# Dr HO Coaching Centre

Dr HO Coaching Centre gives lessons on three programming languages:
Python, Java and C++. They have divided each programming language into a
number of topics such as if-statement, while-loop, and for-loop. They teach each
topic through a standard one- hour long lesson.

Students can request any number of additional hours on the topics that they have already studied. They can also request for any number of practice tests at the centre.

The centre charges for each standard lesson, additional hour and test according to the
table below.

For example, if a student studying Python requests 20 topics, 10 additional hours and 5
tests the total tuition fee for him/her will be (\$6,000 + \$2,000 + \$1250) \$9,250.

The Principal of Dr Ho Coaching Centre (Dr Wise Ho) contracts you to build a computer
system, Power of Knowledge (PK), for them in Python.
PK will ask them to input, for a student. the name Of the programming language that the
student wants to study, the number Of topics/lessons that he/she wants to study, the
number of additional hours that he/she wants to study, and the number of tests that
he/she wants to sit for. Based on the inputs the program will compute and display the
tuition fee for the lessons, additional hours and tests. It will also display the total tuition
PK will then ask Dr HO "DO you want to compute the tuition fee for another student?"
If Dr Ho wants to compute the tuition fee for another student (i.e. enters or "y" to the
question above), PK will ask for all these inputs again for the new student, and compute
and display the total tuition fee for the new student. The program will then again ask Dr
Ho "Do you want to compute the tuition fee for another student?"
The above process will continue as long as they want to compute the tuition fee for another student. However, if Dr Ho does not want to compute the tuition fee for another
student (i.e. he enters anything Other than "Y" Or "y") then the program will exit.
A typical example of the display of your program can be as
