Usage reinterpret_cast type conversion expression: as the declaration of the expression

Defined in header <regex> The regular expressions library provides a class that represents regular expressions, which are a kind of mini-language used to perform pattern matching within strings. Almost all operations with regexes can be characterized by operating on several of the following objects: Target sequence. The character sequence that is searched for a pattern. This may be a range specified by two iterators, a null-terminated character string or std::string. Pattern. This

Defined in header <cstdlib> #define RAND_MAX /*implementation defined*/ Expands to an integer constant expression equal to the maximum value returned by the function std::rand. This value is implementation dependent. It's guaranteed that this value is at least 32767.

A RandomNumberDistribution is a function object returning random numbers according to a probability density function p(x) or a discrete probability distribution P(xi). Requirements D is a class meeting the RandomNumberDistribution requirements. It shall also satisfy the CopyConstructible and CopyAssignable requirements. T is the associated result_type. P is the associated param_type. It shall satisfy the CopyConstructible, CopyAssignable, and EqualityComparable requirements. It also h
