class Myadd { public: int operator()(int v1, int v2) { return v1 + v2; } }; void test01() { Myadd myadd; cout << myadd(10, 10) << endl; } 函数对象超出普通函数的概念,函数对象可以有自己的状态 class Myadd { public: Myadd() { this->count = 0; } int operator()(int v1,...
从实现角度来看,仿函数是一种重载了operator()的class 或者class template适配器:一种用来修饰容器或者仿函数或迭代器接口的东西。空间配置器:负责空间的配置与管理。从实现角度看,配置器是一个实现了动态空间配置、空间管理、空间释放的class tempalte.STL六大组件的交互关系,容器通过空间配置器取得数据存储空间,算法通过...

Please note that the actual memory sizes and ranges can vary depending on the specific compiler and system architecture (32-bit vs. 64-bit). You can use thesizeofoperator in C to determine the size of data types on your system, as shown in the previous answer. ...
