WebZero-length arrays are allowed in GNU C. They are very useful as the last element of a structure that is really a header for a variable-length object: struct line { int length; char contents [0]; }; struct line *thisline = (struct line *) malloc (sizeof (struct line) + this_length); thisline->length = this_length; WebOct 1, 2024 · Arrays are zero indexed: an array with n elements is indexed from 0 to n-1.
