比较适用于大量参数的数组，下标获取值（提升代码效率）

两个头文件：

List.h :

//List.h"aaa","bbb","ccc",

List2.h

//List2.haaa,bbb,ccc,

初始化enum:

#ifndef TTT_H_#define TTT_H_enum {#include "List2.h"    NR_OF_OBJECT_COMMANDS};#endif /* TTT_H_ */

main.c:

#include 
     
      #include "ttt.h"char *objectMnemonic[] = {#include "List.h"};int main(){    printf("aaa = %d\n",aaa);  // 枚举    printf("NR_OF_OBJECT_COMMANDS = %d\n",NR_OF_OBJECT_COMMANDS); // 枚举    printf("objectMnemonic = %s\n",objectMnemonic[1]);   // 字符串数组下标 获取 字符串 　　 printf("objectMnemonic = %s\n",objectMnemonic[aaa]);  // 下标是枚举，获取对应字符串，这才是核心                                                          // 还可以应用到多个字符串和对应的值（类似c++的map），比如obj[one] = 1；（这个数组可以手动初始化） return 0;}
     

 gcc 版本 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)

Console:

aaa = 0

NR_OF_OBJECT_COMMANDS = 3

objectMnemonic = bbb

objectMnemonic = aaa              

疑问１：我把List.h 重命名为List.c   头文件也包含改为List.c 

不知道为什么报错：

gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"List.d" -MT"List.d" -o "List.o" "../List.c"

../List.c:2:1: error: expected identifier or ‘(’ before string constant

"aaa",

^

make: *** [List.o] Error 1

疑问２: List2.h 改为　List2.c  也会报错，不知道为什么。

如下：

gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"List2.d" -MT"List2.d" -o "List2.o" "../List2.c"

../List2.c:2:1: warning: data definition has no type or storage class [enabled by default]

aaa,

^

../List2.c:2:1: warning: type defaults to ‘int’ in declaration of ‘aaa’ [-Wimplicit-int]

../List2.c:3:1: warning: type defaults to ‘int’ in declaration of ‘bbb’ [-Wimplicit-int]

bbb,

^

../List2.c:4:1: warning: type defaults to ‘int’ in declaration of ‘ccc’ [-Wimplicit-int]

ccc,

^

../List2.c:4:1: error: expected identifier or ‘(’ at end of input

make: *** [List2.o] Error 1
