函数签名的概念 函数签名主要包括1、函数名；2、参数列表（参数的个数、数据类型和顺序）；但是注意，C++官方定义中函数签名不包括返回值！！ 1、重载 函数重载是指在同一作用域内，可以有一组具有相同函数名，不同参数列表的函数，这组函数被称为重载函数，与函数返回类型无关。重载要求参数列表必须不同，比如参 阅读全文

摘要： 1. 面向对象程序设计的核心思想是数据抽象、继承和动态绑定。数据抽象将类的接口和实现分离；继承定义相似的类型并对齐相似关系建模；动态绑定，在一定程度上忽略相似类型的区别，而以统一的方式使用它们的对象。 2. 派生类列表中每个基类前面可以有访问说明符；派生类必须在其内部对所有重新定义的虚函数进 阅读全文
