Implementing the Factory Pattern in Embedded Systems: Elegantly Creating Objects with C Language

Introduction In embedded development, have you ever written code like this: creating different objects based on various hardware configurations, resulting in code filled with complex conditional statements? // Confusing object creation logic void* create_sensor(int sensor_type) { if (sensor_type == TEMP_SENSOR) { if (hardware_version == V1) { return create_temp_sensor_v1(); } else if (hardware_version == V2) { … Read more

C++ Programming Tips: Avoid Providing Default Empty Constructors Unless Necessary

1. Default empty constructors are not necessaryCompared to other constructors, the characteristic of a default empty constructor is that it can construct an object without requiring any parameters.However, we cannot always create objects this way in practice. For example, when creating an “ID card” object, the ID number is always required. Therefore, providing a default … Read more
