关于C++ STL vector 中的sort排序算法有三种自定义实现,它们本质上都是返回bool类型,提供给sort函数作为第三个参数。 重载运算符 全局的比较函数 函数对象 我认为从实现方式看,重载运算符和函数对象实现本质上是一样的:两者都是括号运算符的重载。 重载运算符利用了泛型模板,先重载模板中的括号运算符,接着重载里...

what(): vector::_M_range_check: __n (which is 0) >= this->size() (which is 0) 一开始我以为是这个同学的代码问题,没考虑到一些边界情况,导致越界。后来自己测试下,发现确实是std::sort问题,但是自己写了几个简单的demo,std::sort函数又表现正常,令人匪夷所思。
