若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : Vec
Base b;b.who();// 此处的虚函数是通过指针调用的,呈现多态性,需要在运行时期间才能确定,所以不能为内联。Base*ptr=newDerived();ptr->who();// 因为Base有虚析构函数(virtual ~Base() {}),所以 delete 时,会先调用派生类(Derived)析构函数,再调用基类(Base)析构函数,防止内存泄漏。deleteptr;ptr=nul...
