函数练习

1、兔子问题的函数做法

主要代码：

static void Main(string[] args) { Program method = new Program(); Console.Write("请输入月数："); int mouth = int.Parse(Console.ReadLine()); Console.WriteLine(method.rabbit(mouth)); Console.ReadLine(); } public int rabbit(int mouth) { int y = 1; int x = 0; int c = 0; int s = 1; if (mouth >= 1 && mouth <= 12) { for (int i = 1; i <= mouth; i++) { if (i == 1) { y = 1; x = 0; c = 0; } else { c += x; x = y; y = c; } s = c + x + y; } } return s; }

结果：

2、卖养，每过一个村庄卖掉总数的二分之一零一只，过了七个村庄后还有两只，问最初有多少只羊。

主要代码：

static void Main(string[] args) { Program method = new Program(); Console.WriteLine(method.goat(2)); Console.ReadLine(); } public int goat(int num) { for (int i = 8; i > 1; i--) num = (num + 1) * 2; return num; }

结果：

3、篮球从20米落下，反弹原来的3/4，输入弹起次数，算出总长度（有返回值，有参数）

主要代码：

static void Main(string[] args) { Program function = new Program(); Console.Write("请输入弹起次数："); int n = int.Parse(Console.ReadLine()); double h = 20; Console.WriteLine(function.hight(h, n)); Console.ReadLine(); } public double hight(double h, int c) { double sum = 0; for (double i = 0; i < c; i++) { sum += 2 * h; h *= 0.75; } sum -= 20; return sum; }

结果：

4、随机出现32以内的6个红球，随机出现16以内的1个蓝球，组成彩票号码（无参数，有返回值）

主要代码：

static void Main(string[] args) { Program function = new Program(); int[] lottery = function.lottery(); foreach (int a in lottery) Console.Write(a + "\t"); Console.ReadLine(); } public int[] lottery() { Random red = new Random(); int[] array = new int[7]; for (int i = 0; i < 6; i++) { int Red = red.Next(1, 33); array[i] = Red; for (int j = 0; j < i; j++) { if (array[j] == Red) i--; } } Random blue = new Random(); int Blue = blue.Next(1, 17); array[6] = Blue; return array; }

结果：

5、打印等腰三角形

主要代码：

static void Main(string[] args) { Program function = new Program(); Console.Write("请输入行数："); int h = int.Parse(Console.ReadLine()); function.triangle(h); Console.ReadLine(); } public void triangle(int h) { for (int i = 0; i <= h; i++) { for (int j = h - 1; j >= i; j--) Console.Write(" "); for (int k = 0; k < i; k++) Console.Write("*"); for (int n = 0; n < i - 1; n++) Console.Write("*"); Console.WriteLine(); } }

结果：
