Application Kata “More”
Write a console application to display the content of a text file in a pagewise manner. It should be called like this:
Upon start the first page is shown (page length = 20 lines) and the application waits for the user to press a key to show the next page. Pressing [Esc] exits the application. Example:
C:> more kublaakhan.txt In Xanadu did Kubla Khan A stately pleasure-dome decree: … As if this earth in fast thick pants were breathing, A mighty fountain momently was forced: --- Press any key to show next page. Exit by pressing [Esc] ---
After pressing for example the space bar this would be displayed:
Amid whose swift half-intermitted burst Huge fragments vaulted like rebounding hail, … A damsel with a dulcimer In a vision once I saw: --- Press any key to show next page. Exit by pressing [Esc] ---
Allow for a user defined page length, e.g.
C:> more coleridge.txt 10
Show the current page number and the total number of pages at the top of each page, e.g.
C:> more kublaakhan.txt --- Page 1 of 3 --- In Xanadu did Kubla Khan A stately pleasure-dome decree: …
