Explanation:

Begin class Books:

   string title

   num pages

   num price

   num MIN_PAGES=200

   num HIGH_PRICE=0.10

   num LOW_PRICE=0.8      Books(title, page)

       title= title

        pages=page

        price=0.0

   end of constructor

string getTitle()

       return title

   end of getTitle

   num getPages()

       return pages

   end of getPages

   num getPrice()

       if(pages<=MIN_PAGES)

            price=getPages()*HIGH_PRICE

        else

            price=MIN_PAGES*HIGH_PRICE+(pages-MIN_PAGES)*LOW_PRICE

        end of if

        return price

   end of getPrice

  string toString()

       string s=""

        s+="Title: "+getTitle()

        s+="\nPages: "+getPages()

        s+="\nPrice: "+getPrice()

        return s

   end of toString

end Books class

explanation:

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
