Bonjour.

Dans ton code, tu compares un String et un entier, il faut donc utiliser '9' et non 9.
De plus, tu compares une chaîne composée de plusieurs caractères avec un seul caractère, donc ça ne pourra jamais retourner quelque chose de correct.
Sinon, pour faire de simples tests, inutiles de travailler sur un array si grand, deux simples valeurs suffisent.

array = ['toto', 'toto45',]

La méthode la plus basique serait de faire.

# Pour chaque élément de l'array
array.each{|el|
    digit = false
    # Pour chaque caractère de l'élément
    el.each_char{|char|
        if char >= '0' and char <= '9'
            # il y a un chiffre
            digit = true
            # On cesse le parcours puisqu'on sait que l'élément contient un chiffre
            break
        end
    }
    puts "#{el}, #{digit}"
}

On peut faire autrement en utilisant un array des chiffres, et utiliser la méthode include? d'Array.

# La syntaxe ('0'..'9') est un Range
nums = ('0'..'9').to_a
array.each{|el|
    digit = false
    el.each_char{|char|
        if nums.include? char
            digit = true
            break
        end
    }
    puts "#{el}, #{digit}"
}

On peut faire bien plus simple avec une expression régulière basique.

array.each{|el|
    digit = el.match('[0-9]') != nil
    puts "#{el}, #{digit}"
}

Une autre méthode qui je pense doit être bien plus lente est de soustraire l'array des chiffres à celui de la chaîne transformée en Array, et de comparer si le résultat est toujours identique à celui de l'array de la chaîne.

nums = ('0'..'9').to_a
array.each{|el|
    # Conversion du String en Array de ses caractères
    chars = el.chars
    digit = chars - nums != chars
    puts "#{el}, #{digit}"
}

Il te reste désormais à implémenter ton compteur, cela ne devrait pas te poser beaucoup de problèmes.
