1.统计一个四行五列的二维规则整形数组中，奇数和偶数的个数。
using System
using System.Collections.Generic
using System.Linq
using System.Text
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int[,] ia = new int[4, 5]
int ji = 0,ou=0
Console.WriteLine("请您依次输入20个值")
for (int i = 0 i < 4 i++)
{
for (int j = 0 j < 5 j++)
{
Console.WriteLine("请输入 ia[{0},{1}] 的值:", i, j)
ia[i, j] = int.Parse(Console.ReadLine())
if (ia[i, j] % 2 == 0)
{
ou++
}
else
{
ji++
}
}
}
Console.WriteLine("此数组中奇数的个数为" + ji + "此数组中偶数的个数为" + ou)
Console.ReadLine()
}
}
}
2.编写一个包含学生基本资料的结构类型数据，要求包括姓名，*别，年龄，身高，体重等
并包括一个有参构造函数，参数列表为用户输入的姓名，*别，年龄，身高，体重。
using System
using System.Collections.Generic
using System.Linq
using System.Text
namespace ConsoleApplication2
{
struct MyStruct
{
public string name
public string xingbie
public int age
public double hight
public double weight
//public MyStruct()
//{
// name = "张三"
// xingbie = "男"
// age = 20
// hight = 1.70
// weight = 50
//}
public MyStruct(string n, string x, int a, double h, double w)
{
name = n
xingbie = x
age = a
hight = h
weight = w
}
}
class Program
{
static void Main(string[] args)
{
Console.WriteLine("请输入您的基本信息")
Console.WriteLine("请输入您的姓名")
string xm = Console.ReadLine()
Console.WriteLine("请输入您的*别")
string xb = Console.ReadLine()
Console.WriteLine("请输入您的年龄")
int ae =int.Parse( Console.ReadLine())
Console.WriteLine("请输入您的身高")
double ht = double.Parse(Console.ReadLine())
Console.WriteLine("请输入您的体重")
double wt = double.Parse(Console.ReadLine())
MyStruct s1 = new MyStruct(xm, xb, ae, ht, wt)
Console.ReadLine()
}
}
}
3.定义一个车辆（Vehicle）基类，具有Run，Stop等方法，具有Speed（速度），MaxSpeed（最大速度），Weight（重量）等属*。
然后以该类为基类，派生出bicycle、car等类，并编写验证程序。
using System
using System.Collections.Generic
using System.Linq
using System.Text
namespace ConsoleApplication1
{
class Vehicle
{
int speed
public int Speed
{
get {return speed}
set {speed = value}
}
int maxSpeed
public int MaxSpeed
{
get {return maxSpeed}
set {maxSpeed = value}
}
int weight
public int Weight
{
get {return weight}
set {weight = value}
}
public virtual void Run()
{
Console.WriteLine("Vehicle Run.")
}
public virtual void Stop()
{
Console.WriteLine("Vehicle Stop.")
}
}
class Bicycle : Vehicle
{
string material
public string Material
{
get { return material }
set { material = value }
}
public override void Run()
{
Console.WriteLine("Bicycle Run.")
