For many years, many programming languages and tools have included support for regular expressions. NET base Class library contains a namespace and a series of classes that can give full play to the power of regular expressions, and they are all

Array C + + does not support an abstract abstraction of arrays nor does it support operations on an entire array we sometimes want to manipulate the entire array, such as assigning an array to another array for equal comparison of two arrays or to

Some programs can be difficult to grasp when debugging breakpoints (such as service programs), some programs need to cycle countless times, to see the results of each or every time, and so on. Let's write a simple log program, TXT file generated in

One, what is the socket A socket, a socket, used to describe an address and a port, is a handle to a communication chain. The application sends a request or response to the network via the socket. Sockets (socket) programming there are three kinds,

A pointer is a special variable that is stored in a value that is interpreted as an address in memory. To figure out a pointer needs to figure out four aspects of the pointer: the type of the pointer, the type the pointer is pointing to, the value
