Hi All,

Request your help, with the below code I am able to print the value of the array without brackects , but can some on help me on hot to store this output to a variable

Program:
import std.stdio;
import std.container;

void main()
{
   auto test = Array!string("Test1", "Test2");
   writefln("%(%s, %)",test[]); // output : "Test1", "Test2"

   // Similar like this
   auto res = `writefln("%(%s, %)",test[])`;
   writeln(res);
}

Output of res should look like : "Test1", "Test2" (Without [] brackets).

https://dlang.org/phobos/std_format is your friend:

// https://run.dlang.io/is/sUkOX0

import std.container;
import std.format;
import std.stdio;

void main()
{
   auto test = Array!string("Test1", "Test2");
   writefln("%(%s, %)",test[]);

   // Similar like this
   auto res = "%(%s, %)".format(test[]);
   writeln(res);

   auto res2 = "%-(%s, %)".format(test[]);
   writeln(res2);
}
