如何用程序来完成以下的 定义结构体和赋值

怎么用程序来完成以下的 定义结构体和赋值
参数是num
N=unm
struct MacID_Struct MacS[MacNum]={{0x01,"50"},{0x02,"60"},{0x03,"46"},{0x04,"52"},{0x05,"58"},{0x06,"46"},{0x07,"40"},{0x08,"49"}……",{0x0N,"46"}};//三个机器的001，臂长50米；002，臂长60m，003，臂长50m


------解决方案--------------------
struct MacID_Struct
{
unsigned char num;
unsigned char strnum[3];
}
------解决方案--------------------
多个的话就可以定义成 struct MacID_Struct的数组了。

------解决方案--------------------

探讨

struct MacID_Struct
{
unsigned char num;
unsigned char strnum[3];
}

------解决方案--------------------
struct MacID_Struct a[SIZE] = {{0x01,"50"},{0x02,"60"},{0x03,"46"},{0x04,"52"},{0x05,"58"},{0x06,"46"},{0x07,"40"},{0x08,"49"}……",{0x0N,"46"}};

结构数组
------解决方案--------------------
似乎要动态申请内存
那个怎么写来着,macall?
