Explanation:

To understand how this program is working let us print the variable value at different stages of the program so that we can understand how it is working.

Intitally, value=10 when it was declared.

Then we added 5 and it become value=15

then we used fork() function which creates a parent(orignal) and child(duplicate)

When fork() succeeds it returns the child pid to parent and returns 0 to the child. As you can see (pid > 0) condition is always true therefore the parent pid value becomes 35 ( 15+20) and the child pid value becomes 0.

#include <stdio.h>

#include <unistd.h>

int main( ) {

   int value = 10;

     printf("%d\n",value);

   int pid;

   value += 5;

     printf("%d\n",value);

   pid = fork( );

     printf("%d\n",pid);

   if (pid > 0 )

   {

       value += 20;

   }

   printf("%d\n",value);

   return 0;

}

Output:

10 (initial value)

15 (modified value)

5343 (pid when fork is used)

35 (final modified value)

0 (child value)

15 (the parent value when fork was used)

USPshnik [31]

The code below is written in javascript which gives us the integer,

<h3>The function code is</h3>

function solution (num){


//Javascript function


var x=0,sum=0,a,b;


var d=""; //variable declaration


var digits = num.toString().split('');


var Individual = digits.map(Number);


//console.log(Individual);


for (var i=0;i<Individual.length;i++)


{//For loop


x=x+Individual[i];


}


var y=x*2;


for(var i=0;i<Individual.length;i++)


{


sum=sum+Individual[i];


d=""+d+Individual[i];


if(sum==y)


break;


if(i==Individual.length-1)


{


i=-1;


continue;


}


}


console.log("the value is "+d);


}


var number = prompt("enter the number");


//Asking user for value...


console.log("the number is");


console.log(number);

Write a function listLengthOfAllWords which takes in an array of words (strings), and returns an array of numbers representing t
vesna_86 [32]

Answer:

   public static int[] listLengthOfAllWords(String [] wordArray){

       int[] intArray = new int[wordArray.length];

       for (int i=0; i<intArray.length; i++){

           int lenOfWord = wordArray[i].length();

           intArray[i]=lenOfWord;

       }

       return intArray;

   }

Explanation:

  1. Declare the method to return an array of ints and accept an array of string as a parameter
  2. within the method declare an array of integers with same length as the string array received as a parameter.
  3. Iterate using for loop over the array of string and extract the length of each word using this statement  int lenOfWord = wordArray[i].length();
  4. Assign the length of each word in the String array to the new Integer array with this statement intArray[i]=lenOfWord;
  5. Return the Integer Array

A Complete Java program with a call to the method is given below

<em>import java.util.Arrays;</em>

<em>import java.util.Scanner;</em>

<em>public class ANot {</em>

<em>    public static void main(String[] args) {</em>

<em>       String []wordArray = {"John", "James", "David", "Peter", "Davidson"};</em>

<em>        System.out.println(Arrays.toString(listLengthOfAllWords(wordArray)));</em>

<em>        }</em>

<em>    public static int[] listLengthOfAllWords(String [] wordArray){</em>

<em>        int[] intArray = new int[wordArray.length];</em>

<em>        for (int i=0; i<wordArray.length; i++){</em>

<em>            int lenOfWord = wordArray[i].length();</em>

<em>            intArray[i]=lenOfWord;</em>

<em>        }</em>

<em>        return intArray;</em>

<em>    }</em>

<em>}</em>

This program gives the following array as output: [4, 5, 5, 5, 8]

statuscvo [17]

Answer:

D. 25x24x23x22x21.....3x2x1.

Explanation:

The ceasar cipher is a encryption technique, that uses a combination of information or keys to encrypt an information.

The 25 shift ceasar cipher has 25 different combinations, so the number of probable random cipher substitution is 25!,

That is = 25 × 24×23× 22×..... ×2×1.
