Question

我在第6章中列出了6.21，添加了REGEX以进行正确的电子邮件验证，并仔细检查了user.rb和user_test.rb，无法弄清楚如何得到以下错误。

FAIL["test_should_be_valid", UserTest, 6.092359365000448]
 test_should_be_valid#UserTest (6.09s)
        Expected false to be truthy.
        test/models/user_test.rb:10:in `block in <class:UserTest>'

这是我的user.rb

class User < ApplicationRecord
  validates :name, presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, length: { maximum: 255 },
  format: { with: VALID_EMAIL_REGEX }
end

这是我的user_test.rb

require 'test_helper'

class UserTest < ActiveSupport::TestCase

  def setup
    @user = User.new(name: "Example User", email: "user@example,com")
  end

  test "should be valid" do
    assert @user.valid?
  end

  test "name should be present" do
    @user.name = "    "
    assert_not @user.valid?
  end

  test "email should be present" do
    @user.email = "   "
    assert_not @user.valid?
  end

  test "name should not be too long" do
    @user.name = "a" * 51
    assert_not @user.valid?
  end

  test "email should not be too long" do
    @user.email = "a" * 244 + "@example.com"
    assert_not @user.valid?
  end

  test "email validation should accept valid addresses" do
    valid_addresses = %w[user@example.com USER@foo.COM A_US-ER@foo.bar.org first.last@foo.jp alice+bob@baz.cn]
    valid_addresses.each do |valid_address|
      @user.email = valid_address
      assert @user.valid?, "#{valid_address.inspect} should be valid"
    end
  end

  test "email validation should reject invalid addresses" do
    invalid_addresses = %w[user@example,com user_at_foo.org user.name@example. foo@bar_baz.com foo@bar+baz.com]
    invalid_addresses.each do |invalid_address|
      @user.email = invalid_address
      assert_not @user.valid?, "#{invalid_address.inspect} should be invalid"
    end
  end
end

Answer 1

typedef struct Node {
    char data;  // in this case we save char symb
    struct Node *next;
}Node;

typedef struct Stack {
    struct Node* topElem;
}Stack;

void push(Stack* stack, char data) {
    Node* tmp = (Node*)malloc(1 * sizeof(Node));
    if(!tmp) {
        printf("Can't push!\n");
        return;
    }
    tmp->data = data;
    tmp->next = stack->topElem;
    stack->topElem = tmp;  // making new top element
}

char pop(Stack* stack) {
    Node* tmp = stack->topElem;
    char del_data = stack->topElem->data;
    stack->topElem = stack->topElem->next;
    free(tmp);
    return del_data;
}

该电子邮件无效。它里面有一个逗号。
