A files counter (named filecnt) program filecnt accepts one argument which is the path of a directory in a Unix file system. The minimum requirement is that filecnt can accept and process an absolute path, but if your program can accept and process other forms of paths (e. g. relative path, '~' expansion, etc...) extra credit points will be given. If you implement these extra features they must be clearly documented to receive extra credit points.

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
