(The C language is perceivied to be simple, when it isn't:
what's the C type of 60*60*24? How do size_t and unsigned
long int differ? This is one reason why there are so many CVEs...)

How do you print an int in duodecimal (base 12) in C? :-)

Base 16 and others in Ada:

with Ada.Text_IO;

procedure Int_Based is
   use Ada;

   package Duodec_IO is
      new Text_IO.Integer_IO (Natural);

   X : Natural := 123;
begin
   Duodec_IO.Put (X, Base => 3);
   Duodec_IO.Put (X, Base => 8);
   Duodec_IO.Put (X, Base => 10);
   Duodec_IO.Put (X, Base => 12);
   Duodec_IO.Put (X, Base => 16);
   Text_IO.New_Line;
end Int_Based;
