Question

Hello...Its not correct....

Please write a program which asks the user to type in an integer number. If the user
types in a number equal to or below 0, the execution ends. Otherwise the program
prints out the factorial of the number.
The factorial of a number involves multiplying the number by all the positive integers
smaller than itself. In other words, it is the product of all positive integers less than or
equal to the number. For example, the factorial of 5 is 1 * 2 * 3 * 4 * 5 = 120.
Some examples of expected behaviour:
Please type in a number: 3
The factorial of the number 3 is 6
Please type in a number: 4
The factorial of the number 4 is 24
Please type in a number: -1
Thanks and bye!
Please type in a number: 1
The factorial of the number 1 is 1
Please type in a number: 0.
Thanks and bye!
