What are the strengths and limitations of arrays? What considerations go into choosing an array over another data structure, or vice-versa?

Here a simple answer is;

  • Arrays

    • allow fast random access in $\mathcal{O}(1)$ to their elements since and they are sequential in memory.
    • $\mathcal{O}(1)$ time write or update an element
    • if not created in heap memory size is very limited.
    • The size is fixed.
  • Vectors

    • Access and write is similar to array
    • The size not fixed. When capacity is full, extended.
