String concatenation is a fundamental feature of the Tcl language, and there is also an <code>append</code> 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> |

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!
Python
File: String_append.py<lang python>#!/usr/bin/env python
- -*- coding: utf-8 -*- #
str = "12345678"; str += "9!"; print(str)</lang>Output:
123456789!
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>
