# Project 9

**for loop (75 points)**

- Your program must allow the user to input an unsigned integer at the
keyboard and determine and output the factorial of the unsigned integer.
- Use a compound if statement to determine the factorial.
If the unsigned integer is zero or one then the factorial result is one.
Otherwise run through a for loop to output the factors and to determine
the factorial.
- Make sure your program can display the sample outputs below.
- Your code must be well documented. Also include your name, date,
project number and a breif description of the program.

**Sample output1**
Find the factorial of what number? : **4**
4! = 1 x 2 x 3 x 4 = 24
**Sample output2**
Find the factorial of what number? : **5**
5! = 1 x 2 x 3 x 4 x 5 = 120
**Sample output3**
Find the factorial of what number? : **0**
0! = 1
**Sample output4**
Find the factorial of what number? : **1**
1! = 1
