Idiom #153 Concatenate string with integer

Create the string t as the concatenation of the string s and the integer i.

uses Sysutils;
t := s + i.ToString;
uses SysUtils;
t := s + IntToStr(i);
String t = "%s%s".formatted(s, i);
String t = s + i;

The operator + works fine.
t = '{}{}'.format(s, i)
t = '%s%s' % (s, i)
t = s + str(i)
t = f"{s}{i}"

The f in front of the string makes it a Literal String, in which you can put expressions inside brackets
t : String := s & Integer'Image (i);
New implementation...
