This morning you modified five large data files in your home folder in Linux, and now you want to find and delete the files because you no longer need them. Which of the following commands can you use to list and sort files based on the time they were modified
Answer:
ls -t
Explanation:
"ls" command in Linux is used very often. It lists the directory contents. The "ls" utility is part of the core utilities and installed in all Linux distributions.
When ls command is used with "-t" , "ls -t" sorts files/directories list by date created or modified.
More advanced version is "ls -lt", where it sorts by date and shows info about directory, size, modified date and time, file or folder name and owner of file and its permission.
In JAVA,
Given:
1-an int variable k,
2-an int array currentMembers that has been declared and initialized,
3-an int variable memberID that has been initialized,
4-and an boolean variable isAMember,
write a code that assigns true to isAMember if the value of memberID can be found in currentMembers, and that assigns false to isAMember otherwise. Use only k, currentMembers, memberID, and isAMember.
Answer:
The program to this question as follows:
Program:
public class Main //define class main
{
public static void main(String[] args) //define main method
{
boolean isAMember = false; //define boolean variable isAMember
int currentMembers[]={1,72,36,43,51,61,72,80}; //declare and initialized array.
int memberID=72; //define integer variable memberID.
for(int k = 0; k < currentMembers.length; k++) //loop.
{
if(currentMembers[k] == memberID) //conditional statement.
{
isAMember = true; //assign value true.
break;
}
System.out.print("true"); //print value.
}
}
}
Output:
true
Explanation:
The above java program to this question can be described as:
In java program we define a class that is "Main" inside this class we define a main method in the main method we define variables that are "k, memberID, isAMember, currentMembers". The variable k and memberID is an integer variable that is used in the loop and use for match condition. and currentMembers is an integer array that is declared and initialized. and isAMember is a boolean variable that returns only true or false value.Then we define a (for) loop in this loop we check condition we use if block. In if block, we check that currentMembers array value is equal to memberID. if this condition is true so we assign value true in "isAMember" variable and print its value.5.Consider the following code snippet:ArrayList arrList = new ArrayList();for (int i = 0; i < arrList.size(); i++){ arrList.add(i + 3);}What value is stored in the element of the array list at index 0? Think carefully about this.A. 0B. 3C. 6D. None
Answer:
The answer to this question is the option "D".
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.That's why the correct answer to this question is the option "D".

Given the following method definitions: void mystery(double a) { System.out.print("double! "); } void mystery(int a) { System.out.print("int! "); } What will be the output of the following code? mystery(1); mystery(1.0); Select one:
a. It is impossible to predict
b. int! double!
c. Duplicate function names results in a compiler error.
d. double! int!
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.

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

Given the char * variables name1, name2, and name3, write a fragment of code that assigns the largest value to the variable max (assume all three have already been declared and have been assigned values).
Answer:
The following code as follows:
Code:
max=name1; //define variable max that holds name1 variable value.
if (strcmp(name2, max)>0) //if block.
{
max=name2; //assign value to max.
}
if (strcmp(name3,max)>0) //if block.
{
max=name3; //assign value to max.
}
Explanation:
In the above code, we define a variable that is max. The data type of max variable is the same as variables "name1, name2, and name3" that is "char". In the max variable, we assign the value of the name1 variable and use if block statement two times. In if block, we use strcmp() function that can be defined as:
In first if block we pass two variables in strcmp() function that is "name2 and max" that compare string value. If the name2 variable is greater then max variable value so, the max variable value is change by name2 variable that is "max=name2". In second if block we pass two variables in strcmp() function that is "name3 and max" that compare string value. If the name3 variable is greater then max variable value so, the max variable value is change by name3 variable that is "max=name3".

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.
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.

The following code accomplishes which of the tasks written below? Assume list is an int array that stores positive int values only.int foo = list[0];for (int j =1 ; j < list.length; j++) if (list[j] > foo) foo = list[j];
Answer:
The code mention in question will find "Largest Number in list"
Explanation:
In first line of code
first element of array will be move in "foo" variable
then loop will start from 2nd value and ends at last value of array
in next step
2nd value of array compares with 1st value
If 2nd value is greater than 1st then greater value move into "foo" variable.
This process continues till the end of array.
after completion largest element of array will be present in "foo".

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.
