本文概述
- 无递归C语言的斐波那契数列
- Fibonacci系列在C中使用递归
编写fibonacci系列程序的方法有两种:
- 斐波那契数列,无递归
- 斐波那契数列使用递归
#include<
stdio.h>
int main()
{
int n1=0, n2=1, n3, i, number;
printf("Enter the number of elements:");
scanf("%d", &
number);
printf("\n%d %d", n1, n2);
//printing 0 and 1
for(i=2;
i<
number;
++i)//loop starts from 2 because 0 and 1 are already printed
{
n3=n1+n2;
printf(" %d", n3);
n1=n2;
n2=n3;
}
return 0;
}
输出:
Enter the number of elements:15
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
Fibonacci系列在C中使用递归我们来看一下使用递归的c中的fibonacci系列程序。
#include<
stdio.h>
void printFibonacci(int n){
static int n1=0, n2=1, n3;
if(n>0){
n3 = n1 + n2;
n1 = n2;
n2 = n3;
printf("%d ", n3);
printFibonacci(n-1);
}
}
int main(){
int n;
printf("Enter the number of elements: ");
scanf("%d", &
n);
printf("Fibonacci Series: ");
printf("%d %d ", 0, 1);
printFibonacci(n-2);
//n-2 because 2 numbers are already printed
return 0;
}
【c语言中的斐波那契数列】输出:
Enter the number of elements:15
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377
