程序1.用递归法编写一个函数fac,求n!的值.将该函数存放在file1.c.

#include"iostream.h"voidmain(){doubleF,c;coutF;c=(F-32)*5/9;cout

#includeunsignedintFibonacci(intn);intmain(void){inti;for(i=1;i

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

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

PrivateFunctionF(nAsLong)AsLongIfn>2ThenF=F(n-1)+F(n-2)ElseF=1EndIfEndFunctionPrivateSubCommand1_Cli

(x,y)=x+y(x>=0&y>=0)f(x,y)=x+y*y(x>=0&y

用递归法计算n!用递归法计算n!可用下述公式表示：n!=1(n=0,1)n×(n-1)!(n>1)按公式可编程如下：longff(intn){longf;if(n
