Question

Write a recursive function to calculate and return factorial of a given number 'n'. in C progrmaining

Answer 1

ANSWER:

Code with explanation:

// Function to find factorial of a number n :
int find_factorial(int n)
{
   //Factorial of 0 is 1
   if(n==0)
      return(1);

   //Function calling itself: recursion
   //Here we call the function recursively for a number less than the number in the previous recursive call
   return(n*find_factorial(n-1));
}



//The code below is to call the above Factorial function and pass a value entered by the user, to check the output
#include<stdio.h>
int main()
{
    int num;
    //Ask user for the input and store it in num
    printf("\nEnter any integer number:");
    scanf("%d",&num);
    //Calling the factorial function here
    int fact = find_factorial(num);
    //Printing the factorial
    printf("\nfactorial of %d is: %d",num, fact);
}

Code: (Screenshot of executed code)

Code output:

Final clean function to copy:

// Function to find factorial of a number n :
int find_factorial(int n)
{
   //Factorial of 0 is 1
   if(n==0)
      return(1);

   //Function calling itself: recursion
   return(n*find_factorial(n-1));
}
