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
Using the malloc Function for Dynamic Memory Allocation in C In C programming, memory management is an important topic, especially when dealing with memory that needs to be dynamically allocated. Dynamic memory allocation allows programs to request a specific amount of memory as needed, without having to declare the size of variables in advance. This … Read more
In the C language, data types refer to a broad system used to declare different types of variables or functions. The type of a variable determines the amount of space it occupies in storage and how the stored bit patterns are interpreted. Index Type and Description 1 Basic Data Types These are arithmetic types, including … Read more
3. Analyzing from the Perspective of Compiler Semantics In fact, we have already covered a lot about the compiler’s understanding of the syntax and semantics of the C language in the previous section. Below, we will further explain this logic from the compiler’s output. In this article, we will first paste the compilation results of … Read more
