用vb do loop编写斐波那契数列前20项的和

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

为用了很没有效率的递归,所以出结果有点慢#includeiostream.h
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))
PrivateFunctionF(nAsLong)AsLongIfn>2ThenF=F(n-1)+F(n-2)ElseF=1EndIfEndFunctionPrivateSubCommand1_Cli
#includelongintf(intn){if(n==0)return0;elseif(n==1)return1;elsereturnf(n-1)+f(n-2);}intmain
// C++int F(int n) {if (n == 0) return 1;else if
staticvoidMain(string[]args){doublei=1;doublej=1;doublen=1;while(true){Console.WriteLine("a{0}:a{1}=
publicclassFibonacci{publicstaticvoidmain(Stringargs[]){inti=1,j=1;for(intn=1;n
#include#includeusingnamespacestd;intf[1000];//数组记录计算结果intfa(inti){if(i==0)//递归结束条件{f[i]=0;retur
#include"stdio.h"intfun(intm){if(m==1){return1;}elseif(m==2){return1;}else{returnfun(m-1)+fun(m-2);}
应该定义成长整型,要不然会数据溢出,下面用两种方法实现此问.个人认为,第二种方法好.第一种:循环#includevoidmain(){inti;longf1=1,f2=1;printf("前15组菲薄
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-
#includeintfibo(intn){if(nreturn1;elsereturnfibo(n-1)+fibo(n-2);}intmain(){intn;scanf("%d",&n);print
cleardimea[20]a[1]=1a[2]=1fori=3to20a[i]=a[i-1]+a[i-2]endforfori=1to30?a[i]if(i%5=0)?endifendfo
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
