Header files: #include Define function: char * strtok (char *s, const char *delim);Function Description: Strtok () is used to split a string into fragments. The parameter S points to the string to be split, the parameter Delim is the split string,

1. In the function body, a variable declared as static maintains its value in the process of the function being called.2, within the module (but outside the function), such as in a certain C source file, a variable declared as static can be called

First, dynamic_cast relies on rtti information, and secondly, at the time of conversion, dynamic_cast checks whether the converted source object can actually be converted to the target type, which is not syntactically, but a real-world check.First

Limitations of copy arguments (value passing)Scenarios that are not suitable for copying arguments include: When you need to modify the value of an argument in a function. When a large object needs to be passed as an argument. For

See below, when I define a two-dimensional vector in the declaration file of a class, I am prompted to enter the type descriptor;But with the same format definition, the two-dimensional vector is modified in the class to be defined in the source

Before c++11, there was always a problem with how to get high-precision time, and different platforms needed to be obtained in different ways. Now C++11 provides the Chrono. This is one that can solve all the need for time.Three concepts are

As the name implies: Queues that are stored in a sequential structure are called sequential queuesThe cyclic sequential queue avoids the occurrence of false overflow in the queue. As shown, there are several special cases of circular queues.What you

1. When designing a class, you should declare the member variable as private and try to avoid user direct access to member variables, so that users can access members only through function interfaces, which facilitates encapsulation, especially when

Object-oriented and process-oriented differences　　Process-oriented is to analyze the steps required to solve the problem, and then use the function to implement these steps step by one, using a one-time call to be able.Object-oriented is the
