求c#控制台应用程序例题答案 1、 创建一控制台应用程序，用来判断从用户输入年份开始到2500年的闰年并打印

Answer 1

using System;
using System.Collections.Generic;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int input = 0;
const int max = 2500;
List<int> result = new List<int>();
Console.WriteLine("输入一个年份");
while (!int.TryParse(Console.ReadLine(), out input))
{
Console.WriteLine("输入错误");
}
for (int index = input; index <= max; ++index)
{
if (index % 100 != 0 && index % 4 == 0 || index % 400 == 0)
{
result.Add(index);
}
}
input = 0;
foreach (int output in result)
{
Console.Write(output + "\t");
if (++input % 6 == 0) Console.WriteLine();
}
Console.WriteLine();
Console.WriteLine("按任意键退出");
Console.ReadKey();
}
}
}

Answer 2

int y = 0;
for (int i = 1; i <= 1000; i++)
{
if (i % 7 == 0)
{
y++;

Console.WriteLine(y + " " + i);

max += i;

if (y % 5 == 0)
{
Console.WriteLine("count every five: " + max);
max = 0;
}
}

}
