Ruby : the while loop does not work

I have a problem with my while loop. The loop displays directly from last puts without asking for the number that is to guess (adeviner).

adeviner = 4
a = 0

while adeviner != 4
  puts "Entrez votre chiffre"
  a = gets.chomp.to_i
end

puts "vous avez devine le chiffre"

Here is what the console returns:

ruby test.rb
vous avez devine le chiffre

I would like the console to ask me to type a number and tell me if that number is good or not.

I think you are accidentally using the wrong variable in your loop 

adeviner = 4
a = 0

while a!= adeviner
    puts "Entrez votre chiffre"
    a = gets.chomp.to_i
end

puts "vous avez devine le chiffre"

The code above uses the a variable in the loop. a is initally set to a default of 0 (which is not the number we are trying to guess) and the loop continues until the user correctly inputs "adeviner" value.

Your while block is executed while the condition is true but your condition is never true (4 != 4 is false)
