该方法作为一种演示功能左右，运行较慢。

#include <iostream>using namespace std;class Fibonacci{
public:
int a, b, c;
void generate(int);
};void Fibonacci::generate(int n){
a = ; b = ;
cout << a << " " <<b;
for(int i=; i<= n-; i++){
c = a + b;
cout << " " << c;
a = b;
b = c;
}
}int main()
{
cout << "Hello world! Fibonacci series" << endl;
cout << "Enter number of items you need in the series: ";
int n;
cin >> n;
Fibonacci fibonacci;
fibonacci.generate(n);
return ;
