Initially read data structure books did not carefully read the hash, the subconscious thought too difficult, should not be used to it ~ but, the recent focus on the hash table is I brush leedcode, the problem two sum can be solved by hash table,

First, the foreword: In the process of preparing for the soft test, the prototype model was involved, which mentioned that in the process of shallow copying, the value type and reference type are different. So what exactly is a value type and what

This period of time rather depressed, feel the process of doing this line is too boring, and seems to be less and less life circle. Simply to write something about some of the items that have been touched on before, is to do a summary and memorial.

Conversion between value types and reference types is also known as a boxed unboxing operation. Converting a base type or value type to a reference type is called boxing, Changes a value type to a reference type. The meaning of the specific code

This two days simply looked at the next C + + socket communication, said socket communication, we have to mention the TCP/IP protocol, this agreement is famous, I want to see the programming at least heard. In the TCP/IP protocol, the most common is

So far, we've been using traditional type conversions for simple object type conversions. For example, to convert a floating-point number of type double to an integer number int, we do this: int i;Double D;i = (int) d; or i = int (d); This is fine
