类型转换(Type Casting) 类型转换就是将给定类型的表达式转换为另一种类型。C++中的转型可分为两种:隐式类型转换和显式类型转换。下面将详细介绍这两种转型操作,以及各自的适用场景,潜在问题,最终将总结使用类型转换操作应牢记的原则。 一,隐式类型转换 隐式类型转换是C中的遗留物,在C++中并不推荐使用(C++有专门的转型操作符,见下文的显式转

Converting data types from one to another is a most basic aspect for any programmers. First, let us start with the basics. int nNumber; The following are few things to keep in mind for the above line of code: Data type of nNumber is int, which means that
In C++, there are four main type-casting operators; static_cast, dynamic_cast, const_cast, and reinterpret_cast. In this tutorial, you will learn about C++ type conversion operators with the help of examples
C++中的类型擦除(type erasure in c++) 原载:www.cnblogs.com/liyiwen 关于类型擦除,在网上搜出来的中文资料比较少,而且一提到类型擦除,检索结果里就跑出很多 Java 和 C# 相关的文章来(它们实现“泛型”的方式)。所以,这一篇我打算写得稍微详细一点。 注意,这是一篇读书笔记(《C++ template metaprogramming》...
