Accumulation AlgorithmThe accumulation algorithm in C language is one of its fundamental algorithms, primarily used to sum values through looping methods, such as using a for loop to calculate the sum of all elements in a known array (it seems that the standard library in C does not have built-in methods for summing arrays).In some … Read more
In C language, conditional judgment statements such as <span>if</span>, <span>else if</span>, <span>else</span>, and <span>switch-case</span> allow different code paths to be executed based on various conditions. This is the foundation for writing logical control programs. Before diving into the main content, let’s first review the definition and structure of functions in C language. 1. Function Definition … Read more
Cumulative Product AlgorithmThe cumulative product algorithm in C language, as the name suggests, is the product obtained by multiplying a set of data together, such as a*b*c*d*e.The cumulative product algorithm is one of the basic algorithms in C language, commonly used to calculate the product of all elements in an array (for example, in statistics … Read more
1. Arithmetic Operators Arithmetic operators are used to perform basic mathematical operations, including addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). Below is a sample program demonstrating the usage of these operators: #include<stdio.h> int main() { int a = 10; int b = 3; printf("a + b = %d\n", a + b); … Read more
1. Overview of Constants A constant is a value that cannot be changed during the execution of a program. Unlike variables, which can change their values at runtime, once a constant is defined, its value cannot be altered. Constants play an important role in programs as they enhance code readability and maintainability, and they also … Read more
Hello everyone, welcome to <span>LiXin Embedded</span>. In embedded development, structures are an indispensable tool. Compared to classes in object-oriented programming, C language structures are more like pure data collections without methods, making them simple and efficient. For embedded engineers, it is essential to not only use structures conveniently but also to understand their layout in … Read more
C Language: The Programming Cornerstone and Technical Legend of Half a Century I am Feri, a veteran with 12 years of experience in the coding world. From Java to HarmonyOS, from embedded systems to AI, I firmly believe that the foundation of all complex systems lies in the most basic languages. Today, let us unveil … Read more
Application Example of the Observer Pattern in C Language Projects The Observer Pattern is a behavioral design pattern that defines a one-to-many dependency between objects, so that when one object (the subject) changes state, all its dependents (the observers) are notified and updated automatically. This pattern is widely used in event handling systems, GUI frameworks, … Read more
1 Case Situation A semiconductor manufacturing plant generates a large amount of wastewater containing heavy metals during production, including copper, nickel, zinc, and lead, which pose serious potential hazards to the environment. The plant’s original wastewater treatment system, while capable of removing some pollutants, is ineffective in removing heavy metals, resulting in wastewater that cannot … Read more
Click the above blue text to follow us μA-level power consumption refers to a system that consumes only microampere-level current during normal operation or idle state. Typically, both static power consumption (sleep or idle mode) and dynamic power consumption (active mode) are strictly controlled. For example, a system may consume only 0.5μA in deep sleep … Read more
