C 如何创建结构数组的数组

我正在尝试使用结构数组的数组创建一个符号表

现在我有一个结构数组，它是这样创建的：

#define MAXSIZE 20 /* maximum number of symbols */
#define MAXSCOPE 10 /* maximum number of scope levels */

 struct tableEntry {
 char *name;
 char *args;
 int value;
 int scope;
 char *type;
 int used;
 } tableEntry [MAXSIZE];

symbolTable[MAXSCOPE].tableEntry[MAXSIZE]

// Initialise 'value' in each entry to 2
int scope=0;
int size=0;
for (; scope < MAXSCOPE; scope++)
{
    for (; size < MAXSIZE; size++)
    {
        myArray[scope][size].value = 2;
    }
}

这是可行的，但我想做这样的事情：

#define MAXSIZE 20 /* maximum number of symbols */
#define MAXSCOPE 10 /* maximum number of scope levels */

 struct tableEntry {
 char *name;
 char *args;
 int value;
 int scope;
 char *type;
 int used;
 } tableEntry [MAXSIZE];

symbolTable[MAXSCOPE].tableEntry[MAXSIZE]

// Initialise 'value' in each entry to 2
int scope=0;
int size=0;
for (; scope < MAXSCOPE; scope++)
{
    for (; size < MAXSIZE; size++)
    {
        myArray[scope][size].value = 2;
    }
}

我该怎么做？我想做的有意义吗？

创建一个二维结构数组：

// Define the type
typedef struct tableEntry {
    char *name;
    char *args;
    int value;
    int scope;
    char *type;
    int used;
} tableEntry;

// Instantiate a 2D array of this type
tableEntry myArray[MAXSCOPE][MAXSIZE];

您现在可以访问如下单个条目：

#define MAXSIZE 20 /* maximum number of symbols */
#define MAXSCOPE 10 /* maximum number of scope levels */

 struct tableEntry {
 char *name;
 char *args;
 int value;
 int scope;
 char *type;
 int used;
 } tableEntry [MAXSIZE];

symbolTable[MAXSCOPE].tableEntry[MAXSIZE]

// Initialise 'value' in each entry to 2
int scope=0;
int size=0;
for (; scope < MAXSCOPE; scope++)
{
    for (; size < MAXSIZE; size++)
    {
        myArray[scope][size].value = 2;
    }
}

//将每个条目中的“value”初始化为2
int scope=0；
int size=0；
用于（；范围

并使用例如

symbolTable[scope][entry].value;

如果你真的想通过这种方式访问它

#define MAXSIZE 20 /* maximum number of symbols */
#define MAXSCOPE 10 /* maximum number of scope levels */

 struct _table_entry_ {
     char *name;
     char *args;
     int value;
     int scope;
     char *type;
     int used;
};

struct _symbol_table_ {
    _table_entry_ tableEntry[MAXSIZE]; 
}symbolTable[MAXSCOPE];

这是您访问数据的方式

symbolTable[1].tableEntry[2].value = 1;
