An inline function in C++ is a special function that reduces call overhead. It signals the compiler to expand the function code in-line where it is called.
friend:友元函数,在C++中友元函数允许在类外访问该类中的任何成员,就象成员函数一样,友元函数用关键字friend说明。 1. 友元函数不是类的成员函数。 2. 友元函数可以通过对象访问所有成员,私有和保护成员也一样。 class Date { friend void Display( const Date & d); private : int _year ; // 年 int _m...
When the postfix-expression in a function call (5.2.2) is an unqualified-id, other namespaces not considered during the usual unqualified lookup (3.4.1) may be searched, and in those namespaces, namespace-scope friend function declarations (11.3) not otherwise visible may be found. These modif...

attempting to inline a recursive function) the compiler will fail to terminate. If done over-enthusiastically the code size may increase exponentially, e.g. if function f calls g twice, and g calls h twice and h is inlined in g which is inlined in f (in either order) then there will...
Theinlinespecifier, when used in a function'sdecl-specifier-seq, declares the function to be aninline function. A function defined entirely inside aclass/struct/union definition, whether it's a member function or a non-memberfriendfunction, is implicitly an inline functionunless it is attached ...
others do not. No matter how you designate a function as inline, it is a request that ... Is there another way to tell the compiler to make a member function inline?: Yep: define the member function in the class body itself: ... This is often ...
friend函数&inline函数 友元函数 类的友元函数是定义在类外部,但有权访问类的所有私有(private)成员和保护(protected)成员。尽管友元函数的原型有在类的定义中出现过,但是友元函数并不是成员函数。 友元可以是一个函数,该函数被称为友元函数;友元也可以是一个类,该类被称为友元类,在这种情况下,整个类及其所有成员...
