For the server, the communication process is as follows: 1,call socket Function create listener socket 2,call bind Function will socket Bind to a IP And port nu ...

preface In the last article ndnSIM learning (8) -- ndn-simple.cpp of examples analyzes each function line by line In, we analyze the underlying principle of the whole ndn-simple.cpp. As the core, it is naturally the working process of the whole network: how do consumers send interest packets? How do producers return packets based on intere ...

1. When to mix c and c + + code? Here are some key points: 1. When compiling main(), you must use the C + + compiler (for example, for static initialization)2. Your C + + compiler should guide the linking process (for example, so that it can get its special library)3. Your C and C + + compilers may need to be from the same vendor and have com ...

Pointers and arrays A pointer is a variable that holds the address of a variable. Pointers are often the only way to express a computer, Using pointers usually produces more efficient and compact code.

Sequence table *** * this paper mainly talks about one kind of linear table, that is, sequential table. Sequential table is to use sequential storage to store data. The so-called sequential storage means that the address of data in memory is also stored continuously, and there is no space (interval) in the middle. The advantage of sequential t ...
