Hi All,
Request you help on printing an array in below,
Eg:
Array ("T1", "T2", "T3", "T4", "T5")
Output required as below
T1,T2
T2,T3
T3,T4
T4,T5

2.079 [1, 2] will ship with slide:
---
auto arr = ["T1", "T2", "T3", "T4", "T5"];
arr.slide(2).each!writeln;

slide is super-powered with a lot of nice things to generate
sliding windows lazily, but for this simple case, it's enough to
do:
---
auto arr = ["T1", "T2", "T3", "T4", "T5"];
arr.zip(arr.dropOne).each!(a => writefln("%s,%s", a[0], a[1]));

or of course, as Adam pointed out, good 'ld array iteration works
too:
---
auto arr = ["T1", "T2", "T3", "T4", "T5"];
foreach (i; 0 .. arr.length - 1)
writefln("%s,%s", arr[i], arr[i + 1]);
