我是Ruby的新手并且在用户输入方面练习。我编写了以下代码,允许用户连续输入学生姓名,直到他们两次返回。在每次输入之后,程序返回学校中有多少学生,当他们完成输入后,它会打印出学生列表和他们所在的队列。
目前,该队列是硬编码的,我想修改它,以便我可以同时询问名称和队列,程序继续询问此信息,直到用户返回两次。任何帮助真的很感激 - 谢谢:)
puts "Please enter the names of the students"
puts "To finish, just hit return twice"
students = []
name = gets.chomp
while !name.empty? do
students << {name: name, cohort: cohort}
puts "Now we have #{students.count} students"
name = gets.chomp
end
students
end
def print_header
puts "The students of this Academy".center(50)
puts "-----------".center(50)
end
def print(students)
students.each do |student, index|
puts "#{student[:name]} #{student[:cohort]} cohort"
end
end
end
def print_footer(names)
puts "Overall, we have #{names.count} great students".center(50)
end
students = input_students
print_header
print(students)
print_footer(students)
