factorial 5 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
unsigned long long factorial(unsigned long long num){
if(num<=0)
return 1;
return num * factorial(num-1);
}
Example 3: Factorial
// METHOD ONE
const factorialNumber = num => {
let factorials = []
for(let i = 1; i <= num; i++) factorials.push(i)
return factorials.reduce((acc , curr) => acc * curr, 1)
}
// METHOD TWO
const factorialNumber = num => {
let factorial = 1, i = 1
while(i <= num){ factorial *= i; i++ }
return factorial
}
// METHOD THREE
function factorialNumber(num) {
if(num < 1) return 1
else return factorialNumber(num - 1) * num
}
Example 4: factorial of 8
function getFactorial($int)
{
$factorial = 1;
for ($i = $int; $i > 1; $i--)
{
$factorial *= $i;
}
echo "The factorial of " . $int . " is " . $factorial . '
';
}
Example 5: how to factorise
print ("bum hole")
