Course Introduction:Go框架通过内存池分配机制和分代垃圾回收算法管理内存:内存分配:使用arena内存池分配内存。垃圾回收:使用分代算法,将内存划分为新生代、旧生代和老生代,定期回收不再使用的内存。配置:可通过环境变量控制垃圾收集激进性(GOGC)和限制同时运行的垃圾收集器数量(GOMAXPROCS)。

Course Introduction:C++不支持垃圾回收,因为它会带来性能开销、缺乏实时确定性以及对内存控制的细粒度不足等问题。为了管理内存,C++程序员必须手动分配和释放内存,避免内存泄漏,并且可以使用智能指针来简化内存管理。

Course Introduction:垃圾回收是一种自动释放不再使用的内存的技术,垃圾收集器会定期扫描并释放悬垂对象。智能指针是C++类,可自动管理所指向对象的内存,跟踪引用计数并在不再引用时释放内存。
