C++生成斐波拉其数列

该方法作为一种演示功能左右，运行较慢。

1#include <iostream>

3using namespace std;

5class Fibonacci{
6public:
7    int a, b, c;
8    void generate(int);
9};

11void Fibonacci::generate(int n){
12    a = 0; b = 1;
13    cout << a << " " <<b;
14    for(int i=1; i<= n-2; i++){
15        c = a + b;
16        cout << " " << c;
17        a = b;
18        b = c;
19    }
20}

22int main()
23{
24    cout << "Hello world! Fibonacci series" << endl;
25    cout << "Enter number of items you need in the series: ";
26    int n;
27    cin  >> n;
28    Fibonacci fibonacci;
29    fibonacci.generate(n);
30    return 0;
