novice questions 2This is a discussion on novice questions 2 within the Eiffel forums in Programming Languages category; Forgot one: Does Eiffel have resizeable arrays? (something like C++ std::vector). If you define std::vector<int> for example, the memory layout of the elements is similar to int[] (i.e. it's unboxed), which is why STL vectors are as fast as C arrays, but you can add elements to them. Does Eiffel (SmartEiffel) offer similar facilities?... | ||||||||

What are they called (so I can look them up in the docs) ? |

An ARRAY in Eiffel is typically one chunk of memory for the items. There are also linked lists. Not in every case one chunk of memory has the best performance... Ulrich |
