Explanation
不能有 CV 限定符,在 C++ 中 CV 限定符指const
和volatile
。
- 非成員函式
在 C++ 中,普通函式(非類的成員函式)不能有 CV 限定,即const
和volatile
限定。即非類的成員行數,用const
進行修飾:
int test() const //這是不對的,普通函式(非成員函式不能有CV約束)
{
//實現
}
- 靜態函式
在 C++ 中,靜態成員函式(static
成員函式)不能有 CV 限定,即const
和volatile
限定。即類的靜態成員函式,也不能有 CV 約束:
class Test
{
public:
static int test_fun() const; //這個是不允許的。
}
