编写程序计算斐波那契数列第n项

斐波那契数列至少会给出前2,3项,而从找找规律.这里我们比如是1,2,3,5；则：它的规律是：N1=1,N2=2;N3=N1+N2;N4=N2+N3;...Nn=N(n-2)+N(n-1);int[]

添加一个文本框输入前N项的N值,再添加一个命令按钮即可PrivateFunctionF(NAsLong)AsLongIfN>2ThenF=F(N-1)+F(N-2)ElseF=1EndIfEndFun

帮你写好了.unsigned int fib(unsigned int n) {\x09if (n == 1 

#includelongintfn(int);voidmain(){printf("%d",fn(10));}longintfn(intm){longinttemp;if((1==m)|(2==m))

(1/√5)*{[(1+√5)/2]^n-[(1-√5)/2]^n这个是斐波那契数列的通项公式,差分方程的z变换可求得要算前n项和就很简单了吧

第n个元素等于第n-1加n-2个元素调用递归实现啊

#includeintFibonacci(intn){if(n==1||n==2)//递归结束的条件,求前两项return1;elsereturnFibonacci(n-1)+Fibonacci(n-

PrivateSubForm_Load()Rem在这里定义一个inti来控制数字的循环变化,定义intNumber是用来输入要求第几个数Diminti,intNumberAsInteger'lngFi

sum=sum+1/(5*i+1);这一句,1/(5*i+1)的值是整数的,所以它一直是0这样好像可以sum=sum+(double)1/(5*i+1);

#include"stdafx.h"voidmain(){ints=0;for(intn=1;n

“i=1”---->"i==1","i=2"------>"i==2"

#includeintfibo(intn){if(nreturn1;elsereturnfibo(n-1)+fibo(n-2);}intmain(){intn;scanf("%d",&n);print

用什么语言呢?C还是PASCAL、VB?再问：vc++再答：#include<stdio.h>main(){ longa[30],i; a[0]=1;a[1]=1;&n
