第一题题目: 1、利用循环实现“计算斐波那契数列第n项”的函数,F(n)=F(n-1)+F(n-2),其中 F(1)=F(2)=1n>=3。(假设所求斐波那契项不超出整型数据表示范围)注:不可使用全局变量。 #include <iostream>int Fibonacci(int n){ if (n == 1 || n == 2) return 1; else return Fibonacci(n - 1) + Fibonacci(n - 2);}int main(){ int n; std::cout << "输入n的值(n>=3)" << std::endl; std::cin >> n; if (n >= 1) { std::cout << "数列第n项是" << Fibonacci(n); } return 0;} 第二题题目: 2、使用函数 ...
