1. Introduction to Microcontrollers: The Fog and Breakthrough of C Language Entering the world of microcontrollers, many students first face the steep learning curve of the C language. Opening Keil, the screen filled with if, else, for, while statements feels like a secret code, and long variable names like GPIO_InitTypeDef and Delay_ms can be daunting. … Read more
1. Introduction to the advantages of C language for microcontrollers in conjunction with the 8051: · No need to understand the specific hardware of the microcontroller to write professional-level programs that conform to the actual hardware; · No need to understand the instruction set of the microcontroller to write perfect microcontroller programs; · Different function … Read more
The Design Philosophy of C Language The design philosophy of C language can be summarized as “Trust the Programmer“. Unlike many modern programming languages, C language imposes very few restrictions on the behavior of programmers, assuming that programmers know what they are doing. Thus, C language is actually a language that demands a lot from … Read more
Scan and follow to learn embedded systems together, grow together. C is a very popular programming language due to its simplicity and wide application across various fields. However, due to the characteristics of C, it is also prone to certain errors and traps that can lead to program crashes, data loss, or security vulnerabilities. This … Read more
User Comments: @Gai-Not Responsible:Then it should be called Go language @Hao He2:Then why not call it G language @Zephyr112252:Go, you are not worthy @Bei_inNoNite:Oh
1. Core Features and Memory Layout Principles of Union A union is a special data structure in C language, characterized by all members sharing the same memory space, with the size determined by the largest member. This design allows unions to achieve type punning through memory reuse, playing an irreplaceable role in scenarios such as … Read more
01 (Multiple Choice) The basic data types in C language include A) Integer B) Floating-point C) Logical D) Character Answer: ABD Analysis: For option C: Logical type is not a basic data type in C language. In standard C (C89/C90), there is no native boolean type, which is usually replaced by int (0 represents false, … Read more
01 Among the following function definitions, the one that will cause a compilationerror is A) max(int x, int y, int* z) { *z = x>y?x:y; } B) int max(int x, y) { int z; z = x>y?x:y; return z;} C) max(int x, int y) { int z; z = x>y?x:y; return(z);} D) int max(int x, … Read more
Implementation of Data Structures and Algorithm Applications in C Language In computer science, data structures and algorithms are fundamental and important concepts. They help us efficiently store, organize, and process data. In this article, we will introduce several common data structures and their implementations in C language, and demonstrate how to use these data structures … Read more
1. Common Operators in C Language: Classification and Function Introduction Classification Operator Symbol Function Description Arithmetic Operators <span>+</span>、<span>-</span>、<span>*</span>、<span>/</span>、<span>%</span>、<span>++</span>、<span>–</span> Used for basic mathematical operations such as addition, subtraction, multiplication, division, modulus, as well as increment and decrement operations. The division operator <span>/</span> uses <span>truncation towards zero</span> (after C99), for example: -7/2 = -3. The modulus operator … Read more
