In Mr. Cehreli's book it says
Additionally, the length of dynamic arrays can be changed by
assigning a value to this property:
int[] array; // initially empty
array.length = 5; // now has 5 elements
while in Mr. Alexandrescu's book, it says
To create a dynamic array, use a new expression (§ 2.3.6.1 on
page 51) as follows:
int[] array = new int[20]; // Create an array of 20 integers
Could someone please compare and contrast the two syntaxes. I
presume the "new" command places the 2nd array in heap memory.
I would have read the second as creating a static array of 20
ints in heap memory, then assigning a dynamic array to point to
it. The first one definitely does what you'd expect.
Wasn't Andres book based on D1.0? Or has he done another since
then?
