Arrays are useful when you want your data allocated on the stack rather than
the heap (we will discuss the stack and the heap more in [Chapter
4][stack-and-heap]<!-- ignore -->) or when you want to ensure you always have a
fixed number of elements. An array isn’t as flexible as the vector type,
though. A *vector* is a similar collection type provided by the standard
library that *is* allowed to grow or shrink in size. If you’re unsure whether
to use an array or a vector, chances are you should use a vector. [Chapter
8][vectors]<!-- ignore --> discusses vectors in more detail.
Arrays are useful when you want your data allocated on the stack, the same as
the other types we have seen so far, rather than the heap (we will discuss the

However, arrays are more useful when you know the number of elements will not
need to change. For example, if you were using the names of the month in a
