编写递归函数int fid(n),递归公式如下:

#includeintdigit(intn,intk){returnk>1digit(n/10,k-1):n%10;}intmain(){printf("%d",digit(12345,3));}

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))

longpower(intm,intn){doublep=1;if(n>0){p=m*power(m,(n-1));returnp;}}voidmain(){intm,n;longk;scanf("%

cludestdio.hvoidmain(){intmax_4(inta,intb,intc,intd);inta,b,c,d,max;printf("Pleaseenterintergernumbe

#includeusingnamespacestd;doublefun(intn,doubleh){if(n==1)returnh;elseif(n再问：usingnamespacestd;这句

#includeintmain(){floatF(intm,intn);intn,m;floaty;printf("请输入两个数据:\n");scanf("%d%d",&m,&n);y=F(m,n);

我有我给你.

#includelongfac(intn){inti;longx=1;for(i=2;i再问：谢谢咯！可是我说的是递归法哦！再答：#includelongfac(intn){if(n==0)retur

#include <stdio.h>char* dg(char* instr, char* outstr, char* 

程序已经调试过了,你看下吧,可以的话给个好评#include"iostream"usingnamespacestd;floatpower(floata,intn){if(n==1)returna;el

你先了解这个函数的作用,结果就是n*(n/(2^1)*(n/(2^2))*(n/(2^3))*(n/(2^4))……*1n*(n/2)*(n/4)*(n/8)*……*1while(n>=0){if(n

if(n==1)\x05\x05return1;你可以改成n==0或者改成returnx取其中一种就可以了

#includedoublef(doublex,intn){if(n==1)returnx;else{doubled=1.0;inti;for(i=1;i

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
