Chapter 2: Challenges in Embedded Systems with Limited Resources

Standalone examples exploring the cost and control of dynamic memory allocation.

Each example is a single self-contained file — paste it into Compiler Explorer to build it, run it, and inspect the generated assembly.

The folder contains following examples:

• vector_dyn_mem.cpp — how std::vector growth triggers repeated allocations
• vector_dyn_mem_reserve.cpp — taming reallocation with reserve()
• vector_pmr.cpp — std::pmr vectors backed by a fixed buffer instead of the heap
• new_deleted.cpp — banning heap allocation by deleting operator new
• terminate_handler.cpp — a custom terminate handler
• instrument_functions.cpp — tracing calls with function instrumentation (add -finstrument-functions to the compiler options in Compiler Explorer)
