Write this in C. please make it clear and post a screenshot or in a good outline .
8.03) Write a function fact_calc that takes a string output argument and an integer input argument
n and returns a string showing the calculation of n !. For example, if the value supplied for n were
6, the string returned would be 6 ! 5635343332315720 Write a program that repeatedly prompts
the user for an integer between 0 and 9, calls fact_calc and outputs the resulting string. If the user
inputs an invalid value, the program should display an error message and re-prompt for valid input.
Input of the sentinel -1 should cause the input loop to exit. Note: Don't print factorial of -1 , or any
number that is not between 0 and 9. SAMPLE RUN #4: . /Fact.
