A common gap usually appears in a trading range or congestion area, and reinforces the apparent lack of interest in the stock at that time. Many times this is further exacerbated by low trading volume. Being aware of these types of gaps is good, but doubtful that they will produce a trading opportunities.
Conversion functions (C++ only) You can define a member function of a class, called a conversion function, that converts from the type of its class to another specified type.
In computer programming, a function prototype or function interface is a declaration of a function that specifies the function's name and type signature (arity, parameter types, and return type), but omits the function body. The term is particularly used in C, C++ , and PHP. While a function definition specifies how the function does what it does (the implementation), a function prototype merely specifies its interface, i.e. what data types go in and come out of it.
