Printing Array elements in the same line

Question

Although I searched a bit on google but did not find a quick and easy answer.

So suppose we have an array with, say 3 elements

X[1]={a,b};X[2]={w,f,s};X[3]={t,y,u};

Now I want to print them in the same line using Do loop. I use the code

Do[Print[X[i]],{i,3}]

But it will print in different lines. I also want to add text in between two elements. I tried to wrap everything using Row[] but it didn't work.

Answer 1

The output I want is: "The set is : {a,b} && {w,fs} && {t,yu}". All in a single line

 X[1]={a,b};X[2]={w,f,s};X[3]={t,y,u};

 And @@ (X[#] & /@ Range[3])

 Print["the set is : ", And @@ (X[#] & /@ Range[3])]

if someone wants to use a different in between symbol, like "--" instead of "&&" what changes will be needed?

If "--" is meant to be just normal text of 2 dashes and not some Mathematical operator, then only way I could think of is to make the whole thing string. Something like

str = StringJoin@Riffle[(ToString[X[#]] & /@ Range[3]), "--"];
Print["the set is : ", str]

Answer 2

I would use:

X[1] = {a, b}; X[2] = {w, f, s}; X[3] = {t, y, u};

Row[Array[X, 3], "&&"]
Row[Array[X, 3], "--"]

{a, b} && {w, f, s} && {t, y, u}
{a, b} -- {w, f, s} -- {t, y, u}
