Calling Derived class functions using base class object Can a struct contain an array of unknown size until runtime? Can I call a .NET dll from unmanaged C++ Or Delphi code without registering the .NET COM object Can I Load Animated Gif into Dialog Box for MFC Application? Can I target ...
1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...

Vector常用函数 size()/empty() size()函数返回vector的实际长度(包含的元素个数),empty()函数返回一个bool值,表明vector是否为空.二者的时间复杂度都为O(1). 所有的STL容器都支持这两个方法,还以也相同,之后我们就不再重复. clear() clear()函数把vector清空 ...

class Object { public: Object() = default; // ... }; void fun() { Object obj; // do sth } 在上述代码中,obj就是在栈上进行分配,当出了fun作用域的时候,会自动调用Object的析构函数对其进行释放。 前面有提到,局部变量会在作用域(如函数作用域、块作用域等)结束后析构、释放内存。因为分配和释...
