你不是因为你没有分配任何记忆;那个temp1指针指向

到一个不能写入的文字字符串，也不能删除它。


亲切的问候，


Jos

You don''t because you haven''t allocated any memory; that temp1 pointer points
to a literal string that can''t be written to nor can it be deleted.

kind regards,

Ok


我也将此字符串传递给类中的函数


LineText :: LineText（wchar_t * message）

{

sDisplayText = message;

}


所有这些都可以解决任何问题，如果我不删除sDisplayText使用delete [] sDisplayText


我现在很困惑。如果它可以作为指针被传递到它被销毁的时候？

Ok

I am also passing this string to a function in a class

LineText::LineText(wchar_t* message)
{
sDisplayText = message;
}

All of them work with out any problem, if I don?t delete sDisplayText using delete[]sDisplayText

I am confused now. If it can be passed to a function as pointer when does it get destroyed?

确定


我也将这个字符串传递给一个函数一个班级


LineText :: LineText（wchar_t * message）

{

sDisplayText = message;

}


如果我不在类的析构函数中使用delete [] sDisplayText删除sDisplayText，它们都可以解决任何问题。

我现在很困惑。如果可以将它作为指针传递给它什么时候被销毁？


如果它可以被传递，它是否会以某种方式结束直到程序结束？

Ok

I am also passing this string to a function in a class

LineText::LineText(wchar_t* message)
{
sDisplayText = message;
}

All of them work with out any problem, if I don?t delete sDisplayText using delete[]sDisplayText in the destructor of the class.

I am confused now. If it can be passed to a function as pointer when does it get destroyed?

If it can be passed around does it remain somehow until the program ends?
