How to find the factorial of a number using recursion in C ?
The Formula to find the factorial of a number (n) is
(n!) = 1*2*3*4….n
Here’s a C program to demonstrate this.
#include <stdio.h>
long int FindProduct(int n);
int main()
{
int input;
printf("Abundantcode.com Coding samples\n");
printf("Enter a Number : ");
scanf("%%d", &input);
printf("Factorial of %%d = %%ld", input, FindProduct(input));
return 0;
}
long int FindProduct(int input)
{
if (input >= 1)
return input*FindProduct(input-1);
else
return 1;
}
Output
