Recently read the idea of C + + programming, see the 13th chapter of dynamic memory management when the time to go around, mainly in the data and pointers this piece confused. Now summarize some of the information found below:1. Arrays are arrays,

In the C + + class that talks about static, we can define static members, static member functions in the Class! C++primer: Static members It is not like ordinary data members, static data members exist independent of any object of the class, and

Earlier, C + + inherited and extended the traditional type conversion of C language, and finally left some on the pointer and reference on the transformation problem, did not do in detail to tell. C++compared to C is an object-oriented language, one

In C and Java, there is an entry function or method for a program, that is, the main function or the main method. In JavaScript, the program runs from the head of the JS source file. But in a sense, we can still invent a main function as the

Regular expression syntaxA regular expression describes the constituent rules (patterns) of a string. If a specific string exactly conforms to the rule described by the regular expression, the string is matched to the expression. Let's take a look
