Explanation:

A bug in software is a coding error. The effects are often unexpected and affect the way a programme works, often resulting in the programme not functioning in the way it was intended. There are various reasons that bugs can exist in software, including (but not limited to) the following:

Final answer:

Software has bugs due to the complex nature of writing and integrating numerous lines of code, and the limitations of computer calculations. These bugs provide opportunities for learning and improving through good programming practices and debugging strategies. Quality assurance plays a key role in identifying potential bugs, helping to create more reliable software.

Explanation:

Software bugs are a common occurrence and they stem from a variety of sources. Writing software is a complex process, involving numerous lines of code, and the interaction between these lines can sometimes produce unexpected results, known as bugs. Consider bugs as an opportunity for growth; they provide a chance to learn and improve the software. Quality Assurance (QA) teams are essential in this process, constantly trying to break the software to identify potential issues. Good programming practices and debugging are critical in making the software more reliable. However, due to the complexity of software and limitations such as the accuracy of floating-point calculations, it's hard to eliminate all bugs.

It is important to proactively think about errors during development by asking, "What could go wrong here?" Moreover, implementing unit testing, which involves testing small, isolated parts of the program, helps identify and fix bugs early on. Nevertheless, as programs grow in size and complexity, the likelihood of bugs increases, making the debugging process more challenging.

Simplifying the program can sometimes be the best strategy when faced with a complex bug situation. It allows the developer to strip down to the basics and tackle issues one at a time. Remember, bugs are inevitable, but with careful testing and professional practices, their impact can be minimized, maintaining the credibility of software output.

Answer:

The three hints for the computer system design is that:

Answer:

// import package

import java.util.*;

// class definition

class Salary

{

   // method to calculate weekly salary

   public static double fun(int p_rate,int r_hour,int o_hour)

   {

       // calculate weekly salary

       double w_salary=(p_rate*r_hour)+(o_hour*p_rate*1.5);

       // return salary

       return w_salary;

   }

   // main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // object to read value from user

    Scanner scr=new Scanner(System.in);

       System.out.print("enter hourly pay rate: ");

       // read hourly pay rate

       int p_rate=scr.nextInt();

       System.out.print("enter regular hours: ");

       //read regular hours

       int r_hour=scr.nextInt();

       System.out.print("enter overtime hours : ");

       // read overtime hours

       int o_hour=scr.nextInt();

       // call the method

       System.out.println("weekly salary of an employee :"+fun(p_rate,r_hour,o_hour));

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read hourly pay rate, regular hours and overtime hours from user.Call the method sal() with these parameters.There weekly salary is calculated by multiply regular hours with p_rate and overtime hours with 1.5 time of p_rate.Sum both of them, this will be the weekly salary.return this to main method and print it.

Output:

enter hourly pay rate: 50                                                                                                  

enter regular hours: 35                                                                                                    

enter overtime hours : 15                                                                                                  

weekly salary of an employee :2875.0

The `Salary` application prompts the user for hourly pay rate, regular hours, and overtime hours, then calculates and displays the weekly salary using a separate method to calculate overtime pay.

Here's the Java program `Salary.java` that calculates and displays the weekly salary for an employee:

import java.util.Scanner;

public class Salary {

   public static void main(String[] args) {

       Scanner scanner = new Scanner(System.in);

       // Prompt the user for input

       System.out.print("Enter hourly pay rate: ");

       double hourlyPayRate = scanner.nextDouble();

       System.out.print("Enter regular hours: ");

       double regularHours = scanner.nextDouble();

       System.out.print("Enter overtime hours: ");

       double overtimeHours = scanner.nextDouble();

       // Calculate and display the weekly salary

       double weeklySalary = calculateWeeklySalary(hourlyPayRate, regularHours, overtimeHours);

       System.out.println("Weekly salary: $" + weeklySalary);

       scanner.close();

   }

   // Method to calculate overtime pay

   public static double calculateWeeklySalary(double hourlyPayRate, double regularHours, double overtimeHours) {

       double regularPay = regularHours * hourlyPayRate;

       double overtimePay = overtimeHours * hourlyPayRate * 1.5;

       return regularPay + overtimePay;

   }

}

Explanation:

You can compile and run this program to calculate and display the weekly salary for an employee based on the provided hourly pay rate, regular hours, and overtime hours.

Explanation:

The argument is for the right braces.The right braces are used for simplicity.The right brace always terminates a block of code or a function.

The argument against right brace is that when we see a right brace in a program,we are not obvious about the location of the corresponding left brace because all or multiple  statement end with a right brace.

Final answer:

Java's use of right braces to end compound statements ensures clear visual demarcation and structured code. However, it can also introduce syntax errors if not used correctly and limits coding style flexibility. The strict syntax provided by braces can be beneficial in preventing logic errors, especially when used with consistent indentation and statement-ending semicolons.

Explanation:

Using a right brace { } in Java to mark the end of compound statements is a design choice with its own set of pros and cons. One of the arguments in favor of this approach is the visual clarity it provides. With braces, it is immediately evident where a block of code begins and ends, which can be especially helpful with nesting multiple layers of logic and scopes within each other. Proper use of braces in conjunction with consistent indentation practices can greatly enhance the readability of the code.

On the other hand, there are some arguments against the obligatory use of braces, primarily focused on the potential for errors and the rigidity it imposes on coding style. For instance, if a programmer forgets to include a closing brace or places it incorrectly, it can lead to a syntax error. Furthermore, this requirement enforces a certain structure which might reduce the flexibility that programmers have in laying out their code, as seen in languages like Python which uses indentation rather than braces to denote blocks of code.

Additionally, in languages like JavaScript, omitting braces for single-line control structures is permissible, which can lead to more concise code but also introduces the potential for inconsistently coded programs and harder to detect logical errors. Therefore, while using braces imposes a strict syntax, it can prevent some types of logic errors that might occur when they are optional. The use of semicolons (;) at the end of each statement is another syntactic rule that complements the use of braces, indicating the end of one statement and the start of another.
