1 2 ..... n!用递归法输出

#include"stdio.h"intgys(intm,intn){if(n>1){if(m%n!=0){returngys(n,m%n);}elsereturnn;}}intmain(){intm

#include"stdio.h"intfact1(intn){if(n==1||n==0)return1;elsereturnn*fact1(n-1);}intfact2(intn){inti,t=

#include#include//note:只能处理n是正整数的情况floatf(floatm,intn){assert(n>=0);if(n==0)return1.0;if(n==1)return

#include/*非递归求：f(1)+f(2)+...+f(m)其中f(n)=n*(n+1)*/unsignedintsum_fn(unsignedintm){intn,sum=0;for(n=1;

这个东西关键是递归算法的确定,需要一点数学知识.#include//递归计算函数intcalc(intx){if(xif(x==1){return1;}elseif(x==2){return3;}el

//很简单,应该是答案印错了//不过这样才是正确的递归方式doublelegendre(intn,doublex){if(n==0)return1;elseif(n==1)returnx;elsere

#include#defineCOL10//一行输出10个longscan(){//输入求fibonacci函数的第N项intn;printf("InputtheN=");scanf("%d",&n)

用VB写的~PrivateSubForm_Load()Dimfn&,f1&,f2&,n%f1=1:f2=1n=Val(InputBox("请输入n"))fn=f1+f2Printf1Printf2Pr

#includemain(){intx,n;longf(intx,intn);scanf("%d%d",&x,&n);printf("%ld",f(x,n));system("PAUSE");}lon

代码如下:OptionExplicitPrivateSubCommand1_Click()MsgBoxP(2,2)EndSubFunctionP(ByValnAsInteger,ByValxAsDou

longfac(int);这一步应该为longfac(int,float);y=fac(n);这一步应该为：y=fac(n,x);elseif(n=0)f=1;这一步应该为：elseif(n==0)f

#includeintf(inti){if(i==1||i==2)return1;elsereturnf(i-1)+f(i-2);}voidmain(){intn,j;scanf("%d",&n);f

要写出递推式：f(x,n)=1+x*f(x,n-1)doublef(doublex,intn){if(n==0)return(1.0);elsereturn(1.0+x*f(x,n-1));}
