当你在C++中遇到 'unordered_map' was not declared in this scope 的错误时,这通常意味着编译器在当前的上下文中无法识别 unordered_map 类型。这个问题可以通过以下几个步骤来解决: 检查是否包含了正确的头文件: unordered_map 是定义在 <unordered_map> 头文件中的,确保你的代码中包含了这个头文件。示...
Define and use the "private" container in the c-file:// Dataset.c #include "Dataset.h" #include "Point.h" // Point must be defined here. #define i_is_forward // flag that the container was forward declared. #define i_type PointVec #define i_val struct Point #include "stc/vec.h...
You may specify a set of "standard" template parameters for each container, but as a minimumonly one is required:i_key(+i_valfor maps). In this case, STC assumes that the elements are of basic types. For non-trivial types, additional template parameters must be given. Alternative insert/...
