Chapter 2, Problem 1RE
Explanation of Solution
Difference between object and class:
The following table shows the difference between “object” and “class”.
| Object | Class |
| An object is an instance of a class. | A class is a category of objects. |
| An object represents an entity in the real world that can be distinctly identified. | A class uses variables to define data fields, and functions to define behaviors of the class. |
|
Object is followed by the class name. | Class name is represented with the keyword “class”. |
|
Syntax for creating an object: Classname objectname; Sample code: Circle r1; |
Syntax for defining a class: class classname { // Body of the class }; Sample code: //Declare the class class circle { Private: double radius; }; |

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
