Otherwise, write for your audience: the next contributor who will need to understand your code. Compared to Q_GLOBAL_STATIC, and assuming that MyType is a class or struct that has a constructor, a destructor, or is otherwise non-POD, the above has the following drawbacks: it requires load-time initialization of MyType (that is, the default constructor for MyType is called when the library or application is loaded); As you said, if some of these destructors touch already destroyed objects, your program could crash. The __del__() method is a known as a destructor method in Python. Compilers can end messages between peer upon compiler or conversion operator requires a global destructor declaration is.

Thomas1965 (4571) For some reason GCC compiles this code. An important difference between function declarations and class declarations is that while functions can be called in code that appears before they are defined, classes must be defined before they can be constructed. How to fix variable declaration and global constructor warnings? I can't use std::vector of auto_ptr - should i use shared_ptr? The first items of the iterable are assigned, the other shall declare it as one of the same type. The latter 3 aren't strictly related through phrasing I believe they are still caused by extra compiler checks that were inadvertently turned on due to what was described in the thread that @aha_1980 linked. (It's my own thing, not an exercise from the book.) Answer (1 of 3): Sometimes you must create an empty destructor of a class. It could be better if I would have done a std::string(base62, sizeof(base62)/sizeof(base62[0])) instead, though. Answer (1 of 3): You may declare the destructor of a base class as pure virtual in the class declaration (as in a header or .h ), but you MUST provide a body for the base class destructor in the class definition (source or .cpp). Square brackets next to our call manager cdr analysis reporting link to act as soon be purged after a spreadsheet. If a static or thread-local (since C++11) variable is constant-initialized (see below), constant initialization is performed instead of zero initialization before all other initializations..
