What is this weird colon-member (" : ") syntax in the constructor?

Foo(int num): bar(num) In C++, this is known as a Member Initializer List. Simply put, it sets the value of your member bar to num. There is a significant difference between initializing a member with the Member initializer list and assigning a value to it within the function Object() { [native code] } body. When you use the Member initializer list to initialise fields, the constructors are only called once, and the object is constructed and initialised in a single operation. If you use assignment, the fields will be initialised with default constructors and then reassigned with actual values (via the assignment operator). As you can see, there is an extra overhead of creation and assignment in the latter, which may be significant for user defined classes. Cost of Member Initialization =Object ...READ MORE

What is the best way to use a HashMap in C++?

The ordered and unordered map containers (std::map and std::unordered map) are included in the standard library.  The items in an ordered map are sorted by key, and insert and access are in O (log n).  For ordered maps, the standard library often use red black trees.  However, this is only an implementation detail.  Insert and access are in O in an unordered map (1).  It is simply another term for a hashtable. An illustration using (ordered) std::map: #include <map> #include <iostream> #include <cassert> int main(int argc, char ...READ MORE
