An array called number contains 20 integer values and must be filled with values in the following way:
Fill the array with consecutive even numbers starting from 10.
Start again at the first element and increase every fourth element with 3
. Replace the value of the first four elements each with its square.
Deduct 2 from the last 3 elements.
Swap the value of element 5 and element 15
. Add the value of the first element to that of the last element
Add consecutive integers (starting from 1) to all even elements. Remember, the first element has a subscript of 0 and the last element (element 20) has a subscript of 19.
The following must be displayed:
All elements must be displayed each on a new line. Identify each element clearly
. Display the highest value in the array.
The lowest value in the array must be displayed.
Count and display how many even values and how many odd values the array contains.
2.1 Study the following descriptions and write only the statements to achieve the required objectives in both algorithm and C++ syntax.
2.1.1 The array called quantity has 20 elements. Write statements that will help in counting how many of these elements have a value of less than 50. Also determine the sum of the values that are more than or equal to 50. Display these 2 answers.
2.1.2 The array called itemPrice has 150 elements. Write the statements to determine and display the highest price. If there is more than one item with this price, the number of items must also be displayed.
2.1.3Three corresponding arrays of 250 elements each contain the following respectively: employee number, department and annual salary. Write only the statements to calculate the monthly salary for each and every employee. The following must be displayed the department and employee number of every employee who earns more than R100 000 per annum.
2.1.4 Three corresponding arrays of 250 elements each contain the following respectively: employee number, department and annual salary. The following must be displayed the department and employee number as well as the monthly salary of each employee that must be stored in a fourth parallel array called monSalay.
1. Objectives
The main objective of this project is to let you know in more detail the design and description process of a Management Information Base (MIB). A simple case will be studied and treated with the formalism dictated by SMI-v2 described by RFC 1213.
2. Introduction
SMI-v2 uses only a very small subset of ASN.1 and has few templates to formally describe an information base.
RFC 1213 gives the formalism to use a description of a MIB that will be handled with the SNMP protocol. This project will therefore ask you to familiarize yourself with this RFC.
3. Presentation of the context and design of the MIB
You should design a private Management Information Base to supervise a host. The goal is to use SNMP to communicate the information to a network management application and to be able to automatically control the state, generate useful reports and possibly detect performance or security issues.
- What information would be required to manage a host?
- Distinguish between the simple variables and their types, and the tables necessary for this information base.
4. Formal description of the MIB
For this part, we will offer you a simplified MIB in the Appendix. According to an informal description, you must format this MIB in accordance with the SMI-v2 standard. Pay particular attention to how a table should be described, and to the DESCRIPTION field of each object.
- Name the module containing the MIB using the following format: studentName-StudentID-MIB,
- Choose the OID (Object Identifier) of each element,
- Define a coherent tree structure,
- Use the ASN.1 syntax for the types of the elements.
-Write the complete MIB in text format using the SMI-v2 standard (refer to the tutorial of SMI)
5. Appendix
The elements to consider for the design of the MIB are:
1- Percentage of free CPU "freeCPULoad"
2- Percentage of unallocated memory "freeMemoryLoad"
3- If the workstation is an "isWebServer" web server
4- The operating system version "version"
5- The old start date of the "lastHostReboot" system
6- The number of current users that are logged into the "usersNumber" workstation
7- A table of these users: "usersTable"
8- The user's login name, "userId"
9- The date of the opening of the session, "userLoginDate"

Compute Z-transform of the following signals along with the RoC and verify the result with MATLAB result and attach screen shot of code and results:
(a) 𝑥(𝑛) = (1/𝑅𝐹) 𝑛𝑢(𝑛) + (1/𝑅𝐿) 𝑛𝑢(𝑛)
where RF = 12 RL = 56
Also take inverse Z-transform of computed X(z) and verify the result on page as well as in MATLAB.
Part 1
As an exercise, use incremental development to write a function called hypotenuse that returns the length of the hypotenuse of a right triangle given the lengths of the other two legs as arguments. Record each stage of the development process as you go. (Downey, 2015)
After the final stage of development, print the output of hypotenuse(3, 4) and two other calls to hypotenuse with different arguments.
Include all of the following in your Learning Journal:
An explanation of each stage of development, including code and any test input and output.
The output of hypotenuse(3,4).
The output of two additional calls to hypotenuse with different arguments.
Part 2
Invent your own function that does some useful computation of your choosing. Do not copy the function from somewhere else. Use incremental development, and record each stage of the development process as you go. Finally, print output that demonstrates that the function works as you intended.
Include all of the following in your Learning Journal:
An explanation of each stage of development, including code and any test input and output.
The output of three calls to your function with different arguments.
Do Exercise 6.4 from your textbook using recursion and the is_divisible function from Section 6.4. Your program may assume that both arguments to is_power are positive integers. Note that every positive integer that has an exponent of 0 is a power of "1". This includes "0" and "1", itself.
After writing your is_power function, include the following test cases in your script to exercise the function and print the results:
print("is_power(10, 2) returns: ", is_power(10, 2))
print("is_power(27, 3) returns: ", is_power(27, 3))
print("is_power(1, 1) returns: ", is_power(1, 1))
print("is_power(10, 1) returns: ", is_power(10, 1))
print("is_power(3, 3) returns: ", is_power(3, 3))
