斐波那契数列c++while

以下是使用C++ while循环实现斐波那契数列的代码：

#include <iostream>
using namespace std;

int main() {
    int n;
    cout << "请输入要求的斐波那契数列的项数：";
    cin >> n;

    int f0 = 0, f1 = 1, f2;
    cout << "斐波那契数列前" << n << "项为：";
    if (n >= 1) {
        cout << f0 << " ";
    }
    if (n >= 2) {
        cout << f1 << " ";
    }
    for (int i = 3; i <= n; i++) {
        f2 = f0 + f1;
        cout << f2 << " ";
        f0 = f1;
        f1 = f2;
    }
    cout << endl;

    return 0;
}
