I guess I don\'t fully understand how destructors work in C++. Here is the sample program I wrote to recreate the issue:
I have problems understanding why when I create two or more nodes (as shown below), the function void del_end()will only delete the char name[20] and not the whole node .How do I fix this problem with
Consider the following code: void foo() { { CSomeClass bar; // Some code here... goto lab开发者_如何学Goel;
I know that my destructors are called on normal unwind of stack and when exceptions are thrown, but not when exit()开发者_C百科 is called.
There is a simple and well-known pattern to avoid the static initialization fiasco, described in section 10.13 of the C++ FAQ Lite.
I have a python object which wraps a sensitive and important resource on the system. I have a cleanup() function which safely releases various locks used by the object.
Suppose I have a class like this: #include <iostream> using namespace std; class Boda { private: char开发者_StackOverflow *ptr;
Is it possible to get destructors in Lua w/o using userdata? http://www.lua.org/notes/ltn006.html looks promising (in fact exactly what I want); except it\'s a path for Lua 4.0.
I have an object that can be used, or eaten, or whatnot in PHP. In any case, it ends up gone. I have an abstract protected method called activate(), which is called by a public method useItem().
This is an example of my co开发者_运维问答des: template <typename T> struct MyStruct { T object;
