原文:Exception Handling in C++ - GeeksforGeeks C++ 相较于 C 的一大改进就是增加了异常处理机制。“异常”指程序在执行过程中出现非正常表现的情况。异常可以分为两大类:同步的和异步的(异步异常是在程序控制的范围之外的,比如磁盘读取错误、键盘中断等)。C++ 为异常提供了下面几种关键字: try:表示能够抛出异...
原文连接:geeksforgeeks.org/imple 想要实现单例类,需要综合使用一些面向对象编程中的核心概念——访问控制符、构造函数、静态方法等。 在C++ 中实现单例类的步骤 将类中所有的构造函数设为 private; 删除类的拷贝构造函数; 定义一个 private 的 static 指针,指向当前单例类本身; 定义一个 public 的静态函数,其...
