Ruby Case Statement

In Ruby, we use ‘case’ instead of ‘switch’ and ‘when’ instead of ‘case’. The case statement matches one statement with multiple conditions just like a switch statement in other languages.

Syntax:

case expression  

[when expression [, expression ...] [then]  

   code ]...  

[else  

   code ]  

end

Example:

#!/usr/bin/ruby   

print "Enter your day: "   

day = gets.chomp   

case day   

when "Tuesday"   

  puts 'Wear Red or Orange'   

when "Wednesday"   

  puts 'Wear Green'   

when "Thursday"   

  puts 'Wear Yellow'   

 when "Friday"   

  puts 'Wear White'   

 when "Saturday"   

  puts 'Wear Black'   

else   

  puts "Wear Any color"   

end

Output:

Look at the above output, conditions are case sensitive. Hence, the output for ‘Saturday’ and ‘saturday’ are different.
