C++完全删除(或重置)结构的所有值？

Question

所以，我只是想知道我们如何才能完全删除或重置结构以便重复使用？

我刚刚输入了这个，给你:

typedef struct PART_STRUCT
{
    unsigned int Id;
    std::string Label;
} Part;

typedef struct OBJECT_STRUCT
{
    std::vector< unsigned char > DBA;
    std::vector< Part > Parts;
    unsigned int Id;
} Object;

Object Engine;

// Initialize all members of Engine
// Do whatever with Engine
// ...
// Erase/Reset Engine value

Answer 1

你可以给它分配一个临时构造的:

Part my_struct;

my_struct = Part(); // reset

C++11:

my_struct = {}; // reset
