1、序列式容器(Sequence container),这是一种有序的集合,其内每个元素均有确凿的位置——取决于插入时机和地点,与元素值无关。array、 vector、 deque、 list、 forward_list 2、关联式容器(Associative container),这是一种已排序(sorted)集合,元素位置取决于其value(或key——如果元素是个key/value pair)和给定...
在名为cname的头文件中定义的名字从属于命名空间std,而定义在名为.h的文件中的则不然。 vector 标准库类型vector表示对象的集合,其中所有的对象的类型都相同。 vector定义在命名空间std中。 vector是一个类模板。模板本身不是类或函数,编译器根据模板创建类或函数的过程称为实例化(instantiation),当使用模板时,需要...
vectormyVector; myVector.push_back(99); return0; } 如果有人试图在同时使用std::vector的项目中使用这个类,他们会得到一个错误“error C2872: ‘vector’: ambiguous symbol”。这是因为编译器无法决定客户端代码引用的向量是std::vector还是location.h中定义的vector对象。 如何解决这个问题? 始终将API放在自...

1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...

bool operator==(const MyAlloc& other) const const elements The C++ standard has always forbidden containers of const elements (such as vector<const T> or set<const T>). Visual Studio 2013 and earlier accepted such containers. In the current version, such containers fail to compile. std::...
