Why do arrays/lists in programming languages begin at 0?
Most languages store arrays in consecutive memory locations. so if A is an array of ten 16 bit values, the first value might be stored in location & 12900, the second would be two bytes later at & 12902, the third at & 12904, etc. If you number your array elements start from 0, it mak…
The Short Answer
Most languages store arrays in consecutive memory locations. so if A is an array of ten 16 bit values, the first value might be stored in location & 12900, the second would be two bytes later at & 12902, the third at & 12904, etc. If you number your array elements start from 0, it makes the math a lot easier. You ask the computer for element A[i], all it has to do is start with the base address ( & 12900) and add i * size the data type (2 bytes) to get the location of A[i].
