Hi All,
Request your help on reserve an dynamic array when the capacity is
reached to a point(eg: 80%) so the array to extend the reserve by
next 20%
Example:
Array!string Test;
Test. reserve(100) - Initall
Test =(.........) - The number of entries are dynamic
if (array.capacity > 80%) { array.reserve(100+20%)
There's a "capacity" property which you can use. Compare that to the
length of the array to know when it has reach 80%.
Hi Jacob,
Thank you , yes we can use the length property and calculate the
capacity, but the question is how to implement it dynamically, so let me
explain a bit further.
Array should automatically increase the size as you need more data. And
it amortizes the extensions, so instead of adding a constant number of
elements (as you are proposing), it multiplies the capacity by some
value. So you end up with better performance.
I think you are fine to just use Array and not worry about the
reallocations, they are handled automatically.
