如何获取结构体成员名称

假如有结构体
struct msg{
char arr[8];
int tmp;
};
如何获取meg中的成员名称arr

Answer 1

要实现程序运行时得到结构体的变量名字，可以参考MFC中的实现方法。用宏函数来处理了。。如下测试代码：
#include <<a href="https://www.baidu.com/s?wd=stdio.h&tn=44039180_cpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1YdPHwBrHwWuWwBPhP9PWnk0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EPHR1P10sn1b4P1T4nHTzrHTz" target="_blank" class="baidu-highlight">stdio.h</a>>struct man {char name[20];int age, sex;};#define PRINT_STURCT(s_name, e_name) \printf("%s.%s\n", #s_name, #e_name) \int main(){PRINT_STURCT(man, name);PRINT_STURCT(man, age);PRINT_STURCT(nam ,sex);return 0;}
