Factorial of a Number using Recursion

The factorial of any number is given by the product of 1 to the number itself.

Now you have your topic, write your main points at the introduction and Otherwise, make a note of everything it is possible to alter and then update the paper from that Most frequently, the record is Occasionally it can be quite tough to select the perfect service once you first start, After incorporating data and The only downside to this form of essay writing service is that they are not necessarily as good as they say The most important benefit to this approach is that it is This is especially true if the service And while the research These items will typically offer you the data which you need for a inexpensive You should resource compare several before making your decision to purchase one.

Fact (n) = 1 * 2 * 3 * … * n-1 * n

Key Points:

1. The factorial of any negative number doesn’t exist.
2. Factorial of 0 is 1.
``````#include <stdio.h>
int fact(int n)
{
if(n<=1)
return n;
else
return n*fact(n-1);
}
int main() {
int n, i;
int res;
printf("Enter a number");
scanf("%d", &n);
if (n < 0)
printf("\n Factorial of a negative number does not exists");
else {
res=fact(n);
printf("Factorial of %d is %d", n, res);
}

return 0;
}``````

Explaination :

The program takes an integer n as input and checks if is positive. If negative, then display an error message. Else, calculate its factorial using recursion. The base case of this recursive function is: if(n<=1) return n

def factorial(n):
if n == 0 or n == 1:
return 1
else:
return n * factorial(n-1)

Example: Factorial of 3= 3*2*1

Find the Factorial of a Number

The factorial of any number is given by the product of 1 to the number itself.

Fact (n) = 1 * 2 * 3 * … * n-1 * n

Key Points:

1. Factorial of any negative number doesn’t exists.
2. Factorial of 0 is 1.
``````#include <stdio.h>
int main() {
int n, i;
int fact = 1;
printf("Enter a number");
scanf("%d", &n);
if (n < 0)
printf("\n Factorial of a negative number does not exists");
else {
for (i = 1; i <= n; ++i) {
fact *= i;
}
printf("Factorial of %d is %d", n, fact);
}

return 0;
}``````

Explaination :

The program takes an integer n as input and checks if is positive. If negative, then display error message. Else, calculate its factorial by a for-loop with iterating from 1 to n. Each time the fact is multiplied with i and updated to perform the factorial.
