static char array: times - 10000 memory - 1740k VM - 820k
char* array: times - 10000 memory - 2292k VM - 1368k
string vector: times - 10000 memory - 1752k VM - 828k
char* vector: times - 10000 memory - 2340k VM - 1420k

可以看出，使用string以及vector或者静态分配数组，内存消耗是比较少的，多次new小内存导致内存消耗明显增多。  阅读全文

为什么会存在这么多错误认识？原因主要有三个，一是C++语言的细节太多。二是一些著名的C++书籍总在（不管有意还是无意）暗示语言细节的重要性和有趣。三是现代C++库的开发哲学必须用到一些犄角旮旯的语言细节（但注意，是库设计，不是日常编程）。这些共同塑造了C++社群的整体心态和哲学。  阅读全文

在C++中，当子类改写/重定义（override/redefine）了在父类中定义了的函数时，关键字virtual使得该函数具有了多态性，但是 virtual关键字也并不是必不可少的（只要在父类中被定义一次就行了）。编译器通过产生动态分配（dynamic dispatch）的方式来实现真正的多态函数调用。  阅读全文
