用字符串调用同名的函数[转]

str.def :
my_Macro(func1)my_Macro(func2)

str.h :
#pragma oncevoid func1();void func2();#define my_Macro(a) atypedef void (*func)();func fArray[] ={#include "str.def"};#undef my_Macro#define my_Macro(a) # achar* str[] ={#include "str.def"};

str.cpp :

#include "str.h"#include "string.h"void func1(){};void func2(){}void main();{char call[] = "func1";int len = sizeof(fArray) / sizeof(fArray[0]);for(int i = 0; i < len; i++){if(strcmp(str[i], call) == 0){fArray[i]();break;}}}
