代码摘要：

switch (splitCountA)
{
case 0:
//AfxMessageBox("0");
break;
case 1:

case 6:

  for (int k=1;k<7;k++)
  {
  strtemp.Format("-%d-",k);
  dc.TextOut(rectWnd[k].left,rectWnd[k].top,strtemp,sizeof(strtemp)-1);
  dc.Rectangle(&rectWnd[k]);//画空心的矩形
  }
  dc.SelectObject(pOldBrush);//恢复画刷

  break;
case 7:
   AfxMessageBox("7");
   break;

//default:
// AfxMessageBox("default");
// break;
}

出错的提示为一连串的：

error C2360: initialization of 'k' is skipped by 'case' label

原因为：

如果变量定义在switch外面那么生命期才能到达case内部

像楼主的定义方法，a是作用域是switch块，又因为它是在case 1：这个lable后定义的，假设程序运行时n直接匹配case 2：的话，此时a就是未定义的，这就与a的作用域矛盾，所以编译器不允许这样的定义。
可以像2楼的第二种方法那样定义，此时a的作用域是case 1：lable后那个大括号标识的局部域，就不会产生像上边说的矛盾了

解决办法，将case语句段放在花括号{}中，或者将变量的定义放在switch语句外
