Stand-alone 2D array on the heap and a pointer in `basket` ...doing that now!
Thanks for dragging me away from my obsession with squeezing a 2D declaration into the struct. (more) |

The data in the basket(s) is ALL from user-provided .txt files. The files are parsed, impossible data filtered out, and residual fed to the basket(s). From that moment (±0.02sec into the run) the basket(s) do not change: no edits; no realloc; NO flexibility.
"...accept that the data is stored else... (more) |

Thanks @celtschk for your suggestion: essentially a lookup-table into a (renamed) `char *items`. It would work, BUT Ignoring the inevitable memory inflation (237% in a simple test-case), the array-of-pointers look-up is not fast! Speed is a concern since the code must look (and re-look) millions of t... (more) |

Data are values that fit comfortably in a char, NOT strings. They may match a "dictionary word" in some language, but are NEVER used in any string-like context (string.h, printf...%s, etc).
Execution speed is important: the code will access `baskets[]` millions of times in a run, how many millions... (more) |

| Question | — |
2D-array pointer as a struct member I have an array of struct: ``` static struct basket baskets[MAXITEMLEN + 1]; struct basket { char items; // malloc(itemlen itemcount) int itemcount; }; ``` `char items` does all I need to do with some pointer-gymnastics, but at times it gets a little ugly. I would prefer a 2D... (more) |
