怎么实现键盘控制循环问题啊？

请知道的高手，多多指教。。。。 即有： 
<TABLE borderColor=#cccccc cellSpacing=2 cellPadding=3 width=164 bgColor=#ffffff border=1>

<TR>
<TD> 菜单1 菜单2 菜单3</TD></TR></TABLE> 
<TABLE borderColor=#cccccc cellSpacing=2 cellPadding=3 width=173 bgColor=#ffffff border=1>

<TR>
<TD> 主菜单</TD></TR></TABLE> 
<TABLE borderColor=#cccccc cellSpacing=2 cellPadding=3 width=276 bgColor=#ffffff border=1>

<TR>
<TD> 执行菜单X </TD></TR></TABLE> 当按上下键时，在菜单1--3之间切换 按退格键时，回主菜单 在菜单1--3某项时按回车，进入执行。[em03]

又没人知道？哎~~~[em13]

TC还是VC？

yuerhb 发表于 2007-7-10 16:41

TC啊！！怎么做知道吗？

静态的可以用 key = getch() ; 动态的 key = bioskey(0) ;

谢谢，这个我知道！只是循环的过程我老是做的有缺陷！菜单不光这两页，很多，他们之间的切换挺麻烦的。。。。[em03]

假设将主菜单已经存放到数组char *main_menu[10];//指针字符串数组 一级菜单放在数组char *sub1_menu[10];//指针字符串数组 二级菜单放在数组char *sub2_menu[10];//指针字符串数组 //切记指针字符串数组必须事先分配内存 // for (i=0;i<10;i++) main_menu[i] = (char *)malloc(100*sizeof(char)); void main() { //初始化 依次显示主菜单项 　 //while (1) { 1、显示亮条菜单项 2.获取键码 3.1上键，则亮条上移 　　　　　 3.2下键，则亮条下移 　　　　　 3.3回车键，则执行相应的程序　　　 }　 }
