A student in Programming 1 wants to know the surface area and volume of a cylindrical shape.
Figure 5.1: Example of a cylinder
Volume = PI(R^²) x height
Area = 2PI(R^²) x height + 2PI(R^²)
5.1.1 Write a program that will assist the students:
5.1.2Create a C++ source file called Cylinder and save it in a file called Cylinder.cpp.
5.2 Create the following functions:
5.2.1 calcVolume() This function will receive three parameters and it must then calculate
and return the volume of a cylinder using the information given
above.
5.2.2 calcArea() This function will receive three parameters and it must then calculate
and return the area of a cylinder using the information given above.
5.2.3 main() NB: The functions must be implemented above the main.
Add all necessary pre-processor directives.
Declare all constants and necessary variables.
Prompt the user for the height of the cylinder, and the radius of
the base of the cylinder.
Based on the users option :
o Do the relevant calculations by calling the correct
function.
Display the results of the desired measurement.
If an invalid option is selected an appropriate error message
and return the answer in an algorithm.
2.1.1 display determineAngle (degrees)
The function must determine and return the results if an angle is equal to 90
degrees, display the message “The angle is a right angle”; else display the
message “The angle is not a right angle”.
2.1.2 If getResults(summative1, summative2) = true
The function must determine and return results to indicate if the student has
passed or not. The student will pass the module if the final mark of one of the
summative test mark is 50 and above.
2.2 Study the following sub procedure calls and then write the complete sub procedure in
both algorithm and ++ syntax to calculate and return the answer.
2.2.1 call CalcAreaPeri(length, width, area, perimeter)
The sub procedure must calculate the area and perimeter for the rectangle which
must be accessible by the calling module. Write the complete sub procedure for
this problem.
2.3 Write the function or sub procedure and the function and/or procedure call for the
following:
2.3.1 The function must determine and return the results if the two values sent to it are
even or not. Use a selection control structure in your call statement.
2.3.2 There are three players in a match, they all have different scores. The function
must determine the best player and the name for the best player. The best player
must have 150 or more points. The calling module must display the name and the

Suppose we have a 5 x 5 image.The pixels in the top row are numbered 0 through 4 left to right,the ones in the second row from the to are numbered 5 through 9 left to right, and so on. Suppose there is a 'T' in the middle. The horizontal bar is in the middle of the second row, and 3 pixels wide. The vertical bar is in the middle of the third column and is also 3 pixels wide. Only pixels of the 'T' are black, rest are white.
Suppose we flatten the image into an array(let's call it A, and it is indexed from 0) such that pixel number i goes into the array at index i. What is the index of a pixel in column a and row b? (Note that first row has a=0 and first column has b=0)
5 * j + i
5 * j * i
5 * i + j
5 * i + 5 * j
Which of the indices in the array correspond to black pixels ?
3
8
11
13
What is the total number of white pixels?
For the pixel at index i in the array, what are the corresponding row and column number (first row has row number 0, and second row has 1)?
Note: floor(x) is the largest integer that is less than or equal to x. ceil(x) is the smallest
integer that is greater than or equal to x.
floor(i/5), i%5
i%5, floor(i/5)
ceil(i/5), i%5
floor(i/5)+1, i%5

Mobile phones are considered to be the most common communication devices in history, mobile phones are not only used for casual greetings but also, sending and receiving important data such as, social security numbers, bank account details and passwords. Public key cryptography is a proven security solution, which can be used to secure the mobile communications. ABC company have been proposed; server-based framework public key cryptography solution to secure the mobile communications. Third party servers were used to check the certificates, authenticating the communicating parties, key distribution, etc. The proposed framework consists two type of ciphers; i) Public key Cryptosystem (RSA) and, ii) decrypt messages through the digital signature. There are four scenarios to be considered order security requirement of integrity and confidentiality; based on that scenarios answer the following questions:
a. Scenario 1: Show the security design and calculation steps for digital signature by figure and explain on how to calculate?
b. Scenario 2: Based on Scenario 1, show the security design sequences and calculation steps for one-way hash algorithm by figure and provide justification on the usage of one-way hash algorithm? Then, list the Properties of Hash Algorithm?
c. Scenario 3: Based on Scenario1, show the security design sequences and calculation steps for RSA by figure and explain how to use it to distribute the keys?
d. Scenario4: Based on Scenario 3, show the security design sequences and calculation steps for private key cipher by figure and explain how to use it for encrypt and decrypt messages?
