用C程序低通滤波器，可以直接编译！！使用(C program used low-pass filter, you can direct the compiler! ! Use)

vc++将汉字转换成拼音的程序源代码，非常有意思，它不单纯转换为拼音，而且还可以设置分隔符，按规则转换：全部转换成大写、全部转换成小写、将首字母大写，还可以转换为现在流行的拼音首字母简写，也就是只取拼音首字母，按大写或小写提取，看来确实非常有意思也非常实用哦。(vc++ will be converted into Chinese characters spelling the source code, very interesting, it does not simply converted to Pinyin, but also can be set separators in accordance with the rules of conversion: the conversion of all upper case, all converted to lowercase to uppercase the first letter, but also can be converted to Pinyin is now the first letter of the popular shorthand, that is, only the first letter of alphabet, based on extraction of upper or lowercase, it seems very interesting indeed Oh also very practical.)

Java实现窗体右键菜单，简约易操作的窗体菜单，这是一个相当易懂的制作实例。 　　super( "右键弹出菜单" ); //调用父类构造函数 　　ChangeColorAction action = new ChangeColorAction(); //菜单项事件处理 　　String[] str = {"Blue","Pink","Yellow","Red","Orange"}; //菜单项名称 　　ButtonGroup colorGroup=new ButtonGroup(); //实例化按钮组 　　popupMenu=new JPopupMenu(); //实例化弹出菜单 　　items=new JRadioButtonMenuItem[5]; //初始化数组 　　for (int i=0;i　　 items[i]=new JRadioButtonMenuItem(str[i]); //实例化菜单项 　　 popupMenu.add(items[i]); //增加菜单项到菜单上 　　 colorGroup.add(items[i]); //增加菜单项到按钮组 　　 items[i].addActionListener(action); //菜单项事件处理 　　} 　　addMouseListener(new MouseAdapter(){ //窗口的鼠标事件处理 　　 public void mousePressed( MouseEvent event ) { //点击鼠标 　　 triggerEvent(event); //调用triggerEvent方法处理事件
