1A: English Dictionary App

This project uses the skills learnt from week 1 to week 6.

The aim of this project is to create an English Dictionary app that returns definitions of English words.

This project uses the skills learnt from week 1 to week 6.

The aim of this project is to create an English Dictionary app that returns definitions of English words.

When the application is started, it displays a menu as follows:

Main Menu

Add a new word

Find the meaning

Update a word

Exit

Enter Choice:

If item 1 is selected, it should prompt for a word and then accept its meaning.

This pair of word and its meaning should be stored in a file called ‘words.txt’. When item 2 is selected,

it should prompt for a word, search that word in the file ‘words.txt’ and return the meaning if it is found.

If the meaning is not found, it should display an appropriate message. Similarly, when choice 3 is entered,

it should accept a word and update its meaning. In all the above three cases, the prompt should return to the main menu.

The words and their meanings should be stored as a dictionary in words.txt, using the concept of serialization.

If choice 4 is selected, a graceful exit should be performed.
