#include < math.h >		// necessary for square root function



void main()

{

	// define variable for entry by user

	int number;



	// set real number output as fixed

	cout << setiosflags(ios::fixed);



	cout << "Enter a positive integer ... ";

	cin >> number;

	// display 0 decimals for square of integer

	cout << setprecision(0) << endl;

	cout << "The square of the number is " << pow(number,2) << "!" << endl << endl;

	// display 4 decimals for square root of integer

	cout << setprecision(4);

	cout << "The square root of the number is " << sqrt(number) << "!" << endl << endl;



	// Prompt user to hit enter to continue

	cout << "Hit enter to continue ... " << endl;
