Create an email address from a name

This a problem set for you to work through

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

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

What is this problem set trying to do

In this example we are primarily learning about strings and processing user input.

The Problem

This problem set is used with enormous gratitude from CS50

Design and implement a program, that, given a person’s name, prints an email address.

1. Your program will ask for a full first and full last name
2. Your program will then create an email address with the following rules:
   1. the first letter of the email shall be the lower case first letter of the users first name. For example, Bill MacKenty would result in a 'b' here.
   2. the next string of characters shall be the full last name, all lowercase with no spaces For example, Bill MacKenty, would result in 'mackenty'.
   3. the suffix would then be added to the string: '@aswarsaw.org'.

Unit Tests

• User Input: Name: Bill MacKenty
• Expected output: bmackenty@aswarsaw.org

• User Input: Name: Jan Nowak
• Expected output: jnowak@aswarsaw.org

• User Input: Name: Buzz Lightyear
• Expected output: blighyear@aswarsaw.org

Hacker edition

In the hacker version:

1. Ask the user for their year of graduation and add that to the start of the email.
   1. for example, if a student graduates in 2019, and their full name is Bill MacKenty, the output would be: 19bmackenty@aswarsaw.org

How you will be assessed

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?

#This program inputs first name, last name , graduation year(if applicable) then it ouputs the ASW email
#It will use the same system as ASW (i.e. Hung Cuong Nguyen Duc graduating 2020 will be 20nguyenduc_h@aswarsaw.org)
