Answer:
// C++ program to find factorial of given number
#include <iostream>
using namespace std;
// function to find factorial of given number
unsigned int factorial(unsigned int n)
{
if (n == 0)
return 1;
return n * factorial(n - 1);
}
// Driver code
int main()
{
int num = 5;
cout << "Factorial of "
<< num << " is " << factorial(num) << endl;
return 0;
}
Answer:
# Factorial of a number using recursion
def recur_factorial(n):
if n == 1:
return n
else:
return n*recur_factorial(n-1)
num = 7
# check if the number is negative
if num < 0:
print("Sorry, factorial does not exist for negative numbers")
elif num == 0:
print("The factorial of 0 is 1")
else:
print("The factorial of", num, "is", recur_factorial(num))
hope help u mate ✌
