How do I handle errors with std::vector in C++11?

What are some common errors I might encounter when using std::vector in C++11?

Common errors include out-of-bounds access, memory allocation failures, and iterator invalidation.

How can I prevent out-of-bounds access with std::vector?

You can use the .at() method instead of the subscript operator, as it performs bounds checking.

What should I do if I encounter a memory allocation failure?

You should handle it using try-catch blocks to catch std::bad_alloc exceptions.

Can you explain iterator invalidation?

Iterator invalidation occurs when the vector is modified, such as during insertions or deletions, which can make existing iterators unusable.
