方法前面的 +/- 号代表函数的类型:加号(+)代表类方法(class method),不需要实例就可以调用,与C++ 的静态函数(static member function)相似。减号(-)即是一般的实例方法(instance method)。 这里提供了一份意义相近的C++语法对照,如下: classMyObject:publicNSObject{protected:intmemberVar1;// 实体变量void*membe...

In the following code, the main() function has an array of integers. A user−defined function average () is called by passing the array to it. The average() function receives the array, and adds its elements using a for loop. It returns a float value representing the average of ...
This method posts a WM_COMMAND message to the window that owns the toolbar by calling CWnd::PostMessage and passing the command ID of the specified button as the wParam parameter. Use the ON_COMMAND macro to map the WM_COMMAND message to a member function. CMFCToolBar::RemoveAllButtons Re...
内存管理是 C++最令人切齿痛恨的问题,也是C++最有争议的问题,C++高手从中获得了更好的性能,更大的自由,C++菜鸟的收获则是一遍一遍的检查代码和对 C++的痛恨,但内存管理在C++中无处不在,内存泄漏几乎在每个C++程序中都会发生,因此要想成为C++高手,内存管理一关是必须要过的,除非放弃 C++,转到Java或者.NET,他们的...
Your Decode function as an example has a reference to a class type as the function declaration in the class definition. But you start off the function definition with a pointer to a basic type.In order to match function declarations to the function body, the compiler will match the ...

Just like variables, array can also be passed to a function as an argument . In this guide, we will learn how to pass the array to a function using call by value and call by reference methods. To understand this guide, you should have the knowledge of fo
