C_String := Interfaces.C.Strings.New_String
   (Your_Integer_Type'Image (Variable_Of_Your_Integer_Type) );

'Image returns a String of minimal length for the value in base 10. The
first character of the String is a space for a non-negative value and
'-' for a negative value. So

 -1 => "-1"
-10 => "-10"
  0 => " 0"
 10 => " 10"
100 => " 100"

If you need a fixed width or another base, look at
Ada.Text_Io.Integer_Io.Put with an out parameter of type String.
