1. 用递归方法编写求斐波那契数列的函数,返回值为长整型.斐波那契数列的定义为

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

他的代码return1,是指序列从1开始,1,1,2,3,从0开始的话,改成if(k==0)return0;elseif(k==1)return1;elsereturnfib(k-1)+fib(k-2

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))

因为用了很没有效率的递归,所以出结果有点慢#includef(int);main(){inti,s=0;for(i=1;i

#includeusingnamespacestd;intmain(){intn,a=1,b=2;cout再问：^那这个是什么符号，这个没学过，有用temp做的么？再答：是位运算的异或符号；也可以用t
