Click the aboveblue text to follow us In C language development for microcontrollers, the use of global variables is indeed very common. This programming style is mainly due to several important reasons: 1 Performance and Resource Constraints In embedded systems, resources (such as memory and CPU time) are often very limited. Using global variables can … Read more
Pointers and Arrays: An In-Depth Analysis of Their Close Relationship in C Language In C language, pointers and arrays are two very important concepts, and they are closely related. Understanding the relationship between the two is crucial for mastering C programming. 1. What is a Pointer? A pointer is a variable used to store a … Read more
Today, let’s talk about pointers in C language—this “address navigator” in the programming world. Pointers are like a “GPS” in programming, helping us accurately locate and manipulate data in memory. Mastering the essence of pointers will elevate your programming skills to a new level. Definition of Pointers and Memory Addresses In C language, pointers are … Read more
First, let’s address two questions ◆ What are the differences between pointers and references? ◆ When should we use pointers? When should we use references? Differences between Pointers and References See the code below: A pointer is used to represent a memory address, and this pointer is the address of the variable it points to. … Read more
The Role of C Language in Deep Learning: Methods and Examples In the field of deep learning, Python is often the preferred programming language due to its vast ecosystem and rich library support. However, in certain specific scenarios, the C language is particularly important due to its high performance and low-level control capabilities. In this … Read more
Basics of Pointers: Concepts and Declarations of Pointers in C Language In C language, pointers are a very important concept. They allow programmers to directly manipulate memory, enabling efficient data processing and flexible data structures. This article will detail the basic concepts of pointers, how to declare pointers, and provide some simple code examples. What … Read more
Simulation and Application of Namespaces in C Language In programming, the concept of namespace is important for organizing code and avoiding naming conflicts. Many modern programming languages, such as C++ and Java, have built-in support for namespaces. However, C language does not provide direct namespace functionality. This article will introduce how to simulate namespaces in … Read more
5.Why Create the Array Data Structure From the previous analysis, we can understand that the essence of an array name is a pointer. Since we already have the pointer data type, why create the array data type? Isn’t that redundant? Can we program normally without creating arrays? The answer is: Yes, it is indeed possible … Read more
⚡ The Dominance of Global Variables in Microcontroller Development Global variables, often “disliked” in desktop application development, are widely used in the field of microcontrollers. This seemingly contradictory phenomenon hides the unique operating environment and development constraints of embedded systems. // Typical microcontroller program structure volatile uint8_t flag = 0; // Interrupt flag uint32_t system_ticks … Read more
Using C language to create a meteor shower animation, the effect is as follows: Core Steps: 1. First, set up the drawing window with a size of 640×480, and set the center origin coordinates to (320, 240): 2. Randomly generate stars and meteors within the window. The colors of the stars are random to enhance … Read more
