Answer:

B) 120

Explanation:

In the first three lines of the code, three variables ans, x and y have been declared and initialized;

=> ans = 10;

=> x = 65;

=> y = 55;

On the fourth line and fifth line of the code, there is an if block statement that will get executed if the value of x is greater than or equal to that of y;

i.e

if (x >= y)

ans = x + y;

And since x = 65 and y = 55, it implies that x is greater than or equal to y.

Therefore the fifth line of the code will be executed

=> ans = x + y

=> ans = 65 + 55

=> ans = 120

Note:

Though the value of variable ans was initially 10 before the execution of the if statement, its new value 120 will replace the former value.

Therefore the value of ans after the code has been executed is 120

Answer:

Option B 120

Explanation:

There are three variables, ans, x and y given in the code. In beginning, the variable. ans, holds value of 10. And variable x and y hold value of 65 and 55, respectively. Since the value held by x is bigger than one held by y, the if condition is met and the statement ans = x + y will run. The execution of this statement will total x with y -> 65 + 55 and the initial value of ans is overwritten by the addition result which is 120.

Ray Of Light [21]

Answer:

Answered below.

Explanation:

This answer is applicable to Linux.

There are several commands for copying files in Linux. cp and rsync are the most widely used. cp though, is the command used to copy files and their contents.

To copy a file named report1.txt to another file named report1uc.txt in the current directory, the following command is run.

$ cp report1.txt report1uc.txt

You can change the case of the strings in the file by using the tr command.

tr [:lower:] [:upper:]

For example,

$ echo brainly | tr [:lower:]. [:upper:]

Write a complete Java program called Rooter that gets a positive integer called "start" from the user at the command line and th

Nataly_w [17]

Answer:

The program in Java is as follows:

import java.util.*;

import java.lang.Math;

public class Rooter{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int start;

System.out.print("Start: ");

start = input.nextInt();

while(start<=0){

System.out.print("Number must be positive\nStart: ");

start = input.nextInt(); }

while(start>=0){

System.out.println(Math.sqrt(start));

start--; }

}

Explanation:

This declares start as integer

int start;

This prompts the user for input

System.out.print("Start: ");

This gets input for start

start = input.nextInt();

The following is repeated until the user input is valid i.e. positive

while(start<=0){

System.out.print("Number must be positive\nStart: ");

start = input.nextInt(); }

The following while loop prints the square root of each number till 0

while(start>=0){

System.out.println(Math.sqrt(start));

start--; }

Answer:

Following is the expression written in "Bash script" (mixture of commands):

^\d{5}(?:[-\s]\d{4})?$

Explanation:

^ = For staring string (denotation).
\d{5} = Matching 5 digits (first five unknown x's)
(?:…) = Making Group (making group of former 5 digits)
[-\s] = Match a hyphen or a space

(checking if a hyphen is present?)

\d{4} = Matching 4 digits (next four unknown x's)
…? = Pattern before it is optional
$ = Ending of the string.(denotation)
