For example, suppose we assign an integer value to a floating-point variable, and the computer automatically converts the int to float. By styling, we can explicitly set this type of conversion, or force it to proceed when it is not normally possible.To make a styling, place the desired data type (including all modifiers) in pare

This article from: http://blog.csdn.net/xuejianwu/article/details/6931926X. Conversion operatorsConversion operators are used to implement the ability to convert the type of an input object into a sequence. The conversion method whose name starts with "as" changes the static type of the source collection but does not enumerate (lazy-load) this source collection. The method that begins with the name "to" enumerates the source collection and puts the items into the appropriate collection type.1. A

hand. If downcast and the type parameter is not polymorphic, dynamic_cast cannot be used and the compiler will give an error.dynamic_cast returns a null pointer if the type of the object is not the base class of the type that will be converted to. That is, a non-derived class object is converted to a base class object, or a base class object is converted to a derived class object, returning a null pointer.#include In this example, the base class object is converted to a derived class object and
