Answer:
n computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support basic data types of integernumbers (of varying sizes), floating-point numbers (which approximate real numbers), characters and Booleans. A data type constrains the values that an expression, such as a variable or a function, might take. This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored. A data type provides a set of values from which an expression(i.e. variable, function, etc.) may take its values.[1][2]
