C Language Special: 9. Conditional Statements and Branch Control (if, else, switch)

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

Overview of Constants in C Language

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

Application Example of the Observer Pattern in C Language Projects

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

How to Achieve μA-Level Ultra-Low Power Consumption in Embedded Development?

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
