Given a char variable c that has already been declared, write some code that repeatedly reads a value from standard input into c until at last a 'Y' or 'y' or 'N' or 'n' has been entered.

Answers

Answer:  

The code to this question as follows:  

Code:  

do{ //do-while loop  

cin >> c; //input value from user.  

}while (!(c == 'Y' || c == 'y' || c=='N' || c == 'n')); //check condition.  

Explanation:  

The description of the code as follows:  

In this code, we use a do-while loop. It is an exit control loop. In the loop, we use the char variable that is "c" this variable is used for user input. End of the loop we define the condition that is variable c value is not equal to "y", "Y", "n" and "N".  In the loop, we use OR operator that means if any of the above conditions is match it will terminate the loop.  

Final answer:

A while loop can be used to repeatedly read a char variable from standard input until 'Y', 'y', 'N', or 'n' is entered, utilizing a do-while loop to check the condition after each input.

Explanation:

To repeatedly read a value into a char variable c until 'Y', 'y', 'N', or 'n' is entered, one could use a while loop in the following way:

#include
using namespace std;

do {
   cin >> c;
} while (c != 'Y' && c != 'y' && c != 'N' && c != 'n');

This code snippet uses a do-while loop to ensure that the body is executed at least once before checking the condition. If the character entered is not 'Y', 'y', 'N', or 'n', it repeats the prompt, continuing to read the next standard input into variable c. When one of these specific characters is entered, the loop terminates.

Which of the following characteristics of an e-mail header should cause suspicion?A. Multiple recipientsB. No subject lineC. Unknown Sender

Answers

Final answer:

Suspicion may arise from an e-mail header if there is no subject line, the e-mail has multiple recipients, or it originates from an unknown sender, as these could indicate a spam or a phishing attempt.

Explanation:

In evaluating which characteristics of an e-mail header should cause suspicion, there are several tell-tale signs to consider. An e-mail header that flags suspicion may include characteristics such as a lack of a subject line, which leaves recipients clueless about the content without opening the e-mail, potentially indicating a lack of specificity or that the sender is trying to avoid detection by spam filters. .

Additionally, multiple recipients can be a red flag, especially if the email is sent to recipients en masse without a clear reason. Furthermore, an e-mail from an unknown sender should always be approached with caution, as it can be a common tactic used in phishing attacks or spam. It is essential to critically evaluate these characteristics to ensure your cybersecurity.

Over a TCP connection, suppose host A sends two segments to host B, host B sends an acknowledgement for each segment, the first acknowledgement is lost, but the second acknowledgement arrives before the timer for the first segment expires. True or False.

Answers

Over a TCP connection, suppose host A sends two segments to host B, host B sends an acknowledgement for each segment, the first acknowledgement is lost, but the second acknowledgement arrives before the timer for the first segment expires is True.

True

Explanation:

In network packet loss is considered as connectivity loss. In this scenario host A send two segment to host B and acknowledgement from host B Is awaiting at host A.

Since first acknowledgement is lost it is marked as packet lost. Since in network packet waiting for acknowledgement is keep continues process and waiting or trying to accept acknowledgement for certain period of time, once period limits cross then it is declared as packet loss.

Meanwhile second comes acknowledged is success. For end user assumes second segments comes first before first segment. But any how first segment expires.

Answers

Answer:

The answer to this question is option "C".

Explanation:

The stack is part of the data structure. In this stack perform two operations that are "push and pop". The push function is used to push(insert) and pop function is used to pop(delete) elements on the stack. It follows the LIFO process that stands for last in first out.

In this code, firstly we insert three elements on the stack that is "a, b and c". Then, we insert two elements on the stack that is "d and e", in this element store in the upper part of the stack and then we call pop function two times. In first time, the call will remove elements e and the second time it will remove element d.

That's why the answer is option "C".

The general syntax for the function prototype to overload the assignment operator = for a class is ____.a. friend className& operator=(const className&);b. const className& operator=(const className&);c. className& operator=(className&);d. string className& operator=(className&);

Answers

Answer:

Option (B) is the correct answer to the following question.

Explanation:

Here, in the code "const" is the constant keyword which is used when we need that the value stored in that variable will never change.

The following option is correct because the assignment operator are those operator which initialize the value in the variable and overloading of the assignment operator would be as we use the other operators and also we could use them by creating the objects as we use in the copy constructor.

a. It is impossible to predict
b. int! double!
c. Duplicate function names results in a compiler error.
d. double! int!

Answers

Answer:

The correct answer to the following question is option "b".  

Explanation:

The method having the same name but the arguments have different so it is called method overloading. It is a part of the object-oriented programming language (oops).  

In the given code we define same method two times that is "mystery()". but in this method, we pass two different parameters. For the first time, we pass a double variable that is "a" as a parameter. In the second time, we pass an integer variable that is "a" as a parameter and in both functions, we write some codes. In the calling time, we call function two times. In first time calling we pass an integer value that is "1" and second time calling we pass double value that is "1.0". So the output of this code is "int! double!".  

That's why the option "b" is correct.

Explanation:

In the given question code we use the array list that does not store any value in the index 0, because for adding elements in the list, we use add function. In this function parameter, we pass the value that is "i+3". Which means the value of i is increased by 3. In option A, B and C we do not assign any value in the add function. so, it not correct.
