Example Problem Set: Difference between revisions

Latest revision as of 07:40, 14 March 2018

This a problem set for you to work through ^[1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

to build your skill applying computational thinking to a problem
to assess your knowledge and skills of different programming practices

What is this problem set trying to do[edit]

This is example problem set. In this example we are learning about lists, conditionals, and processing user input.

The Problem[edit]

At a prestigious international school, we have only 5 administrators, Michael, Carol, Jen, Constance and TJ. Your program should ask the user to type in their name. If their name matches one of our administrators, your program must output a special greeting. If the user input is any other name (does not match the list of administrators) your program should simply output a simple greeting.

There is no testing for user input. That is, if a user enters a number, an integer, or nothing, your program should not evaluate the input.

Unit Tests[edit]

User Input: Name: Bill
Expected output: Hello Bill

User Input: Name: TJ
Expected output: An administrator! Hello TJ

User Input: Name: 123
Expected output: Hello 123

Hacker edition[edit]

In the hacker version:

Your program should test for valid user input. The user input should be only allow for strings

THIS PART ISNT DONE YET

How you will be assessed[edit]

Your solution will be graded using the following axis:

Scope

To what extent does your code implement the features required by our specification?
To what extent is there evidence of effort?

Correctness

To what extent did your code meet specifications?
To what extent did your code meet unit tests?
To what extent is your code free of bugs?

Design

To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
To what extent is your code eliminating repetition?
To what extent is your code using functions appropriately?

Style

To what extent is your code readable?
To what extent is your code commented?
To what extent are your variables well named?
To what extent do you adhere to style guide?
