Thread: Splitting up my Gosper's Algorithm into multiple Functions

Code:

// Required Libraries


#include <stdio.h>
#include <stdlib.h>
#include <math.h>


// Program Defined Specifics


#define PROGRAMMER_NAME "Leigh McKenzie"
#define PI 3.14159
#define E 2.7182818284;


// Start Program


int main(void)
{


        double n; // User defines this variable
        double sqrt_partial; // Gosper's formula under the square root, leaves out PI
        double sqrt_solved; // sqrt_part square rooted
        double n_factorial; // powers multipled by the solved square root


        printf("ESTIMATE A FACTORIAL NUMBER\n");
        printf("This program was written by %s.\n", PROGRAMMER_NAME);


        printf("Please enter a positive integer: ");
        scanf("%lf", &n);


        sqrt_partial = (2.0 * n) + (1.0 + 3.0);


        sqrt_solved = sqrt(sqrt_partial * PI);


        n_factorial = pow(n,n) * exp * sqrt_solved;
        printf("%.0f! equals approximately %.5f \n", n, n_factorial);

return EXIT_SUCCESS;
}

I need a function dedicated for the square root part of my problem. How do I split it up properly?

Thanks in advance for the help! this is only my second program

Does that even compile? You're multiplying by exp which is a function pointer. At best that would produce a garbage result.
You will want to actually call that function instead.
