Using the computer language C

On paper (no computer needed), do the following programming (write the code by hand as you would on a test or an exam). 4. For any integer n > 0, ! is defined as the product i Xn-IXN-2... X2 Xl. 0! is defined to be I. It is sometimes useful to have a closed-form definition instead: for this purpose, an approximation can be used. R.W. Gosper proposed the following such approximation formula: Create a program that prompts the user to enter an integer nuses Gosper's formula to approximaten!, and then displays the result. The message display- ing the result should look something like this: 5! equals approximately 119.97003
