Therefore, Contract is the correct option.

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.

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:

// here is code in c.

#include <stdio.h>

// main function

int main()

{

// variable to store year

int year;

printf("enter year:");

// read the year

scanf("%d",&year);

// if year>=2101

if(year>=2101)

{

printf("Distant future");

}

//if year in 2001-2100

else if(year>=2001&&year<=2100)

{

   printf("21st century");

}

//if year in 19011-2000

else if(year>=1901&&year<=2000)

{

  printf("20th century");

}

// if year<=1900

else if(year<=1900)

{

  printf("Long ago");  

}

return 0;

}

Explanation:

Read the year from user.After this, check if year is greater or equal to 2101 then print "Distant future".If year is in between 2001-2100 then print "21st century".If year is in between 1901-2000 then print "20th century".Else if year is less or equal to 1900 then print "Long ago".

Output:

enter year:2018

Client server architecture

In this set up, the servers are workstations which perform computations or provide services such as print service, data storage, data computing service, etc. The servers are specialized workstations which have the hardware and software resources particular to the type of service they provide.

Examples

1. Server providing data storage will possess database applications.

2. Print server will have applications to provide print capability.

The clients, in this set up, are workstations or other technological devices which rely on the servers and their applications to perform the computations and provide the services and needed by the client.

The client has the user interface needed to access the applications on the server. The client itself does not performs any computations while the server is responsible and equipped to perform all the application-level functions.

The clients interact with the server through the internet.

Clients can be either thin client or thick (fat) client.

The differences in them are described below.

1. Thin client, as per the name, performs minimal processing. Thick or fat client has the computational ability necessary for the client.

2. The thin client possesses basic software and peripherals and solely relies on the sever for its functionalities. Fat client has the resources needed to do the processing.

3. The user interface provided by the thin client is simpler and not rich in multimedia. The user interface provided by the fat client is much better and advanced.

4. Thin client relies heavily on the server. Fat client has low dependency on the server.

5. In the thin client set up, servers are present in more number. In this set up, servers are present in less number.

6. Each server handles a smaller number of thin clients since all the processing is done at the server end. Each server handles more thick clients since less processing is done at the server end.

Answer:

d.)either handle the exception or have a throws clause listed in the method header

Explanation:

A checked exception that can be thrown in a method , necessarily needs to be handled in the method in one of the two ways:

For example, let us see both:

a)

public void mymethod(){

// Exception handling using try/catch block

  try{

  }

  catch ( IOException e){

  }

}

b)

public void mymethod() throws IOException{

   // Exception in the throws clause

}

Answer:

d) b and c are both true.

Explanation:

The purpose of def keyword in python is to indicate start the function and it also indicates that the piece of code following the def keyword is to stored so that it can later be used in the program.

For ex:

def check(n):

   if n==10:

       return True

   return False

n=int(input("Enter an integer\n"))

if check(n):

   print("n is 10")

else:

   print("n is not 10")

In the above written code the function check is defined by using the keyword def.It also tells the interpreter to store the code because we will need it in future.

The correct option is (d) b and c are both true.

When The main purpose of the def keyword in python is to indicate the start of the function and also it indicates that the piece of code following the def keyword is to be stored so that it can later be used in the program.

For ex:

After that def check(n):

Then if n==10:

Now the return True

return False

After that n=int(input("Enter an integer\n"))

Then if check(n):

Now, print("n is 10")

else:

print("n is not 10")

In the above-written code that is the function of the check is defined by using the keyword def. It also tells the interpreter to store the code because we will need it in the future.

Explanation:

A controlled private network that can be used for information exchange by using internet technology and the telecom system of the public.

It allows the outside user with authentication to partially access the network for business information exchange securely.

Thus companies encourage the suppliers to use extranets to share information or operations related to a business so as not to lag behind in the technologically competitive era.

Companies actually encourage their suppliers to join their extranets as it can streamline communication, enhance collaboration, and improve efficiency in the supply chain. The statement is false.

Extranets are secure networks that extend internal company resources to external parties like suppliers, enabling shared access to information and data.

However, many companies may not actively encourage suppliers to join their extranets due to concerns over data security, privacy, and the complexity of managing external access.
