You can use the keywords class and struct in forward declarations interchangeably. For example: class X; // fwd declaration uses ‘class’X *p;struct X // definition uses ‘struct'{};void f(){ p=new X;}
Many symbolic debuggers limit the length of symbols they can display. For example, the Visual C++ debugger can display strings that contain up to 255 characters. Suppose you have a
Suppose you need to define a function that takes a vector object and performs certain operations on it. The function has to be generic, that is, it should handle all
Sometimes you need to make sure that only one instance of the same application can run at any given time. Although every platform defines different locking schemes, you can use
One of the issues that have been discussed at the C++ standards committee is whether the declaration of static member functions is permitted. For example: struct A{ extern
To simplify the process of writing custom function objects, the Standard Library provides two classes that serve as base classes of such objects: std::unary_function and std::binary_function. Both are declared in
The remove_if() algorithms (defined in the standard header ) has the following prototype: template ForwardIterator remove (ForwardIterator first, ForwardIterator last, Predicate pred); The first two arguments mark the sequence’s beginning
The Standard Library defines the std::remove() algorithm, which moves desired elements to the front of a container and returns an iterator pointing to the end of the sequence of the
