Answer the following questions:

victus00 [196]

Answer:

The answer to the following questions can be given as:

Question: 1

value of foo is = 1020

Question: 2

Output of the code is = false

Question: 3

function add(a, b)

{

return a && b ? a + b : function (c) { return a + c; };

}

var a=add(2,5);

var x=add(2)(5);

print(a);

print(x);

output:

7

Question: 4

"goh angasal a m'i"

Question: 5

In this we check that if in the window a foo function exists. otherwise we set windows.foo to bar.

Question: 6

first alert shows the value "Hello World";

second alert shows value ReferenceError, In this bar not defined.

Question: 7

The value of foo.length is 2

Question: 8

The value of foo.x is undefined

Question: 9

Function print = "one", "three", "two" .

Question :10

It is difficult to define because doSomethingElse() function is not defined.

Explanation:

In question 1 the value of the foo variable is 1020 because we perform the string concat operation.

In question 2 Output of the code is false because float value keeps in binary and when we convert 0.1 or 0.2 to binary so it is not the same.

In question 3 the output of both functions is 7.

In question 4 the output is goh angasal a m'i because In this code we use the reverse() function, split() function and join() function. Reverse function reverses the value. split function splits the value and join function join all the value of the string in a line.

In question 5 we check the value.

In question 6, the first output is Hello World and second is ReferenceError.

In question 7, the value of foo.length is 2 because this foo array we insert only 2 values.

In question 8, the value of foo.x is undefined because in the variable we reset the value of foo all together, so foo.x value is undefined.

In the question 9 function print "one",

"three",

"two" because In the function first, we print the message that is "one" then we define a function in this function we print the value

"two" but before creating object we call the "three" so the print value is "one",

"three",

"two".

In question 10 function, the output of this function is undefined.

Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre

Fudgin [204]

Answer:

The c++ program to implement the while loop is given below.

#include <iostream>

using namespace std;

int main() {

// declaration of integer variables

int k, n, total;

// initialization of integer variables

k=1, n=4, total=0;

// loop executed till value of k becomes equal to value of n

while( k <= n ){

// cube of every integer is added to the variable total

total = total + ( k * k * k );

// value of k is incremented to go to the next number

k = k + 1 ;

}

return 0;

}

Explanation:

The program begins with the declaration of integer variables.

int k, n, total;

This is followed by initialization of these variables.

k=1, n=4, total=0;

The while loop runs over the variable k which is initialized to 1. The loop runs till value of k reaches the value of integer n.

First, cube of k is computed and added to the variable total.

After first execution of the loop, total is initialized to the cube of 1.

Next, value of variable k is incremented by 1 so that k is initialized to next integer.

After first execution of the loop, k is incremented from 1 to 2.

while( k <= n )

{

total = total + ( k * k * k );

k = k + 1 ;

}

When the value of k reaches the value of integer n, the cube of n is calculated and added to the variable, total.

When k is incremented, it becomes more than n and hence, loop gets terminated.

As the return type of main is int, the program terminates with the statement shown below.

return 0;

No output is displayed as it is not mentioned in the question.

No user input is taken as it is mentioned that integer variables are already initialized.

Which of the following factors wouldn't change an account's optimization score?

MatroZZZ [7]

Answer:

Renaming Campaigns

Explanation:

Based on the information provided within the question it can be said that the factor that wouldn't change this would be Renaming Campaigns. This is because an account's optimization score is an estimate of how well the account/campaign will perform in the near future. Changing the name will not change this score since the campaign is still following the same strategy and therefore the estimates will be the same.
