2.java程序MP3播放器源代码
3.用C语言做数字时钟每走一秒响一次,求大神告诉源代码
timemԴ??
1)
启动visual basic6.0 ,打开一个新的源码时代在哪标准工程。
2)
在窗体上Form1上添加6个标签空间(Label) 2个命令按钮(CommandButton)和1个计时器(Timer)。命令按钮的vb 自动提醒源码Caption属性分别为“启动”“停止”
Timer1的Interval属性为
Label1 Label2 Label3的Caption属性分别为“开始时间”“结束时间”“经过时间” Timer1的Enable属性为False
3)代码
Dim Starttime As Variant
Dim End time As Variant
Dim Elapsed As Variant
Private Sub cmdStart_Click()
'显示开始时间
lblStart.Caption=Time$
Starttime=Now
'启动时钟控件
Timer1.Enabled=Ture
End Sub
Private Sub cmdStop_Click()
'记录停止时间
Endtime=Now
'关闭时钟控件
Timer1.Enabled=False
'显示经过时间
lblApaed.Caption=Format(Endtime-Starttime,"hh:mm:ss"
End Sub
Private Sub Timer1_Timer()
lblStop.Caption=Time$
End Sub
以上是用VB6.0实现的

用C语言做数字时钟每走一秒响一次,编程源码 图片旋转求大神告诉源代码
“响一次”需要牵涉到图形编程中的音乐播放问题,需要自己下载图形编程相关库文件,吃鸡辅助源码具体实现请自己在TODO里添加播放音乐的代码数字时钟的实现很简单,运用time.h相关函数即可
#include<stdio.h>#include<stdlib.h>
#include<time.h>
time_t oldt=-1;
struct tm *p;
bool Printdate()
{
time_t t=time(NULL);
if(t!=oldt)
{
oldt=t;
p=localtime(&t);
system("cls");
printf("%d/%d/%d 周",+p->tm_year,1+p->tm_mon,p->tm_mday,p->tm_hour,p->tm_min,p->tm_sec);
switch(p->tm_wday)
{
case 1:printf("一");break;
case 2:printf("二");break;
case 3:printf("三");break;
case 4:printf("四");break;
case 5:printf("五");break;
case 6:printf("六");break;
case 7:printf("日");break;
}
printf(" %d:%d:%d ", p->tm_hour, p->tm_min, p->tm_sec);
return 1;
}
return 0;
}
main()
{
while(1)
if(Printdate())
