Implement a public class called comparepets. comparepets should provide a single static method named equals that takes two pet references and returns an int. if the two pet references are equal you should return 1. else if the two pet instances are equal you should return -1. otherwise return 0. note that one or both of the pet references may be null, in which case you should return 0 unless both are null in which case you should return 1. java

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
