# NOW TO CHECK OUT THE DIFFERENCE BETWEEN Pt.1
# AND Pt.2 TRY RUNNIG THE CODE ON THE BASIS OF
# INHERITANCE, IN OTHER WORDS TRY RUNNING ONLY
# B CLASS IN Pt.2 AND THEN RUN ONLY a2
# YOU WILL SEE A DIFFERENCE IN THE RUNNING OF
# ONLY a2,,,, IT WILL STILL SHOW THAT FEATURE 3
# AND 4 IS IN PROCESS,, THIS MEANS THAT B IS THE
