You are encouraged to solve this task according to the task description, using any language you may know.
Basic Data Operation
This is a basic data operation. It represents a fundamental action on a basic data type.
You may see other such operations in the Basic Data Operations category, or:

Create a string variable equal to any text value. Append the string variable with another string literal.
To illustrate the operation, show the content of the variable.
ALGOL 68
File: String_append.a68<lang algol68>#!/usr/bin/a68g --script #
- -*- coding: utf-8 -*- #
STRING str := "12345678"; str +:= "9!"; print(str)</lang>Output:
123456789!
BBC BASIC
<lang BBC BASIC> S$="Hello"
S$+=" World!" PRINT S$ END</lang>
- Output:
Hello World!
D
<lang d>import std.stdio;
void main() {
string s = "Hello"; s ~= " world!"; writeln(s);
}</lang>
- Output:
Hello world!
Perl 6
<lang perl6>my $str = "foo"; $str ~= "bar"; say $str;</lang>
- Output:
foobar
Python
File: String_append.py<lang python>#!/usr/bin/env python
- -*- coding: utf-8 -*- #
str = "12345678"; str += "9!"; print(str)</lang>Output:
123456789!
REXX
<lang rexx>s='he' s=s'llo world!' Say s</lang> Output:
hello world!
Tcl
String concatenation is a fundamental feature of the Tcl language, and there is also an append
that makes concatenation even simpler:
<lang tcl>set s "he"
set s "${s}llo wo"; # The braces distinguish varname from text to concatenate
append s "rld"
puts $s</lang>
- Output:
hello world
Wart
<lang wart>s <- "12345678" s <- (s + "9!")</lang>
