Answer: A) It is directly accessible only in B1
Explanation: In the given chunk of code, Class B1 is a base class. Class B2 is derived class of class B1. Class B3 is derived class of B2. As you can see class B1 has two members or instance variables i and j. Instance variable cannot be directly accessible by both B2 and B3. If you see this statement of the given code private int j; the keyword private is used with the variable j. This keyword is called access specifier. Access specifiers specifies how the members of a class can be accessed. These members are attributes and methods of that class. Any member of a class that are declared private cannot be inherited by derived classes of that class. Additionally these private members cannot be accessed from within any method inside derived class. So j is directly accessible only in B1. You can access a private instance variable from within the same class or can access it through the methods of class.
<u>In DBMS comparison normally end user compare the following this</u>
1. Cost effective.
2. How much storage capacity
3. Number of concurrent users or connection.
4. Extend storage capacity
<u>Explanation:</u>
Normally end users compare DBMS such as oracle, MySQL, sqlserver, MS access, and postages sql and mongo db.
If it is document oriented or image search best is mongo dB or clouch db, for best relationship management of DBMS such as oracle, MySQL server extra.
For colonial adventure tours and DBMS I would suggest either mongo dB or oracle all depends on organization.
Answer:
c = float(input("Enter the temperature in Celsius: "))
f = c * 1.8 + 32
print("The temperature in Fahrenheit: " + str(f))
k = (f - 32) / 1.8 + 273.15
print("The temperature in Kelvin: " + str(k))
Explanation:
*The code is in Python.
Ask the user to enter the temperature in Celsius
Convert the Celsius to Fahrenheit using the conversion formula and print it
Convert the Fahrenheit to Kelvin using the conversion formula and print it
