A: To permanently remove a file from her computer, Sarah doubled-clicked on the My Computer icon and searched for her file under the “Uninstall or change a program” menu option.

or

b: empty the recycle bin : You can permanently delete a program file installed in the computer by following the procedure in option A. The option above will take you to the control panel and you'll be able to select the program you'd want to permanently remove. If you had initially deleted a file like a picture or a document or anything else that you necessarily do not need, it will go to recycle bin. You can head over there and select the Empty the Recycle Bin option to permanently delete the file.

4.14 LAB: Countdown until matching digits In C++ Write a program that takes in an integer in the range 20-98 as input. The outpu

Fantom [35]

Answer:

Here is the C++ program:

#include <iostream> // to use input output functions

using namespace std; // to identify objects like cin cout

int main() { //start of main function

int number; //an integer value

cout<<"Enter an integer: "; //prompts user to enter a number

cin >> number; // reads integer value from user

if (number > 98 || number < 20) { //if number is not between 20 and 98

cout<<"Input must be 20-98"; } //display this message if number is not between 20 and 98

else { // if number is in range 20-98

while(number%11){ // loop keeps taking mod of input number with 11 until matching digits found

cout<<number<<" "; //displays the numbers

number--; } // decrements the value of number by 1

cout<<number<<" "; } } // displays the matching digits

Explanation:

I will explain the program with an example:

Let suppose the number = 90

The if condition evaluate to false because 90 is in the range of 20-98 so the else part executes which has a while loop that works as following:

while(number % 11)

At first iteration:

This while(number % 11) is basically equivalent to :

while(number % 11 != 0)

while(90 % 11)

The % operator is the modulo operator which returns the remainder of the division. So when 90 is divided by 11 the remainder is 2. This is not equal to 0. So the statement under while condition executes:

cout<<number<<" "; This statement displays the number on output screen. Since number = 90 so 90 is printed. " " adds a space with the number

90

Next the value of number is decremented to 1 so number = 89

At second iteration:

while(number % 11) becomes:

while(89 % 11)

When 89 is divided by 11 the remainder is 1. This is not equal to 0. So the statement under while condition executes:

cout<<number<<" "; This statement displays the number on output screen. Since number = 89 so 89 is printed. " " adds a space with the number

90 89

Next the value of number is decremented to 1 so number = 88

At third iteration:

while(number % 11) becomes:

while(88 % 11)

When 89 is divided by 11 the remainder is 0. So the while loop breaks because the condition while(number % 11 != 0) evaluates to false. So the statement in while loop does not execute and program control moves to the following statement:

cout<<number<<" "; This statement displays that number whose digits match on the output screen with a space. So the output of the entire program is:

90 89 88

The program along with the output using example given in the question i.e. input is 93 is attached in a screenshot.
