Section 5.7 Summary and Reading Questions
A statically allocated C++ array is an ordered collection of one or more C++ data values of identical type stored in contiguous memory.
A vector is a dynamically allocated array with many useful methods. It is more similar to the Python list than the array.
C++ strings are a sequential collection of zero or more characters. They are very similar to Python strings.
A hash table is used to store keys-value pairs. It applies a related hash function to the key in order to compute the location of the associated value. Look-up is typically very fast.
A set is an unordered collection of unique values.

1.
Which C++ structure is the best choice for a group of ordered data of a fixed length?
Correct!
No. hash tables are not ordered.
A string would only work for character data. Try again.
There is a better choice given that the group is fixed length.
more than one of the above
Only of the above is best.
