void TestFunPtr();
~Test();
protected:
// 注意此處聲明使用Test::*fun_ptr
void Fun(int (Test::*fun_ptr)(int, int));
int Handler(int a, int b);
};
Test.cpp

/// 注意此處調(diào)用

}
void Test::Fun(int (Test::*fun_ptr)(int, int))
{
// 注意this->*fun_ptr 不知道為什么要這么指向场梆，估計(jì)和c++編譯相關(guān)
(this->*fun_ptr)(3, 4);
}
int Test::Handler(int a, int b)
{
printf("%d, %d\n",a, b);
return 1;
