Here is an Program of a C++ program that performs addition, subtraction, multiplication, and inversion of real number arrays, including their trace calculation, using an external header file:
matrix_ops.h
#include <iostream>
const int MAX_SIZE = 10;
class Matrix {

int rows;
int cols;
double data[MAX_SIZE][MAX_SIZE];
public:
Matrix(int r, int c);
Matrix operator+(Matrix other);
Matrix operator-(Matrix other);
Matrix operator*(Matrix other);
Matrix operator~();
double trace();
void print();

1.14 zyLab training*: One large program
Most zyLabs are designed to be completed in 20 - 25 minutes and emphasize a single concept. However, some zyLabs (such as the one large program or OLP) are more comprehensive and may take longer to complete.
Incremental development is a good programming practice and is the process of writing, compiling, and testing a small amount of code, then repeating the process with a small amount more (an incremental amount), and so on.
Suggested process to complete longer zyLabs:
- Implement Step 1 and submit for grading. Only one test will pass.
- Continue to implement one step at a time and resubmit for grading. At least one additional test should pass after each step.
- Continue until all steps are completed and all tests pass.
Program Specifications:
For practice with incremental development, write a program to output three statements as specified.
Step 1 (4 pts). Use print() to output "Step 1 complete". Submit for grading to confirm one of three tests passes.
Output should be:
Step 1 complete
Step 2 (3 pts). Use print() to output "Step 2 as well". Submit for grading to confirm two of three tests pass.
Output should be:
Step 1 complete
Step 2 as well
Step 3 (3 pts). Use print() to output "All steps now complete". Submit for grading to confirm all tests pass.

Print the computed square, then a fresh line.
On line 8, the square of the input integer is calculated incorrectly as:
userNumSquared = userNum + userNum;
Only two times the input number will be returned by the operation above. We just switch the addition operator (+) to multiplication (*) to address the error on this line.
Consequently, the instruction on line 8 should be changed to read:
userNumSquared = userNum * userNum;
On line 9, when the squared number is written, a new line is intended to be produced using the print command.

What is the purpose of Switch here? And, why are there two switches?
Answer:
Keep electrical signal undistorted: When a switch forwards a frame, it regenerates an undistorted square electrical signal. And, In a simple light circuit, it switches between connected and disconnected. In a more complex multi-way system it switches between two wires which both go to the other switch. The other switch chooses which wire is connected and which is not. So both switches can connect or disconnect the circuit, at any time.

What is a program code in the computer?Computer code, or a set of instructions or a system of rules defined in a specific programming language, is a term used in computer programming (i.e., the source code). It is also the name given to the source code after a compiler has prepared it for computer execution (i.e., the object code). Different platforms, operating systems, and uses are catered for by different coding languages.
Almost 9,000 coding languages have been developed, however, only a small number are now in use. The most widely used programming languages are Python, JavaScript, and C++. The process of translating a language into machine-readable binary commands is known as coding.

An engineering team’s new work project will shortly be bursting with many types of files and sub-project files. The team wants to be able to easily find the project files. What should it do to have the best organizational method for the project’s files?
Answer:
An engineering team can implement the following organizational methods to easily find project files:
File naming conventions: Establish a consistent and logical naming convention for all files within the project, such as using the project name and date in the file name. This will make it easier to identify and locate specific files.
File folders: Create folders for each project and sub-project, and organize the files within each folder. This will make it easy to find and access the files, and also easy to share files with team members.
Version control: Use a version control system (such as Git) to track changes to the files and keep track of different versions of the files. This will ensure that the team can access the most recent version of the files and also revert to previous versions if needed.
Cloud-based storage: Use a cloud-based storage service to store the files. This will allow team members to access the files from anywhere and collaborate in real-time.
Backups: Regularly backup the files to ensure that they are not lost in case of any technical issues.
File-sharing tools: Use file sharing tools such as SharePoint or Asana to share the files with the team and make it easy for them to access and collaborate on the files.
Document management systems: Use a document management system (DMS) to manage, store and share documents, images, videos and other files. This will provide an easy way to access, share and collaborate on the files, and also ensure that the files are stored in a secure location.
Access control: Implement access control to ensure that only authorized team members can access the files.
Explanation:
By implementing these organizational methods, the engineering team will be able to easily find and access the project files and collaborate efficiently on the project.

Explanation:
1.18 lab: winning team (classes) given main(), define the team class (in file team.java). for class method getwinpercentage(), the formula is: wins / (wins losses). note: use casting to prevent integer division. for class method printstanding(), output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. a team has a winning average if the win percentage is 0.5 or greater.
In object-oriented programming, a class is a template description of the method(s) and variable(s) of a given type of object.
How to define a Team class?
public class Team {
private String name;
private int wins;
private int losses;
// TODO: Define mutator methods -
// setName(), setWins(), setLosses()
public void setName(String name) {
this.name = name;
}
public void setWins(int wins) {
this.wins = wins;
}
public void setLosses(int losses) {
this.losses = losses;
}
// TODO: Define accessor methods -
// getName(), getWins(), getLosses()
public String getName() {
return name;
}
public int getWins() {
return wins;
}
public int getLosses() {
return losses;
}
// TODO: Define getWinPercentage()
public double getWinPercentage() {
//calculate percentage
double percentage = (double) wins / (wins + losses);
return percentage;
}
// TODO: Define printStanding()
public void printStanding() {
//call getWinPercentage() method
double percentage = getWinPercentage();
//display percentage with 2 decimal points
System.out.printf("Win percentage: %.2f", percentage);
//if percentage is greater than or equal to 0.5,then winning average
if (percentage >= 0.5)
System.out.println("\nCongratulations, Team " + name + " has a winning average!");
//otherwise losing average
else
System.out.println("\nTeam " + name + " has a losing average.");
}
}
WinningTeam class
//Adding the Scanner class to read input from users import java.util.Scanner;
public class WinningTeam {
public static void main(String[] args) {
//creating an instance of scanner class
Scanner scnr = new Scanner(System.in);
//creating an instance of team class
Team team = new Team();
//read name,wins and losses
String name = scnr.next();
int wins = scnr.nextInt();
int losses = scnr.nextInt();
//set values using setter methods
team.setName(name);
team.setWins(wins);
team.setLosses(losses);
//calling printStanding() method
