How do I iterate safely under modification with std::vector for embedded targets?

When working with std::vector in C++, particularly on embedded targets where memory and performance are critical, it's important to handle safe iteration even when the vector is being modified. Modifying a vector while iterating through it can lead to undefined behavior, especially if elements are added or removed, as it can invalidate iterators or references. Here are some strategies to safely iterate through a vector while allowing for modifications:

1. **Use Index-Based Iteration**: Iterate using indices. You can adjust the loop counter accordingly when you add or remove elements. 2. **Use Temporary Collection**: Create a copy of the vector or a temporary container to iterate through while modifying the original vector. 3. **Using erase-remove Idiom**: If you need to remove elements during iteration, consider using the erase-remove idiom to handle it safely.
