+"""
+Also in Java, the operator % can be used to return the remainder of a division calculation. 
+
+For example, the operator works like this:
+int remainder = 5 % 2;
+// prints 1, because 5 / 2 == 2, remains 1.
+System.out.println(remainder);
+
+The same operator can be used to conveniently test whether a number is even: 
+if the remainder of the division by two is one, the number is odd.
+
+
+
+Write a program that asks the user for an integer and then prints the information whether the number is odd or even, as shown in the example output below. Thus, below is shown the execution of the program in duplicate:
+
+
+Example output 1:
+Give a number: 8
+Number 8 is even
+
+
+Example output 2:
+Give a number: 3
+Number 3 is odd
