The declaration and initialization of arrays involves creating and using the arrays
How to declare an array?Assume the programming language is Java.
To declare and initialize an array, we make use of:
One dimensional array: Data-Type Array-name [] = {List of array values}Two dimensional array: Data-Type Array-name [] [] = {List of array values}Assume the array name of the one dimensional array is num, and the data type is integer.
The following can be used to declare and initialize the array to have 5 elements
int num [] = {1,2,3,4,5}
Assume the array name of the two dimensional array is num, and the data type is integer.
The following can be used to declare and initialize the array to have 2 rows and 3 columns
int num [][] = {{1,2},{3,4},{5,6}}

Write a program that allows two players (player X and player O) to play a game of tic-tac-toe. Use a two- dimensional char array with three rows and three columns as the game board. Each element of the array should be initialized with an asterisk (*). The players take turns making moves and the program keeps track of whose turn it is. Player X moves first. The program should run a loop that:
#include <iostream>

Explanation:
a) Explain any two problems associated with the existing system used by the organization. (25 marks)
Answer:
Lack of Strategy
Many of the most common MIS issues can be traced back to a lack of a solid strategy. Information systems leaders are well aware of the many tools available to gather data on their network. But putting that information to use is often a challenge.
At one time, technology departments served as a separate operation, providing tech support and keeping an organization’s server equipment running. Today, MIS leadership often sits alongside other business leaders, working together to ensure that the technology being used supports the overall mission of the company moving forward.
Meeting Organizational Needs
MIS plays an ever-increasing role in organizations, with professionals relying on technology for every aspect of operations. Sales and marketing rely heavily on customer relationship software to track client interactions, for instance, while accounting needs its own software for billing, invoicing and financial tracking.
With more than half of all companies now relying on big data analytics, MIS is playing an even more important role. Before making a decision, today’s management teams are likely to pull reports on existing activity to ensure they use facts rather than make educated guesses.

How many bytes can be stored in a 4gb flash drive
Answer:
4,294,967,296; theoretically
Explanation:
There is 1024 bytes in a kb, 1024 kb in a mb, 1024 mb in a gb.
So we can use 1024³ as a multiplier to convert gb->byte.
1024³ * 4 = 4,294,967,296 bytes.

In this lab, you will implement a temperature converter in JavaScript. The user may type a temperature in either the Celsius or Fahrenheit textbox and press Convert to convert the temperature. An image displays based on the converted temperature. (see the image uploaded here)
Use the knowledge in computational language in JAVA to write a code that convert the temperature.
How do I convert Celsius to Fahrenheit in Java?So in an easier way we have that the code is:
Fahrenheit to celsius:/* When the input field receives input, convert the value from fahrenheit to celsius */
function temperatureConverter(valNum) {
valNum = parseFloat(valNum);
document.getElementById("outputCelsius").innerHTML = (valNum-32) / 1.8;
}
Celsius to Fahrenheit:function cToF(celsius)
{
var cTemp = celsius;
var cToFahr = cTemp * 9 / 5 + 32;
var message = cTemp+'\xB0C is ' + cToFahr + ' \xB0F.';
console.log(message);
}
function fToC(fahrenheit)
{
var fTemp = fahrenheit;
var fToCel = (fTemp - 32) * 5 / 9;
var message = fTemp+'\xB0F is ' + fToCel + '\xB0C.';
console.log(message);
}
cToF(60);

The following code appears in a sort function. Will this function sort in increasing order (smallest first) or decreasing order (largest first)? Explain your answer if (list[index] < list[index + 1]) { temp = list [index]; list[ index] = list [index +1]; list[index +1] = temp; }
A sort function sorts in an ascending or desceding order
The true statement is that the function would sort in decreasing order.
What is a sort function?A sort function is a code segment that is used to reorder a list in ascending or descending order, when called or evoked
The order of the sort functionThe code segment is given as:
if (list[index] < list[index + 1]) {
temp = list [index];
list[ index] = list [index +1];
list[index +1] = temp;
}
In the above code, we can see that the code compares a list element with the next element on the list, and the larger value comes to the front
This means that the sort function sorts in decreasing order

What does the standard deviation of a set of data tell you?
O A. The smallest data value
B. Whether the data are spread out or not
O C. How many data points there are
O D. The maximum value of the data
SU
Answer: It tells us about how our set of data is spread out as compared to our mean or expected value.
Explanation: Note: Standard deviation is represented by Greek Letter sigma.For example: A teacher in a class of particular students takes a learning ability test from the students. Average or mean marks of students is 52 with +/- 10 marks. Then 1σ (Sigma = standard deviation) it means 1 standard deviation = 68% students will lie in between 52 + 10 =62 marks and 52-10 = 42 marks region. 2σ (2 standard deviation) means among the students 95% of them will lie between 52 + 20 =72 and 52-20= 32 marks region.3σ (3 standard deviation) means 99.7% of the students will lie in the region where 52 + 30 = 82 and 52 – 30 = 22 marks region. So for 3σ (3 Standard Deviations), only 0.3% of the total students deviate +/-30 marks from the average. It means 0.15% students will have marks less than 22 and 0.15% students will have marks greater than 82. In the schematic attached, I have tried to make you understand through a diagram. Please refer to the schematic 1. It tells us about the how our set of data is spread out as compared to our average or mean. And distance from mean can be calculated through number of standard deviations that the data is how much below or above the average.For example:For 1σ 68% students will come under the curve of “Average Learners” and rest of 32% will come under the curve of “Poor Learners” and “Very Talented Learners”.For 2σ 95% of the students will come under the curve of “Average Learners” and rest will come under the curve of “Poor Learners” and “Very Talented Learners”.For 3σ 99.7% of the students will come under the curve of “Average Learners” and rest of 0.3% will come under the curve of “Poor Learners” and “Very Talented Learners”.
