Equivalent to write(args, '\n'). Calling writeln without arguments is valid and just prints a newline to the standard output.

Prototype

void writeln(T...)(
  T args
);

Parameters

NameDescription
args the items to write to stdout

Throws

In case of an I/O error, throws an StdioException.

Example

Reads stdin and writes it to stdout with a argument counter.

import std.stdio;

void main()
{
    string line;

    for (size_t count = 0; (line = readln) !is null; count++)
    {
         writeln("Input ", count, ": ", line);
    }
}
