C language custom function, 1 to 10 factorial, how to write ah

#include "stdio.h"
int jiecheng(int n)
{
if(n==1)
return 1;
else return n*jiecheng(n-1);
}
int main()
{
Printf ("factorial of 10 is% d", Jiecheng (10));
return 0;

Input two positive integers m, N, write the factorial function, calculate m! / (n! * (m-n)!). C language function solution, thank you

#include
long factorial(int m,int n){
long sum=1,sum1=1;
int i;
if(m-n>n){
for(i=m;i>m-n;i--)sum*=i;
for(i=2;in;i--)sum*=i;
for(i=2;i

Write a program to input positive integer n and calculate its factorial n! (n = n × (n-1) ×... × 3 × 2 × 1)

vb：
func fn(n as integer)
dim m=1
for i=1 to n
m=m*i
next
return m
end func
c/java：
function fn(int n){
int m=1;
for (int i=1;i

Senior high school compulsory three problem writing program, input positive integer n, calculate its factorial n! (n! = n * (n-1) *. * 3 * 2 * 1) We also write a program to calculate the sum of the following n (n belongs to n) numbers: It is said in books that he is a basic programming language With compulsory three mathematics book procedures from time to time do not understand

Factorial of N:
dim n as single,i as single,s as single
N = InputBox ("please input integer n:")
S=1
for i=1 to n
s=s*i
next i
print "s=";s
Calculate the sum of the following n (n belongs to n): 2,3 / 2,4 / 3,5 / 4,..., N + 1 / n
dim n as integer,i as integer ,s as single
S=0
n=inputbox("Please input number:")
for i=1 to n
s=s+(i+1)/i
next i
print "s=";s

Write a program, input positive integer n, calculate its factorial n!

#include
int main(void)
{
int i,s=1;
printf("Please input a intdata:");
scanf("%d",&i);
for(;i>1;i--)
s*=i;
printf("%d\n",s);
return 0;
}

Write a program, input positive integer n, calculate its factorial n! (n! = n * (n-1) *) *3*2*1)

I don't know what language you're using. I only give a JavaScript and a factorial function written in C language
Writing in other languages should also be interlinked. Slowly understand it
Written in javascript:
Written in C language:

Sum n \ (n + 1)! Note that the denominator is a factorial of N + 1

From K / (K + 1)! = (K + 1-1) / (K + 1)! = 1 / K! - 1 / (K + 1)!,
So 1 / 2! + 2 / 3! + 3 / 4! + +n/(n+1)!
=1/1!-1/2!+1/2!-1/3!+1/3!-1/4!+… +1/n!-1/(n+1)!
=1-1/(n+1)!

VB do cycle 1. N factorial n! 2.2-100 all even 3. The sum and product of the first 10 natural numbers

1. Dim n As Integer, i As Integer Dim ji As Double n = Val(Text1.Text) i = 1 ji = 1 Do ji = ji * i i = i + 1 If i > n Then Exit Do Loop Print ji2. Dim i...

Find VB question code: find any number of factorial cumulative sum. S = 1! + 2! + 3! +... + n!, n is input by the user

The first floor is very complicated. Here is a simple one: private sub commandbutton1_ Click() dim I, s, kdim NaAA: n = InputBox ("please input a number greater than or equal to 1") if val (n) > = 1 then if len (n) = 0 then end for I = 1 to n s = S + I * i n

Why is the limit of (factorial of n) divided by (the x power of E) (x tends to be positive infinity) infinitesimal (factorial of n) is a molecule, (e to the x power) is the denominator X - > positive infinity N belongs to the integer Z

When x tends to be positive infinity, the power of e tends to be positive infinity, and the factorial of n is a constant
So the limit is infinitesimal
