24 Factorial Code Example

Example 1: calculate factorial

int factorial(int n) { 	int res = 1, i;      for (i = 2; i <= n; i++)          res *= i;      return res;  }

Example 2: factorial of 8

function getFactorial($int) {         $factorial = 1;     for ($i = $int; $i > 1; $i--)     {         $factorial *= $i;     }     echo "The factorial of " . $int . " is " . $factorial . '<br>'; }
