C/C++

Definition

C/C++ are closely related programming languages that are widely used in software development, particularly in embedded systems and IoT applications. C is a procedural programming language that offers low-level access to memory and system resources, while C++ extends C with object-oriented features, allowing for more complex program design and better code organization. Together, they provide powerful tools for developers working with hardware and real-time systems.
