c 基础系列 define struct and init struct array

1. struct defination

    struct  _name

　{

         int a;

        char*ｂ;

　　...

    }

　一般之后还要typedef it to let its use be convenient, for example:

    typedef struct _name name;

   or directly write:

   typedef strunct _name

   {

         int a;

        char*ｂ;

　　...　　

   }name;

2. initialization

    name x={3,"char",...};

3. initialize an array of struct:

   name arr[]={

　　　　　　　　{1,"xy",...},

　　　　　　　　{2,"ab",...},

　　　　　　　　...

                       };

The code fragment below demonstrates how to initialize an array of structures within a Microsoft C program. Each element is grouped within brackets, and the elements are separated by commas. The initialization of the array rgttype shows how to initialize a structure within a structure within an array of structures.

/* Compile options needed:  none
*/ 

struct stype {
   int a;
   int b;
   int c;
};

struct ttype {
   int alpha;
   struct stype beta;
};

                        /*   a,    b,   c  */ 
struct stype rgstype[2] = { {8,   9,   10}, \ 
                            {15,  16,  17} };

                        /*  alpha     beta     */ 
struct ttype rgttype[2] = { {{1},   {2,3,4}}, \ 
                            {{5},   {6,7,8}}  };
