Write a class called Counter that represents a simple tally counter, which might be used to count people as they enter a room. T

he Counter class should contain a single integer as instance data, representing the count. Write a constructor to initialize the count to zero. Write a method called click that increments the count and another method called get Count that returns the current count. Include a method called reset that resets the counter to zero. Finally, create a driver class called CounterTest that creates two Counter objects and tests their methods.

Answer:

Code is in java

Explanation:

Code is self explanatory, added come comments to explain more about the code.

public class CounterDriver {

   public static void main(String[] args){

       // Creating counter first object

       Counter counter1 = new Counter();

       //performing 2 clicks

       counter1.click();

       counter1.click();

       // displaying counter 1 click count

       System.out.println("Total Number of counter1 clicks :"+counter1.getCount());

       // resetting counter 1 click count

       counter1.reset();

       // again displaying click count which will be 0 after reset

       System.out.println("Total Number of counter1 clicks :"+counter1.getCount());

      // Same operation goes with counter 2  

       // the only difference is that it performs 3 clicks

       Counter counter2 = new Counter();

       counter2.click();

       counter2.click();

       counter2.click();

       System.out.println("Total Number of counter2 clicks :"+counter2.getCount());

       counter2.reset();

       System.out.println("Total Number of counter2 clicks :"+counter2.getCount());

   }

}

class Counter{

   int count;

// defining constructor which will initialize count variable to 0

   public Counter(){

       this.count=0;

   }

// adding click method to increment count whenever it's called

   public void click(){

       this.count++;

   }

// getCount method will return total count

   public int getCount(){

       return this.count;

   }

// reset method will set count to 0

   public void reset(){

       this.count = 0;

   }

}

int quarters = coins/25;

 

coins = coins%25;

 

int dimes = coins/10;

 

coins = coins%10;

 

int nickles = coins/5;

coins = coins%5;

 

int pennies = coins/1;

 

if(((a*25) + (b*10) + (c*5) + (d*1))==temp)

cout<<"\tQuarters: "<<quarters<<endl;

cout<<"\tDimes: "<<dimes<<endl;

cout<<"\tNickles: "<<nickles<<endl;

cout<<"\tPennies: "<<pennies<<endl;

return 0;

}#include <iostream>

#include <stdlib.h>

using namespace std;

int main()

{

srand(time(0));

 

int coins = rand()%99 + 1;

int temp = coins;

int quarters = coins/25;

 

coins = coins%25;

 

int dimes = coins/10;

 

coins = coins%10;

 

int nickles = coins/5;

coins = coins%5;

 

int pennies = coins/1;

 

if(((a*25) + (b*10) + (c*5) + (d*1))==temp)

{

cout<<"That's correct"<<endl;

 

if(a!=quarters || b!=dimes || c!=nickles || d!=pennies)

}

 

cout<<"\tQuarters: "<<quarters<<endl;

cout<<"\tDimes: "<<dimes<<endl;

cout<<"\tNickles: "<<nickles<<endl;

cout<<"\tPennies: "<<pennies<<endl;

return 0;

}

Explanation:

  • Use the built-in rand function to generate a random coin.
  • Get all the required values for quarters, dimes, nickles and pennies and store them in variables.
  • Check if the coins give a value of temp, then answer is correct and the values of user will be added.
  • Optimum solution is displayed  If it does not matches with the optimum solution. Display that the answer is wrong along with solution.

How does a paper prototype minimize constraints when compared to a digital one
aksik [14]

A regular prototype minimizes constraints if compared to a paper one because possible problems in use can be identified easily.

<h3>What is a prototype?</h3>

This refers to the initial model of a product designed to test the features of the model before it is released to the market.

<h3>What are the differences between digital and paper prototypes?</h3>

Online protoypes are often time-saving, however, because some features of the prototype cannot be tested, a regular protoype is much better to identify possible problems in design or use.

What is different between a pc mouse and a real mouse
love history [14]

Answer:

These two things are in no way similar.

First of all, a real mouse is a rodent. Which means that it is a living, breathing, mammal.

A PC mouse is an accessory to a computer. It is not living and will never be alive.

Please do not put a pc mouse in a cage and try to feed it.
