Finding a Nanny (day 1) [SLiSW]

=begin
Hello everyone, finally my summer vacations started, so, it's time for a new challenge. This time I will read a book called "Seven Languages in Seven Weeks". Ruby is the first language, and, this is some exercises from day 1. Everyday has exercises, so, I will try to share the most I can. I hope everyone like. Have a nice day ;)

# Exercise (1)
puts 'Ola mundo!'


# Exercise (2)
strToSearch = 'Ola, Ruby'
strToSearch.index('Ruby')


# Exercise (3)
i = 0
while(i < 10)
    puts 'O meu nome'
    i = i + 1
end


# Exercise (4)
i = 1
while(i <= 10)
    puts "Este é o número #{i}"
    i = i + 1
end


# Exercise (5)
#------myruby.rb------

#!/usr/bin/env ruby
puts 'Ola mundo'

then just "ruby myruby.rb" in command line
or (if using linux)
(a) just be sure your file executable by running "chmod +x myruby.rb"
(b) and run "./myruby"

# BONUS Exercise

#------guessnumber.rb------
#!/usr/bin/env ruby

randNumber = rand(10)
found = 0
puts 'Which number between 0 and 10 the program chosen?'
begin
    input = gets
    number = input.chomp.to_i
    if number == randNumber then
        puts 'Congrats! You found the number!'
        found = 1
    else
        puts 'Wrong answer, try again.'
    end
end until found == 1
