#WSQ09 Factorial Calculator.

logo-factorial

Hello again people!, this post is about my new program “Factorial Calculator”, and as the name says, it calculates the factorial of the number that you choose. But what is a factorial?

The factorial function (symbol: !) means to multiply a series of descending natural numbers. Examples:

  • 4! = 4 × 3 × 2 × 1 = 24
  • 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040
  • 1! = 1

(Information taken from  https://www.mathsisfun.com/numbers/factorial.html).

Here is the code of the program:

As you can see, here we have to use the for loop, and that’s new for me, so we have some problems with it, but finally I learned how to use it and it’s so easy.

The for loop has the next sequence.

for ( the variable that are you going to use as a counter; the condition; and finally the variable with ++ to add 1 when the cycle is repeating)

{

The proccess of the loop

}

It seems like that.

for (int m=1; m<=num1; m++)
{
result=m*result;
}

 

So it was the new thing that i learned with this program, the for loop.

Now, check my program running:

If you have problems with it, you can see this information:

and if you dont understand clearly, dont feel affraid and ask me!

 

Here my code on GitHub, hope it will be useful for you!.
