我尝试使用以下代码示例删除一个 ptr:
int* data = new int(1);
int* p = NULL;
p = data;
*p = 3;
delete p;
// Prints 3
cout << *p << endl;
//Prints 3
cout << *data << endl;
The last two lines of code prints 3, and my question is what is deleted after
delete p? According to what it prints out from the last two lines of code, it seems like nothing is deleted 0.0~~
有人请给我解释一下。提前谢谢大家。
