What is the simplest way to output every nth element of an
array?
I can do it using a for loop:
void main()
{
int[5] a = [1,2,3,4,5];
for (int i = 0 ; i <= 4 ; i += 2)
{
writeln(a[i]);
}
}
Basically, I am wondering if I missed something.
In addition to the drug's solution, this reminds me of the chunks
of std.range.
import std.range;
import std.stdio;
void main(){
auto source = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
auto chunks = chunks(source, 2);
writeln(chunks[0]); // [1, 2]
foreach(c; chunks)
writeln(c[1]);
}
output:
2
4
6
8
10
