但现在 MacOS (clang++ 12), Ubuntu16 (g++ 5.4), Windows (mingw 9.2) 上测试,这段代码都没有问题,并且能输出正确结果。编译选项为: g++test.cpp -std=c++11-O0 实际上也不难理解,因为是连续内存,i指向的内存位置,在erase之后被其他数据覆盖了(这里的行为就跟我们使用普通数组一样),但该位置仍然在vector...

Parts of that library were standardized in the C++ Standard Library, along with the ISO C runtime library, parts of the Boost library, and other functionality. Sometimes "STL" is used to refer to the containers and algorithms parts of the C++ Standard Library adapted from Stepanov's STL. ...
* <cmath>’s binary overloads weren’t constrained like the unary overloads, resulting in compiler errors in obscure cases (DevDiv#577433/Connect#776471). Although the Standard doesn’t require this to work, we’ve constrained the binary overloads so it works. ...
queue是一种先进先出(First In First Out,FIFO)的数据结构。它有两个出口,形式如下图所示 特点: queue允许新增元素、移除元素、从最底端加入元素、取得最顶端元素 但除了最底端可以加入、最顶端可以取出外,没有任何其他方法可以存取queue的其他元素。换言之queue不允许有遍历行为 将元素推入queue的动作称为push,将...
