A string in Nim is very similar to a sequence of characters. However, strings in Nim are both zero-terminated and have a length field. One can retrieve the length with the builtin ``len`` procedure; the length never counts the terminating zero. + +The terminating zero cannot be accessed unless the string is converted +to the ``cstring`` type first. The terminating zero assures that this +conversion can be done in O(1) and without any allocations. + The assignment operator for strings always copies the string. The ``&`` operator concatenates strings. |
