本程序用递归方法计算Fibnacci数列的前20项

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

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

longadd(intn){intt=n-1;if(t>1){longresult=n*t;longsum=result+add(t);returnsum;}else{returnn;}}楼上的方法,

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

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

你好.你的递归函数里在递归调用时忘记return了.应该是returngcd(m,n);下面是改过的代码.我在代码里加了些注释.#includeintgcd(intm,intn){intr,t;//若
