If the two cylinders are in the fully retracted position, depressing a START pushbutton will cause the feed cylinder rod to extend.
When the feed cylinder rod becomes fully extended, the press cylinder
rod starts to extend. A pressure switch detects the pressure in the cap
end of the press cylinder.
When this pressure attains 600 kPa
(or 80 psi), a timer is started. This timer is used to delay the retraction
of the press cylinder rod for a period of 3 s.
After the delay, both cylinder rods retract.
When the cylinder rods become fully retracted, they stop and wait for
the operator to start another cycle.

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
