Anton [14]2 years ago

Answer:

Explanation:

The best thing to do in this scenario would be to save all of the work that the user has just finished on a personal data USB drive and then delete any of his work off of the computer. Also, if the user entered into the computer using their own account they should also log off from the computer. The next individual can log in with their own account if they need to use the computer. This would make sure that their work is safe and with them, as well as making sure that no other individual can see, take, or modify the work that they have done.

Use the modulo operator (%) to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which
uranmaximum [27]

Hi, you haven't provided the programing language in which you need the code, I'll just explain how to do it using Python, and you can apply a similar method for any programming language.

Answer:

def rightMost(num):

   lenNum = len(str(num))

   rightNum = num%(10**(lenNum-1))

   print(rightNum)

   return(rightNum)

Explanation:

In this function we receive an integer number, then we find how many digits this number has, and finally, we find the rightmost digits; the main operation is modulo (takes the remainder after a division), what we want is to take all the digits except the first one, for that reason we find the modulo of the number when divided by ten to the power of the length of the number minus one, for example, if the number is 2734 we divided by 10^(4-1), where four is the length of the number, this way we get 2734/1000 and the module of it is 734.

Write a loop that reads c-strings from standard input where the c-string is either "land", "air", or "water". The loop terminate
Anvisha [2.4K]

Answer:

I am writing a C++ code.        

#include <iostream> // for input output functions

using namespace std; // identifies objects like cin cout

int main() { //start of main() function body

string c_string; // stores the string entered by user from land water or air

int land=0; // contains the number of times land string is read in

int air=0; //contains the number of times air string is read in

int water = 0; //contains the number of times water string is read in

cin>>c_string; //reads the string entered by user from air water or land

/*while loop continues to execute until user enters xxxxx or maximum length of a string exceeds 8 */

while(c_string!= "xxxxx" && c_string.length()<=8) {

if(c_string=="land"){ // if string entered by user is land

land = land + 1;} //counts and increments each occurrence of land string by 1

else if(c_string=="air"){// if string entered by user is air

air = air + 1;}// counts and increments each occurrence of string air by 1

else if(c_string=="water"){// if string entered by user is water

water = water + 1;}//counts and increments each occurrence of air by 1

cin>>c_string;}

/* keeps reading the string entered by user from land air or water, until the loop breaks after the user enters xxxxx or user enters a string whose length is greater than 8 */

//prints the number of times land, air and water are read in

cout << "land:"<<land;

cout << endl<<"air:"<<air;

cout << endl<< "water:"<<water; }                      

                                                                                     

Explanation:

Everything is well explained in the comments above.

The program prompts the user to input strings. These strings are either land air or water. The while loop continues to read the input strings until user enters xxxxx or the string entered by user exceeds the length 8. Both these terminating conditions are added in the while loop. After the loop terminates, the number of times land, air and water strings are read is displayed on the output screen. Any other string entered by user other than these 3 is ignored. The program along with the output is attached.

Which things computer case contains
Ronch [10]

Inside the case are the components that make up the computer itself, such as the RAM memories, the processor and the hard disk, all of which are directly or indirectly connected to the motherboard. In addition, the case allocates the power suplly, which is responsible for supplying power to the computer.

<h3>What is a computer case?</h3>

The case is the hardware component used to house most parts of a computer. It is inside it that components such as CPU, motherboard, SSD, video card and power supply are placed.

In addition, it is where the outputs for connections to other equipment are found, such as USB and HDMI outputs, plug for sound box and microphone and input for memory card.

The case has the important function of protecting the internal components of a computer from knocks, heat, light, moisture and dust. That's because most of the electronic components inside a computer are very sensitive and need this protection.

It is also used to connect to other hardware components, such as a monitor, keyboard, mouse and headset, through the various outputs provided on its exterior.
