STL common algorithms: Write at the beginning: sort out some algorithms commonly used in stl, involving comparison, exchange, search, traversal, replication, modification, etc. It's worth collecting!! summary: The algorithm is mainly composed of header files < algorithm > < functional > < numeric >.< algorithm > ...

1, Generic programming style:    in the process of learning, I think "pan" here refers to more "extensive" and "general", which has stronger universality. The processing methods of different data types can be solved with the same function instead of writing functions with the same function for different ...

First, let's look at an example: If we don't consider overtime, we can use the most simple method (violence) to solve it //Violence algorithm (n*m) int ViolentMatch(char *s,char *p) { int sLen = strlen(s); int pLen = strlen(p); int i = 0; int j = 0; while(i<sLen&&j<pLen) { if(s[i]==p[j]) { i++; j++; } ...

1. The default six member functions of the class If a class has no members, it is called an empty class. Is there nothing in the empty class? Not really. If we don't write any class, the following six default member functions will be automatically generated. This is the complex initialization mechanism of C + +. class Date{} They are ...

BC11 student basic information input and output describe Input a student's student number and 3 subjects (C language, mathematics, English) scores in turn, and output the student's student number and 3 subjects' scores on the screen (Note: the scores shall be rounded and 2 decimal places shall be reserved). Data range: student number mee ...

Overload of assignment operator Operator overloading In order to enhance the readability of the code, C + + introduces operator overloading. Operator overloading is a function with special function name, and also has its return value type, function name and parameter list. Its return value type and parameter list are similar to ordinary f ...

1, Preliminary understanding of process oriented and object oriented C language is process oriented, focusing on the process, analyzing the steps of solving the problem, and gradually solving the problem through function call. C + + is based on object-oriented and focuses on objects. It divides a thing into different objects and complete ...

catalogue Namespace Definition of namespace C + + input & output Default parameters Function overloading (important syntax knowledge in C + +) Namespace stay C/C++ There are a large number of variables, functions and classes to be learned later. The names of these variables, functions and classes will all exist in the gl ...
