int main()
{
	cout << "Please enter a integer value\n";
	int n;

	cin >> n;
	cout << "n ==" << n
		<< "\nn + 1 ==" << n + 1
		<< "\nthree times n ==" << 3 * n
		<< "\ntwice n ==" << n + n
		<< "\nn squared ==" << n*n
		<< "\nhalf of n ==" << n / 2
		<< "\nsquare root of n ==" << sqrt(n)
		<< "\nremainder of n " << n % 2
		<< "\nmodulor of n and 2 ==" << n % 2
		<< "\nmodulor of n and 3 ==" << n % 3
		<< '\n';
	keep_window_open();
}
Output:
Please enter a integer value
5
n ==5
n + 1 ==6
three times n ==15
twice n ==10
n squared ==25
half of n ==2
square root of n ==2.23607
remainder of n 1
modulor of n and 2 ==1
modulor of n and 3 ==2
