(C++/JAVA)斐波那契数列

(C++/JAVA)有一对兔子，从出生后第3个月起每个月都生一对兔子，小兔子长到第三个月后每个月又生一对兔子，假如兔子都不死，问每个月的兔子对数为多少？

C++:

#include<iostream>
using namespace std;
int FBNQ(int m){
	if (m == 1 || m == 2)
		return 1;
	else
		return FBNQ(m - 1) + FBNQ(m - 2);
}
int main(){
	int n;
	int p = 1;
	cin >> n;
	while (p <= n){
		cout << FBNQ(p) << "  ";
		p++;
	}
	cout << endl;
}

JAVA:****(略改：输出两行斐波那契数列)
