In Very High level languages, such as scilab, you can write
array_var = (1,2,3 ... etc)
and then you can also write
array_var = array_var(1:2,4:$)
In this case, the third element is dropped, and the same
variable,
array_var is set to be an array of a different length,
resizing of array
and so on is automated.
Is the same possible to be done in D?
say,
int [] a ; //initialize;
a ~= 1;
a ~= 2; //etc, polulate
. . . say, we fill up 10 such elements
Now, can you do like,
a = somefunction_that_drops_the_4th_element(a); // a is reset,
// and the
length
// is
reorganized
automatically
There is also chain() which works with ranges other than slices
as well:
import std.array;
import std.range;
import std.algorithm;
void main()
{
auto a = 10.iota.array;
auto skipped = chain(a[0..3], a[4..$]);
assert (skipped.equal([ 0, 1, 2, 4, 5, 6, 7, 8, 9 ]));
}
