This document provides an agenda for a training course on programming embedded systems in C++. The agenda covers topics such as using C++ for embedded programming, migrating from C to C++, using C++ with a real-time operating system, and case studies. The document also discusses why C++ has not been more widely adopted for embedded programming, noting concerns about code bloat, performance and dynamic memory, as well as early failures of tools and programming practices. It provides a brief history of the development of C++ from languages like BCPL and B and outlines some limitations of C for embedded programming, such as its low-level capabilities that can make code dangerous and hard to maintain for large projects.

4. Why is C++ Not More Widely Used?
• Conservatism
– “If it ain’t broke, don’t fix it”
• Early attempts failed
– bad tools
– inappropriate programming practice
• Fears
– code bloat
– performance
– dynamic memory

8. Limitations of C
• C is extremely powerful and flexible and can therefore
be dangerous
– It has low level capabilities (which are useful for
embedded)
– There are many pitfalls for the unwary
• Programmers need to be very methodical and
disciplined
• Programmers need to understand how the program
behaves at low and high levels
– Large projects are thus hard to maintain
• Programmers need an expert knowledge of the
application
