You are tasked with developing a text$-$checking application using regular expressions. The application will allow users to load a text file through a standard file open dialog box and automatically scan for specific problematic words. These problematic words include:

$$

Words containing a number anywhere in the word.

$$

Words containing a capital letter in any position other than the start of the word.

$$

$$

Words containing special characters $($such as #$,*,/,$ @$,^,$ etc.$)$ within the word, except if the character is at the start or end of the word. A hyphen $(-)$ is considered acceptable.

Once the text file is loaded, the application should display an indication that the file has been successfully loaded. The problematic words should then be flagged, showing both the line number and the word number in the line where each issue occurs.

$($Note: The scenario is only applicable to questions $3\mathrm{.}5)$

$3\mathrm{.}5$ What is the best way to handle different types of problematic words with multiple regular expressions? Show all the regular expressions $($numbers$,$ capital letters, special characters$)(3)$

Scenario Five

You are tasked with extending an existing application to enable broadcasting the contents of a data model using User Datagram Protocol $($UDP$).$ The data should be broadcast in XML format.

This broadcasting functionality should be implemented as a thread running in the main application.

$($Note: The scenario is applicable to questions $3\mathrm{.}63\mathrm{.}7)$

$3\mathrm{.}6.$ What considerations should you take into account when broadcasting data over UDP? $(3)$

$3\mathrm{.}7.$ How would you handle the case where the UDP receiver receives partial or corrupt XML data? Also give explanation with a show of a code $(3)$
