用递归函数输出斐波拉契数列前20项(每行4个)

为用了很没有效率的递归,所以出结果有点慢#includeiostream.h

递归函数如下：首先斐波拉楔数列的前n项和递推公式为S（n）=S（n-1）+S（n-2）+1；(根据通项公式a[n]=a[n-1]+a[n-2]很容易推导出来)递归函数如下所示;intsum_Fibon

#includefib(intn){if(n==0)return(0);elseif(n==1)return(1);elsereturn(fib(n-1)+fib(n-2));}main(){intn

//fibonacci数列:11235813213455...#includedoublefib_val[100]={0};doublefibonacci_1(intn)//递归,计算时间长,n最好不
