Create a C++ program that has 3 Stacks.
Insert, into the first stack, all the data above
Display the content of the stack on the screen (console)
Then, remove all the students whose surname starts with the alphabets ‘R’, ‘J’ and
‘M’, from the first stack and insert them into the second Stack.
Display the contents of Stack1 and Stack2.
Finally, remove all the students whose marks are less than 50 from both Stack1
and Stack2 and insert them into the Third Stack.
Display the contents of all the 3 Stacks.
3b. Sort all the stacks in this order:
Stack1 in alphabetic order by name
Stack2 in alphabetic order by Surname
Stack3 in Numeric order (descending) by marks obtained.
