  • 基础测试

    1、编写程序计算1+2+3+....+100的和。

                                int i;

                                int sum = 0;

                                for (i = 0; i < 101; i++) {

                                         sum += i;

                                         }

                                Console.WriteLine("{0}",sum);

                                Console.ReadKey();

    2、已知一个int数组, 编程从数组中获取最大数。

                       static int MaxValue(int[] intArray) {

                                int maxVal = intArray[0];

                                for (int i = 0; i < intArray.Length - 1; i++)

                                { if (intArray[i] > maxVal)

                                         maxVal = intArray[i]; }

                                 return maxVal;

                       }

                       static void Main(string[] args)

                       {

                                int[] myArray = {129, 8, 3, 6, 2, 5, 9, 3, 0, 2 };

                                int maxVal = MaxValue(myArray);

             Console.WriteLine("最大数为:{0}", maxVal);

             Console.ReadKey();         

                       }

    3、用户输入一个“2008-01-02”格式的日期,分析用户输入的日期然后按照“2008年1月2日”的格式重新输出。

                       static void Main(string[] args) {

                                string time = "2008-1-2";                    

                                string[] a = time.Split('-');

                                Console.WriteLine("{0}" + "年" + "{1}" + "月"+"{2}"+"日", a[0],a[1],a[2]);

                                Console.ReadKey();

                       }

    4、编写一个类Person,为Person类定义年龄、姓名两个属性,并且定义一个SayHello方法,方法执行时输出“我是***我的年龄是***”;定义一个Chinese类从Person类继承。

             class Program {

     

                       static void Main(string[] args) {

                                Chinese c = new Chinese();

                                c.Age = 24;

                                c.Name = "smile";

                                c.SayHello();

                       }

             }

             abstract class Person {

                       private string name;

                       private int age;

                       public int Age {

                                get { return age; }

                                set { age = value; }

                       }

                       public string Name {

                                get { return name; }

                                set { name = value; }

                       }

                       public abstract void SayHello();

             }

             class Chinese:Person

             {

                       public override void  SayHello(){

                                Console.WriteLine("我是"+Name+"我的年龄是:"+Age);

                                Console.ReadKey();

                       }

             }

    5、不借助于Dreamweaver、VisualStudio等开发工具,使用记事本等文本编辑器编写下面的HTML页面:

    <html>

          <head>

               <title>登录</title>

    <style type="text/css">

    #tb{

            border-bottom:1px solid #000;

            border-right: 1px solid #000;

    }

    #tb td,th{

             border-top: 1px solid #000;

            border-left: 1px solid #000;

    }

    .centerz{text-align:center;}

    .left{text-align:right;}

    </style>

          </head>

    <body>

    <form>

    <table cellspacing=0 cellpadding=13 id="tb">

    <tr >

    <th colspan="2" >必填信息</td>

    </tr>

    <tr>

    <td class="left">登录名</td>

    <td><input type="text" />(只能用英文、数字和下划线)</td>

    </tr>

    <tr>

    <td class="left">密码</td>

    <td><input type="password"/>(密码必须大于5位,区分大小写)</td>

    </tr>

    <tr>

    <td class="left">确认密码</td>

    <td><input type="password"/></td>

    </tr>

    <tr>

    <td class="left">邮件地址</td><td><input type="text" /></td>

    </tr>

    <tr>

    <td class="left">确认邮件地址</td><td><input type="text" /></td>

    </tr>

    <tr>

    <td colspan="2" class="centerz"><input type="submit" value="提交"/><input type="reset" value="重填"/></td>

    </tr>

    <tr >

    <td colspan="2" ></td>

    </tr>

    </table>

    </form>

    </body>

    </html>

     

    6、使用JavaScript验证第5题的HTML表单。要求如下:“登录名”必须是字母数字或下划线, 不能以数字开头;密码为6-16位字母、数字或者下划线.;密码和确认密码一致;邮件地址是正确的邮件地址格式;邮件地址和确认邮件地址一致;。(选做题 20分)
