Program:

#include <iostream> //defining header file

using namespace std;

int main() //defining main method

{

int n; //defining integer variables

cout<<"Enter number: "; //message

cin>>n; //input value by user

while (n< 100) //loop for check condition

{

cout<<n<<" ";//print value

n=n*2; //calculate value

}

return 0;

}

Output:

Enter number: 8

8 16 32 64

Explanation:

In the above C++ language code, a header file is included, then defining the main method, inside the method an integer variable n is defined, which is used for user input for calculating their double number.

In the next step, The while loop is declared, and the loop variable n range is defined, that its value is less than 100, inside the loop the variable n is used to calculate, its double number, and print function "cout" to print its value.

stepladder [879]

Answer:

Explanation:

The following code is written in Python. It is a recursive function that tests the first and last character of the word and keeps checking to see if each change would create the palindrome. Finally, printing out the minimum number needed to create the palindrome.

import sys

def numOfSwitches(word, start, end):

if (start > end):

return sys.maxsize

if (start == end):

return 0

if (start == end - 1):

if (word[start] == word[end]):

return 0

else:

return 1

if (word[start] == word[end]):

return numOfSwitches(word, start + 1, end - 1)

else:

return (min(numOfSwitches(word, start, end - 1),

numOfSwitches(word, start + 1, end)) + 1)

word = input("Enter a Word: ")

start = 0

end = len(word)-1

print("Number of switches required for palindrome: " + str(numOfSwitches(word, start, end)))

Students working at individual PCs in a computer laboratory send their files to be printed by a server that spools the files on

Vanyuwa [196]

Answer:

Explanation:

Disk space is a limited resource on the spooling partition and once it is filled the will cause a deadlock. Every single block that comes into the spooling partition claims a resource, and the one behind that wants resources as well, and so on. Since the spooling space is limited and half of the jobs arrive and fill up space then no more blocks can be stored, causing a deadlock. This can be prevented allowing one job to finish and releasing the space for the next job.
