Socket programming: byte and socket byte When it comes to socket programming, it will certainly be subject to byte sequence conversion. For a string, there is no difference in the byte order. Just like writing, the memory is like paper, and the

Tail recursion = recursion + iteration ?, Tail recursion0 Introduction It usually involves recursion and iteration. recursion is intuitive, but it occupies too much memory and time. iteration is fast, but it is not as concise and clear as recursive

Create a window prompt in C language, a window in C Language Open Vs2012 [my account is 2012] /* X is useless... If you do not change the value of 2013 or 2015, devC ++ and the original vc6.0 are also supported.   If the compiling environment

C language: the day of a year, month, or year Looking at this title, it is actually quite simple to implement this function. You can easily implement this function by using the switch statement in C language with the condition of a leap year or a

C random number, random number   This is a bit of a pitfall. The results are the same every time, so good random is not random. In fact, the random number itself is also calculated, and each time it is calculated by the random number seed. If the

Basic linked list operations in C Language The importance of linked lists in data structures and algorithms is self-evident. Here we use C to implement basic operations in the Linked List (single-chain table. For the basic concepts of the linked

Simulate the virtual function table of C ++ in pure C Language Polymorphism, interface-oriented programming, and other design methods are not bound to any specific language. Pure C can also be used to implement simple polymorphism. The following is
