Step by Step solution about How to resolve the algorithm Terminal control/Display an extended character step by step in the Ruby programming language

The code snippet you provided is a Ruby program that prints the British pound sign (£) to the console.

The first line of the code, #encoding: UTF-8, is a comment that specifies the encoding of the source file. This comment is superfluous in Ruby versions greater than 1.9.3, as Ruby automatically detects the encoding of source files.

The second line of the code, puts "£", prints the British pound sign (£) to the console. The puts method is used to print data to the console, and the string "£" contains the British pound sign.

When this code is executed, it will print the British pound sign (£) to the console.

#encoding: UTF-8  #superfluous in Ruby > 1.9.3
puts "£"
