C program to find the factorial of a given number.
In this tutorial we will learn how to write a c program to find the factorial of a given number.
If we will enter a number as 5 then the factorial of 5 is:-
5 * 4 * 3 * 2 * 1 = 120
The factorial of 5 is 120.
Example-
#include <stdio.h>
#include<conio.h>
long int fact(int n);
int main()
{
int n;
printf("Enter a positive integer: ");
scanf("%d", &n);
printf("\nFactorial of %d = %ld", n, fact(n));
return 0;
}
long int fact(int n)
{
if (n >= 1)
return n*fact(n-1);
else
return 1;
}
