Create a program in C with a function \"factorial\" using the code given to you

Question

Create a program in C with a function "factorial" using the code given to you in the book for recursively creating a factorial sequence 6-25.

You need to write main program which will prompt the user for "n" and then call the factorial function by value. Your returned value should be printed out to the user.

me Calculate the factorial of There is no test that the result Pre n is the number to Post result is returned lal of a number using a loop- the result fits in a long. number to be raised factorially long factorial (int n) // Local Declarations long facts = 1; 10 Statements for (int i = 1; facts = facts * i; i

Explanation / Answer

Hello Student!

I am happy to help you!

Here goes the code :

#include <stdio.h>

// Recursive function for calculating factorial

long factorial(long int n) {

if (n == 1 || n == 0) {

return 1;

}else {

// Call recursively

return n*factorial(n-1);

}

}

int main(int argc, const char * argv[]) {

// Enter the value of n

printf("Enter the value of n :");

// Declaration of n

long int n;

// Taking input

scanf("%ld", &n);

// Printing factorial

printf("The factorial value is : %ld ", factorial(n));

return 0;

}

Test Case :

Enter the value of n :5

The factorial value is : 120

Program ended with exit code: 0
