Talk C Chestnut Bar (third time: C language Instance--factorial)

Crossing, everyone, from today onwards, we talk about the large-scale couplet science fiction: C Chestnut, that is, C language examples. Gossip Hugh,

Words return to the positive turn. Let's talk about C language examples together!

Crossing, the last time we were talking about the example of a leap year, this time we say the example is: Seek factorial.

Crossing, factorial is an operation in mathematics that usually uses an exclamation point to represent a factorial. For example: 3! Represents the factorial of 3. The definition of factorial is this

N=0: When the phase of n is multiplied by 1,n>0, the factorial of n is nth (n-1).

Crossing, I've used two methods in my program to find factorial. One is a recursive method, the other is a cyclic method. It is not written in the text

Code out, detailed codes in my resources, you can click on the link to download the use.

One thing to add: loops and recursion are common methods, so there's not much to explain here. However, in the project to minimize the use of recursion, a

As a matter of case, recursion can solve the problem and can be solved using the cyclic method. The reason for not recommending recursion is that the performance of recursion is slightly

, especially if the nesting of recursion is relatively deep.

You crossing, we're going to talk about the factorial case. I want to know what the following example, and listen to tell.
