编写递归函数double fac(int n)计算n!

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

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))

#includedoubleH(intn,doublex){if(x>1){if(n==0)return1.0;//H0(x)=1;if(n==1)return2.0*x;//H1(x)=2x;//直

#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

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

不想吐槽百度的排版.再问：大神，你在不在，我想拜你为师。再答：我是不是大神，真的。。。再问：你这个是C++吗，我还没学过呢我现在正在学C再答：上一个回答多了个是字你竟然没发现，打多了。。然后，我水平一
