C++ usage in embedded systems

Question

What features of C++ should be avoided in embedded systems?

Please classify the answer by reason such as:

• memory usage
• code size
• speed<

Answer 1

Exceptions are likely going to be the most common answer of what to avoid. Most implementations have a fairly large static memory cost, or a runtime memory cost. They also tend to make realtime guarantees harder.

Look here for a pretty good example of a coding standard written for embedded c++.
