Conversion of type is a way of changing an entity from one data type to another. It is used to make the variable process properly by a function in computer coding.
In the C++ language, the result of the multitype value added or any other option is the result between those variables as a large type at that time, that's why choice b is correct.

D) use SQL or graphical tools to query the database
Explanation:
To query the database using SQL or graphical tools will help Howie to retrieve bulk of records from the database according to his requirements and it will help to understand and work with the data in a better way than using the data in raw form.
SQL is a language of database used to manipulate and manage the data in the relational database and to query the database.
It is an easy and faster way to query using SQL or graphical tools because no coding is required here.
Different graphical tools are used to present the data in the database in a way that can be easily understood by a person. Different interfaces are provided to visualize the database tables or schema diagrammatically e.g in the form of graphs etc. Different views of the database can be provided to different users according to their requirement and what information they required to be presented.
Answer:
Here is the constructor:
public Square(double s)
{ //constructor name is same as class name
sideLength = s; } //s copied into sideLength field
Explanation:
The above constructor is a parameterized constructor which takes a double type variable s as argument. The name of constructor is same as the name of class.This constructor requires one parameters. This means that all declarations of Square objects must pass one argument to the Square() constructor as constructor Square() is called based on the number and types of the arguments passed and the argument passed should be one and of type double.
Here is where the constructor fits:
public class Square {
private double sideLength;
public Square(double s)
{
sideLength = s; }
public double getArea() {
return sideLength * sideLength;}
public double getSideLength() {
return sideLength; } }
