Can we compare strings in ruby.

Question

Like if I got user input hello then I want to put if condition that answers hi and else bye.I did it but it showed an error.

Answer 1

lndeed it is possible to compare two strings.
Your if/else block should have a string as a condition too.
For example:

inp = gets
if inp == "Hello"
puts "Hi"
else
puts "Ok."

Maybe your mistake was in putting the "=" operator instead of "==" in creating the condition.

Answer 2

inp = gets .chomp
if inp == "Hello"
puts "Hi"
else
puts "Bye"
end

chomp removes the line break from the string

Answer 3

Anis it showed Ok only when I entered Hello also.??
