Answer:

Inkjet printers.

Explanation:

A printer is an output device in a computer network system, that takes electronic input and produces a hard copy of it. There are various types of printers. They are;

- 3d printers

- Laser printers

- plotters

- Inkjet printers

- Led printers

- Dot matrix printers

- All in one printers etc.

Just like most printers, the inkjet uses ink to create hard copies and unlike other printers, The inkjet makes uses of liquid ink, passing through a nozzle to make hardcopies of documents. This is a disadvantage because if the printer is not used for a long time, the ink dries up in the nozzle.

Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm:
love history [14]

Answer:

Explanation:

The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.

import math

def amountOfCoins(change):

   print("Change: " + str(change))

   quarters = math.floor(change / 0.25)

   change = change % 0.25

   dimes = math.floor(change / 0.20)

   change = change % 0.20

   pennies = math.floor(change / 0.01)

   print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))

You have to write a program that will read a number followed by a series of bit operations from a file and perform the given ope
tatuchka [14]

The program what will read a number followed by a series of bit operations from file and perform the given operations sequentially on the number is given below.

<h3>What is an operation in computer science?</h3>

An operation, in mathematics and computer programming, is an action that is carried out to accomplish a given task.

There are five basic types of computer operations:

  • Inputting,
  • processing,
  • outputting,
  • storing, and
  • controlling.

<h3>What is the requested program above?</h3>

#include <stdio.h>

#include <fcntl.h>

int main(int argc, char *argv[])

{

  int number, n, v, temp;

  char line[25], fun[10];

  FILE *f = fopen(argv[1], "r");

 

  fgets(line, 24, f);

  sscanf(line, "%d", &number);   //reading the number

  while( fgets(line, 24, f) )

   {

      sscanf(line, "%s %d %d", fun, &n, &v); //reading the commands

      switch(fun[0])           //checking which command to run

      {

          case 'g':    temp = 1;

                      temp = temp<<n;   //shifting for getting that bit

                      printf("%d\n",(number&temp)&&1);

                      break;

          case 's':   temp = 1;

                      temp = temp<<n;   //shifting for setting that bit

                      if(!v)

                      {

                          temp = ~temp;

                          number = number & temp;

                      }

                      else

                      {

                          number = number | temp;

                      }

                      printf("%d\n",number);

                      break;

          case 'c':   temp = 1;

                      temp = temp<<n;   //shifting for complimenting that bit

                      number = number ^ temp;   //xor to complement that bit

                      printf("%d\n",number);

                      break;

          default:printf("not defined");

      }

  }

  return 0;

}

Execution and Output:

terminal-> $ gcc -o first first.c

terminal-> $ ./first file1.txt
