1== sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <= sizeof(longlong) 由于历史原因,整型的位宽有多种标准: 为解决这一问题,C99/C++11引入了定宽整数类型。 定宽整数类型 定宽整数类型本质上是普通整数类型的类型别名。 <cstdint>提供了若干定宽整数的类型和各定宽整数类型

Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for ...
