vb歌手大赛评分系统代码
用VB编写一个歌手大赛评分系统这样的问题回复内容太多，百度知道的字数限制，回答不了的。其实你可以直接买现成的评分系统，象天纵评委评分系统，支持手工打分、电脑打分、无线评分器评分、手机或平板打分，有在线租用，也可以本地安装版本。能满足各种比赛的评委打分。

Q1: 一个java歌唱比赛评分应用程序，急需，明晚上10点截至
每个歌手可以看成一个对象歌手比赛系统java代码，这样就可以建一个歌手歌手比赛系统java代码的类，添加一些属性和get，set方法 ，主程序可以将路人的对象保存起来，评委打分可以通过循环来对每个歌手进行打分，将打好的分保存起来，进行数据处理，存到一个数组或者链表中，查找时可以通过输入编号得到对应的选手，再通过选手得到对应的分数歌手比赛系统java代码；排序得分就更简单了，使用排序算法就可以解决，什么冒泡，快速排序都行的。。。楼主代码还得自己敲
Q2: 用JAVA编写 “十个评委给一个歌手打分，求出打分的平均值，（去掉最高分和最低分）”怎么编写
class Test
{
public static void main(String []args)
{
int a[]={4,458,53,44,84,22,86,114,98,41};
int q=0;
for(int i=0;i10;i++)
{
for(int j=0;j10;j++)
{
int temp=0;
if(a[i]a[j])
{
temp=a[i];
a[i]=a[j];
a[j]=temp;
break;
}
}
}
a[0]=0;
a[9]=0;
for(int x=0;x10;x++)

Q5: 用C++写歌手比赛系统 要求：对一次歌手比赛的成绩进行管理，输入每个选举的数据包括
classCourse{char[50]name;floatresult;}classStudent{Course*course;char[20]name;}类的结构就是这样了。其他无非增删改差楼主自行实现。
