C++ is one of the most preferred languages for developing IoT applications and devices.

As an extension of the C language, C++ boasts embedded programming and low-level project capabilities, which are essential for developing IoT devices. C++ is a middle-level language whose object-oriented programming capability is best for low-level memory management. In addition, the language is designed for constrained devices and extensive systems. Rust has gained significant popularity in recent years owing to its ability to meet system programming needs. Segmentation faults (segfault) such as those associated with C++ are limited in Rust. They are a result of thread safety and memory safety issues.
