Code reuse is an important goal of modern program design, and the template is effective in software reuse. Templates and exception handling are important mechanisms of C + +. The use of templates can greatly shorten the length of the

Define a character array:Char carray[] = {' I ', ' a ', ' m ', ' a ', ' m ', ' a ', ' n ', ' mm '};Use ' \ s ' to represent the end of the character array flag. It does not account for the character length, but is the size of the

Union is an unnoticed keyword, and it does not appear in C + + for the sake of inheriting the C language. Its role is mainly to save memory space, in embedded programming is useful. But in C + +, which is designed for contemporary microcomputers, it

Grey: Perhaps it is the fate of this, the end of the senior year in I think I have a strong interest in physics when I was resolutely a black and white bear pit to the software of this profession.Black: First contact with C + +, it really does not

Transfer from Chenhao's blogObjectiveIn talking about the virtual function table, at least the following are not involved:-The case of a member variable.-There is a case of duplicate inheritance.-There is a case of virtual inheritance.-There is a

C + + language standards These years have evolved quickly, and many of the newly introduced features have not been used. To be honest, I am also lazy, always feel that I have mastered the C + + has enough to deal with the daily projects, so there is

The problem solved: Use the prototype instance to specify the kind of object to create and create a new object by copying the prototypes.This is in fact the role of the copy constructor of C + + is consistent, in fact, the dynamic extraction of the
