In the C language, we have learned about basic data types such as char, short, int, long, etc., and we have also learned how to construct collections of data using arrays. However, in different situations, we often need to combine different data types to form a new data structure.For example, when writing a student information … Read more
1. Understanding MATLAB 1. Overview of MATLAB (1) In universities across Europe and America, MATLAB has become a fundamental teaching tool for courses in linear algebra, automatic control theory, digital signal processing, time series analysis, dynamic system simulation, image processing, and more. It is a basic skill that undergraduate, master’s, and doctoral students must master. … Read more
▼Click the card below to follow our public account ▼ Today, embedded systems are increasingly applied in various fields such as smart homes, smart healthcare, industrial automation, and intelligent transportation. In the process of embedded system development, data structures are an essential knowledge point. This article will introduce several common data structures in embedded programming, … Read more
Like other programming languages, in C++, an array is a collection of similar types of elements with contiguous memory locations. In C++, std::array is a container that encapsulates fixed-size arrays. In C++, array indexing starts at 0. We can only store a fixed number of elements in a C++ array. In C/C++ programming languages or … Read more

Click the blue words Follow us Function Pointers Functions also have their own addresses; the function name/&function name is the address of the function. 1.1 Basic Form In the study of array pointers, we learned that int arr[5];int (*pa)[5] = &arr;//pa is an array pointer The type of pointer variable pa is int(*)[5]. So what … Read more
An array is a collection of data items of the same type stored at contiguous memory locations. Arrays are derived data types in C that can store primitive data types (like int, char, double, float) as well as derived data types (like pointers, structures, etc.). Arrays are the simplest data structure, allowing random access to … Read more
The for loop in C language is used to execute a statement or a part of a program multiple times. It is often used to traverse data structures such as arrays and linked lists. The syntax of the for loop in C is as follows: for (Expression 1; Expression 2; Expression 3) { // Code … Read more
◆Key Point 1: Method to Swap Two Variable Values 1) Using a third variable (the easiest method) 2) Using addition and subtraction to swap values (commonly used in interviews **) The code is as follows: b = a – b; a = a – b; b = a + b; 3) Using bitwise XOR to … Read more
Pointer Operations Pointer operations give it powerful functionality. In addition to the dereference operation (*) and the address-of operation (&), pointers also support some arithmetic operations. For example, pointers can perform addition and subtraction, but it is important to note that pointer addition and subtraction are not simple numerical addition or subtraction; they are based … Read more
