Network forensic analysis. A network forensic analyst is responsible for identifying worms, viruses, and infected nodes in the computer network. A new methodology for finding patterns in data that signify infections was investigated in IEEE Transactions on Information Forensics and Security (May 2013). The method uses multiple filters to check strings of information. For this exercise, consider a data string of length 4 bytes (positions), where each byte is either a 0 or a 1 (e.g., 0010 ). Also, consider two possible strings, named and In a simple single filter system, the probability that and differ in any one of the bytes is .5.

With the cold winter months fast approaching, Lungi wants to improve the overall effectiveness of
operations at his NGO. He wants to keep track of all the blankets he has in stock and be able to
determine how many he has left on distribution days. In the past, it has happened that Lungi thought
he had blankets to hand out but in fact had none left.
Lungi found out that you are an IT student who needs to find a client for their final year IT project. He
has volunteered to be your client.
Q.1.1 Plan the logic for Lungi’s application using pseudocode. The logic needs to satisfy
the following needs:
 The application will need to allow Lungi to enter the number of blankets he
wishes to distribute on a given day.
 The application should keep track of the number of blankets handed out to
ensure that Lungi does not hand out more blankets than he has.
 The application will need to warn Lungi when he has only one (1) blanket
left to hand out.
 Once all the blankets have been handed out, the following report should be
produced:
 The pseudocode should incorporate the use of modules.
 The pseudocode should implement the features of good program design.
 Use at least one loop structure appropriately.
 Use at least one selection structure appropriately.

A particular talent competition has five judges, each of whom awards a
score between 0 and 10 to each performer. Fractional scores, such as 8.3, are allowed. A
performer’s final score is determined by dropping the highest and the lowest score received, then
averaging the three remaining scores. Write a program that uses these rules to calculate and
display a contestant’s score. It should include the following functions:
• getJudgeData() should ask the user for a judge’s score, validate it, and then return it. This
function should be called by main once for each of the five judges.
• calcScore() should drop the highest and lowest score and then calculate and print the
average of the three scores that remain. This function should be called at least once by
main and should be passed the five scores. These averages should be rounded to the
tenths decimal place. Make sure you are rounding after your calculation (3.57 = 3.6 and
3.54 = 3.5)
Two additional functions, described below, should be called by calcScore, which uses the
returned information to determine which scores to drop.
• findLowest() should find the lowest of the five scores passed to it.
• findHighest() should find and return the highest of the five scores passed to it.
