C++ 根据字符串 调用同名函数

根据字符串，调用与字符串同名函数：

#include <map>#include <string>#include <iostream>typedef void (*pFunc)();std::map<std::string, pFunc> strFuncMap;void func1(){printf("this is func1!\n");}void func2(){printf("this is func2!\n");}void buildMap(){ strFuncMap["func1"] = &func1; strFuncMap["func2"] = &func2;}void callFunc(const std::string& str) { if(strFuncMap.count(str))(*strFuncMap[str])();elsestd::cout << "unsupported function str : " << str.c_str() << "\n" << std::endl;}int main(){buildMap();//begin call funccallFunc("func1");callFunc("func2");callFunc("func3");system("pause");return 0;}

输出结果：

this is func1!
this is func2!
unsupported function str : func3
