I caught that I use references not understanding开发者_Python百科 how they really work (that\'s why I use them not so often).
If I have a definition in a class header such as this: vector<baddie*> baddies; which I then initialise in the constructor like this:
I have just started learning C. void function(char *str1, char *str2) { printf(\"%p\\n\", str1); printf(\"%p\\n\", str2);
Is it possible to store pointers to objects in boost property trees, and then use an iterator to retrieve the data? I\'m trying to do something like:
In the f开发者_运维问答ollowing code segment vector<SceneObject *> sceneObjs; vector<SceneObject *>::iterator iter;
template<typename T> someclass<T>& operator=(const someclass<T>& other) { typename std::vector<T *>::const_iterator rhs;
If I have an array declared like this: int a[3][2]; then why is: sizeof(a+0) == 8 whereas: 开发者_如何学Pythonsizeof(a)== 24
For a program, I would like to make an array copy of the arguments sent in by command line using malloc().
What causes the output \"Hello\" when I enable -O for gcc ? Shouldn\'t it still segfault (according to this wiki) ?
In writing a response, I wrote some code that challenged my assumptions on how const pointers work. I had assumed const pointers could not be deleted by the delete function, but as you\'ll see from th
