use language c $($Use a while loop for this problem$)$ Write a function that computes the factorial of an integer. The

two function parameters are the non$-$negative integer whose factorial is to be calculated, and a pointer indicating

the location to which the result should the written. The function should return $0$ in case of successful execution or

return $-1$ in case of malformed$/$bad input.

Part B: Repeat Part A$,$ except this time use a for loop.
