Temperature for the month of April 2017 has been recorded by the zambia metrological department as follows : 24.0,17.5,33.0,36.5,36.0,22.5,12.5,44.0,15.5,33.0,41.5,23.5 explain in detail how these temperatures can be accessed and arranged in a 2DA matrix. Write a program to show how they can be arranged in a 3*3 matrix. Find the total sum of all the temperatures using 2DA
Answer:
The sum of the temperatures is: 336
Explanation:
2-Dimensional Array:
A two dimensional array is defined as
int temp [3] [3]
This is how a two dimensional array is defined in C++ programming language.
Here we have defined a 2-D array named temp which can store 3*3 = 9 int values
These 9 values are stored in 3 rows and 3 columns as below:
1, 2, 3
4, 5, 6
7, 8, 9
We are given the temperature for the month of April 2017 recorded by the Zambia metro-logical department.
24.0, 17.5, 33.0, 36.5, 36.0, 22.5, 12.5, 44.0, 15.5, 33.0, 41.5, 23.5
The given temperature values are 12 therefore, we would need a matrix of 3 rows and 4 columns ( 4 rows and 3 columns is also valid)
3*4 = 12 values
These 12 values will be arrange as below:
1, 2, 3, 4
5, 6, 7, 8
9, 10, 11, 12
C++ Program:
#include <iostream>
using namespace std;
int main()
{
// initialize the number of rows and columns
int row = 3;
int col = 4;
// initialize variable sum to store the sum of temperature values
int sum = 0;
// initialize 2d array with given temperature values
float temp[row][col] = { {24.0, 17.5, 33.0, 36.5}, {36.0, 22.5, 12.5, 44.0}, {33.0, 41.5, 23.5, 15.5} };
// we need two for loops to keep track of rows and columns
for(int i = 0; i < row; ++i)
{
for(int j = 0; j < col; ++j)
{
// to display individual temperature values
cout<< "temp[" << i << "][" << j << "] = " << temp[i][j] <<endl;
// to sum the elements of the 2d array
sum+=temp[i][j];
}
}
// to display the sum of temperature values
cout<<"The sum of the temperatures is: "<<sum<<endl;
return 0;
}
Output:
temp[0][0] = 24
temp[0][1] = 17.5
temp[0][2] = 33
temp[0][3] = 36.5
temp[1][0] = 36
temp[1][1] = 22.5
temp[1][2] = 12.5
temp[1][3] = 44
temp[2][0] = 33
temp[2][1] = 41.5
temp[2][2] = 23.5
temp[2][3] = 15.5
The sum of the temperatures is: 336
Note:
The index start at 0 not 1 that is why you see rows from 0 to 2 and columns from 0 to 3.
John recently worked on a project about various programming languages. He learned that though procedural language programs are useful, they have disadvantages too. What is a disadvantage of programs written in procedural languages? A. Programs do not represent data complexity. B. Programs take more time to execute. C. Programs are prone to security threats. D. Programs do not interface with multiple platforms.
Answer:
Option A Programs do not represent data complexity.
Explanation:
In procedural languages like C, it doesn't support object oriented design that could encapsulate data in an object that entails a set of relevant attributes and methods which can represent an entity in real life better. This means the procedural language is limited by creating an object-like data structure that can represent data complexity. The procedural language only support the running a program by following a set of instructions in order.

audience
color scheme
dynamic tension
goals
Answer:
• Audience
• Goals
Explanation:
Trevor works for many different clients and creates a wide variety of business publications. The two factors in the list below have the most influence over his layout designs are:
a) Audience
From the above question,we can see that Trevor creates different publications for different clients. This is because, the taste, wants or desires of each clients varies. It is not the same. Therefore, the layout of his publication is influence by the target audience that the publication is meant for.
For example, a client may want a publication with big fonts because the target audience who would be reading the publication are elderly people.
Another clients may want his publication designed with smaller fonts and a unique font style.
It is Trevor's duty to make sure that he caters to the needs his client's target audience by satisfying their desires, however different they may be.
b) Goals
The goals of the publication is one of the things that can influence the layout design of Trevor's publication. Let's take for example, a client is creating a publication to reach the teen society, probably a publication on pop music or fashion, this is the goal. Trevor would have to create the publication such that it attracts teens. The layout of the publication would have to come in catchy colours, interesting fonts, musical symbols that would catch the eye of teens and make them want to read such publication.

1...difference between repeater and hub .
2... difference between bridge and router .
Answer:
Explanation:I don't say you have to mark my ans as brainliest but if you think it has really helped you plz don't forget to thank me..
1. A repeater amplifies and extends signals, while a hub is a multi-port device that broadcasts data to all connected devices, creating a shared collision domain.
2. A bridge connects network segments at the data link layer and forwards packets based on MAC addresses, while a router connects networks at the network layer and forwards packets based on IP addresses.
1. Difference between a Repeater and a Hub:
Repeater:
Operates at the physical layer (Layer 1) of the network.
Regenerates and amplifies network signals to extend their reach and overcome signal degradation.
Does not inspect or manage network traffic.
All devices connected to a repeater share the same collision domain.
Transparent to network protocols and does not interpret data.
Hub:
Operates at the physical layer (Layer 1) of the network.
Multi-port device that broadcasts incoming data to all connected devices.
Creates a single collision domain, causing devices to contend for network bandwidth.
Lacks intelligent traffic management and filtering capabilities.
Limited in terms of network performance and scalability due to shared bandwidth
2. Difference between a Bridge and a Router:
Bridge:
Operates at the data link layer (Layer 2) of the network.
Connects and joins separate network segments or LANs to form a single logical network.
Forwards data packets based on MAC addresses.
Builds and maintains a table (MAC table) of MAC addresses and associated network interfaces.
Bridges are commonly used to reduce network congestion and improve performance within smaller networks.
Does not perform IP address-based routing.
Router:
Operates at the network layer (Layer 3) of the network.
Connects multiple networks and routes data packets between them based on IP addresses.
Determines the best path for packet delivery using routing tables and protocols (e.g., RIP, OSPF, BGP).
Performs network address translation (NAT) and offers features like firewall and network traffic management.
Enables communication between networks with different IP address schemes.

Discuss the evolution of file system data processing and how it is helpful to understanding of the data access limitations that databases attempt to over come
Answer:
in times before the use of computers, technologist invented computers to function on disk operating systems, each computer was built to run a single, proprietary application, which had complete and exclusive control of the entire machine. the introduction and use of computer systems that can simply run more than one application required a mechanism to ensure that applications did not write over each other's data. developers of Application addressed this problem by adopting a single standard for distinguishing disk sectors in use from those that were free by marking them accordingly.With the introduction of a file system, applications do not have any business with the physical storage medium
The evolution of the file system gave a single level of indirection between applications and the disk the file systems originated out of the need for multiple applications to share the same storage medium. the evolution has lead to the ckean removal of data redundancy, Ease of maintenance of database,Reduced storage costs,increase in Data integrity and privacy.

Phillip is using an optical device to look at the stars. He knows that it uses mirrors, but cannot remember its name. He is using a ......
refracting telescope
reflecting telescope
refracting microscope
reflecting microscope
EXPLAIN WHY YOU CHOOSE THAT ANSWER
Answer:
He is using a REFLECTING TELESCOPE.
Explanation:
A telescope is an optical instrument that is used by scientists or astronomers to view objects that are very faraway such as objects that are in space. For example: the galaxies, the stars, the moon, the planet e.t.c.
The mode of operation of a telescope is, a telescope makes use of either a lens or mirrors which are curved. This lens or mirrors focus the light rays from the faraway objects and uses them to form an image.
We have two types of telescopes.
a. Refracting Telescope: Another name for a refracting telescope is a refractor. The refracting telescope uses a lens to focus the rays of light and form an image.
b. Reflecting telescope: This is also called a reflector. It is different from the refracting telescope because it makes use of curved mirrors to focus the rays of light and form an image. The images formed by reflecting telescopes are very big and clear. Those images are also free from any form of abberation such as chromatic abberation.
From the above question, Phillip is using an optical device to look at the stars. He knows that it uses mirrors, but cannot remember its name. He is using a REFLECTING TELESCOPE. The reason for my answer is because it is said in the question that the optical device makes use of mirrors and it is only a reflecting telescope that uses mirrors.
