Create a C++ program that has 3 Stacks.

Insert, into the first stack, all the data above (which is the data of student’s names, surnames and the marks they obtain in a particular assessment)

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.
