In c programming language, variable can be initialized in the declaration statement of any block (either it may main’s block or any other function’s block). While declaring a variable you can provide a value t
// We use the second byte of the guard variable to remember that we’re // in the middle of an initialization. class recursive_init: public std::exception { public: recursive_init() throw() { } virtual ~recursive_init() throw (); }; recursive_init::~recursive_init() throw() { }...

Learn about class types, how to use classes, and how to create new class type declarations for your app.
The initialization for each variable must be enclosed in braces. For related information, see class, union, and enum. Example Copy // struct1.cpp struct PERSON { // Declare PERSON struct type int age; // Declare member types long ss; float weight; char name[25]; } family_member; //...
在《Objective C类方法load和initialize的区别》一文中,我介绍了Objective-C对待+(void)initialize和+(void)load两个方法在编译和执行时出现的不同。而这些不同也是在使用时应该非常注意的地方。不过文章里面我没有讲这两个方法在Objective-C中究竟有什么实用价值。
