Java - Factorial
I am printing the factorial of the first 10 numbers, so it is 0 - 9. The below code works for me. But I am unable to make the loop such that the factorial of 0 is within the loop too. Any advice is appreciated. Thank you.
public class fact {
public static void main(String[] args) {
System.out.println("\n\n(f) Loop to print first 10 factorial numbers");
System.out.println("\nFactorial of 0 is 1");
int fact = 1;
int index = 1;
while (index < 10)
{
fact*=index;
System.out.println("Factorial of " + index + " is " + fact);
index++;
}
}
}

How about adding an if condition in your while loop for index 0
int fact = 1;
int index = 0;
while (index < 10)
{
if(index == 0)
System.out.println("\nFactorial of 0 is 1");
else {
fact*=index;
System.out.println("Factorial of " + index + " is " + fact);
}
index++;
}
