The algorithm of factorial is more than two aspects: first, high precision computation and the second is related to number theory. First, the high precision calculation factorial This is actually the least technical content of the problem, but

The pointer is a more headache-prone problem in C/A + + learning, and in the process of programming, pointers are often the cause of hidden bugs. Here to talk about the application of pointers and need to pay attention to some of the problems, which

1. C + + as a new language learning (and C does not matter!); 2. See "Thinking in C + +", do not see "C + + Become die die" (C + + programming ideas, translation is very poor); 3. See "The C + + programming Language" (this thing has a photocopy

1. The need for friend functions and friend classes:The class has encapsulation and information hiding attributes.Only member functions of a class can access private members of a class, and other functions in the program cannot access private

Each class has only one destructor and one assignment function, but it can have multiple constructors (one copy constructor, others called ordinary constructors). For any class A, if you do not write the above functions, the C + + compiler will
