C: this low-level programming language is often used for embedded software development since it offers efficient memory management and hardware access.
It is also a simpler language than C++ and can be easier to learn.
Many popular microcontroller platforms, such as the AVR and ARM Cortex-M, are programmed using C.
For embedded systems, especially those with real-time requirements, C is by far the most used, followed by C++.
Rust is a very distant third, at the time of this writing.
Python, which typically has garbage collection, is not appropriate for embedded systems with real-time requirements.
C++ is commonly used in embedded systems development, such as in automotive, IoT devices, and medical devices.
Embedded system developers use C++ to write firmware and software for these devices.
