Define class Person: The program must accept the details of a person(name & age) based on the query Q as the input. The program must print the output based on the following conditions.
– The default name of the person is “person” and the age is 0.
– If the query is 1, then the program must print the default values of the name and age separated by a colon.
– If the query is 2, then the program must print the given name and the default value of the age separated by a colon.
– If the query is 3, then the program must print the given name and age separated by a colon.
Your task is to define the class Person so that the program runs successfully.
Note: The query value can be 1 or 2 or 3.
