I was writing a program that reads and prints the first nth lines
to the stdout:
import std.stdio;
void main(string[] args)
{
import std.algorithm, std.range;
import std.conv;
stdin.byLine.take(args[1].to!ulong).each!writeln;
}
As far as I understand the stdin.byLine.take(args[1].to!ulong)
part reads all the lines written in stdin.
What if I want to make byLine read only and only first nth line?
stdin.byLine(args[1].to!ulong).each!writeln;
Obviously the code above won't work. Is there any efficient
workaround?
