In main() you will still prompt the user for a positive integer, n, but then you will pass it to a function that calculates n! and then returns the value to main() for printing.Code:#include <stdio.h> int main(void) { int n, i, sum; printf("Enter a value for n!: "); scanf("%d", &n); sum = n; for( i = 1; i < n; i++ ) sum = sum * ( n - i ); printf("n! is %d\n", sum); }
How do I change this into a function?

Have you looked at functions at all? In your book? In tutorials?
A little bit, why?
But what is a good tutorials site?
Why? Because you said you wanted to make some of your code into a function. So we check that you even know what a function is. You can look at this very site for some tutorials. Essentially whatever code calculates your value (in this case, n!) you put in a separate function to be called from whatever piece of code needs it.
