3)const

int a=1;
int b=2;
(1) int *const cpi=&a;//const修饰指针,cpi=&b不允许,*cpi=b允许
(2) const int* pic=&a;//同int const* pic=&a,指针的指向为常量,pic=&b允许,*pic=b不允许
(3) int* const cpic=&a;//同1
(4) const int* const cpic=&a;//指针和指针的指向都为常量,对*cpic/cpic的赋值操作都不允许
(5) const int ic=12;//ic为常量,赋值操作不允许
(6) int const pc=12;//同5

4)

 //  隐藏WINDOWS系统任务栏
 ::ShowWindow (::FindWindow("Shell_TrayWnd",NULL),SW_HIDE);

 // 显示WINDOWS系统任务栏
    ::ShowWindow (::FindWindow("Shell_TrayWnd",NULL),SW_SHOW);

5)在控制台注册DLL
