本文主要介绍 map容器中如何放入函数指针和类成员函数指针。
一、map容器的使用：
// 定义一个map对象map<int, string> mapStudent;参考：/sevenjoin/article/details/81943864
二、map容器与普通函数指针
#include "map"#include "string"#include "vector"#include "iostream"void Func1(int a){std::cout <<"func1: "<< a<<std::endl;}void Func2(int a){std::cout <<"func2: "<< a<<std::endl;}void Func3(int a){std::cout <<"func3: "<< a<<std::endl;}int main(int argc, char** argv){std::map<std::string, void(*)(int)> Func = {{"name1", Func1},{"name2", Func2},{"name3", Func3}};Func["name2"](5); return 0;}
三、map容器与类成员函数指针
#include "map"#include "string"#include "vector"#include "iostream"class TestPointer{public:TestPointer() = default;~TestPointer() = default;void Run(){(this->*func_map["name2"])(5);}private:void Test1(int a){std::cout<<"test1: "<<a<<std::endl;}void Test2(int a){std::cout<<"test2: "<<a<<std::endl;}private:typedef void(TestPointer::*pTest)(int);std::map<std::string, pTest> func_map = {{"name1", &TestPointer::Test1},{"name2", &TestPointer::Test2}};};int main(int argc, char** argv){TestPointer test;test.Run();return 0;}
