<P>不错不错，只是密码输入后，不能用“Backspace”修改。。</P><P>我在里面填了几句，实现修改的功能。</P><P> while((c=getch())!=13)
  {
   if(c==8){i--;gotoxy(46+i,12);cprintf(" ");gotoxy(46+i,12);}
   else{
   aa=c;
   gotoxy(45+i,12);
   cprintf("*");
   if(i&gt;20) break;}
  }</P>

<P>因为你是直接拷贝放在编译器里面执行的！这里网页上有一些不可见的控制符号！所以提示有非法字符！注意将一些空格重新输入一下就行了！</P>
