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.
They both do the same, create an array of n integers on the heap
and set the length to n. You can also use .capacity instead of
.length to allocate n but not adjust length.
