This textbook features a unique parallel presentation of materials in both C and Pascal programming languages, enabling learners to grasp concepts more quickly and efficiently. An overview of development environments for technical programming demonstrates their equal suitability for creating software for microprocessor systems. The book is designed for university students specializing in Radioelectronic Devices Design and Technology (program code 210201), as well as undergraduates in Electronic Devices Design and Technology (210200), Infocommunication Technologies and Communication Systems (210700), and Electronic Devices Engineering and Technology (211000). It supports the study of courses related to production efficiency, and is also a valuable resource for coursework, final projects, master's theses, and technical-economic evaluations of market potential for various developments.
