Answer:

fasten things, hold/pull things, amplify force

Explanation:

A screw is a type of simple machine.

It can be used to fasten 2 or more things together (ex planks of wood). It can also be used to pull something by screwing into the material and staying there (ex corkscrew for opening wine bottles). It can also be used to magnify force. You can tighten a wingnut by hand and get a significant amount of vertical holding power.

sertanlavr [38]

Answer:

#include <iostream>

using namespace std;

class Digits

{

   public:

   int num;

   int read()       //method to read num from user

   {

       cout<<"Enter number(>0)\n";

       cin>>num;

       return num;

   }

   int digit_count(int num)  //method to count number of digits of num

   {

       int count=0;

       while(num>0)    //loop till num>0

       {

           num/=10;

           count++;   //counter which counts number of digits

       }

       return count;

   }

   int countDigits(int num)   //method to return remainder

   {

       int c=digit_count(num); //calls method inside method

       return num%c;  

   }

};

int main()

{

   Digits d;    //object of class Digits is created

   int number=d.read();   //num is read from user

   cout<<"\nRemainder is : "<<d.countDigits(number);  //used to find remainder

   return 0;

}

Output :

Enter number(>0)

343

Remainder is : 1

Explanation:

As program is missing to find errors , a logically write program is written to find the remainder when a number is divided by its number of digits. A class  Digits is constructed which has public variable num and methods read(), digit_count(), countDigits().

  • read() - This method reads value of num from the user and return num.
  • digit_count() - This method takes a integer as parameter and counts the number of digits of a number passed as argument. while loop is used to increement the counter until num<0. This returns the value of count.
  • countDigits() - This method takes a integer as a parameter and returns remainder when the argument is divided by number of  digits of argument. Number of digits is calculated by using method digit_count().

At last in main method , object of Digits class is created and its methods are used to find the output.
