0Today we wrote a few minor functions to our Vector class (which is fixed at a capacity of 10, unlike a normal vector which will resize its capacity upwards when it fills up), including pop_back, is_empty (a better name than .empty), clear, and most interestingly how to add iterator support to it. Pointers are iterators, so just returning a pointer to the beginning and 1+ the end of arr is all it takes to make .begin() and .end() work, which means our little vector class here works with range-based for loops.
