c++ - 对象和数组

Question

如何创建对象数组并添加对象，如下所示：

Student* student11 = new Student("Vince", "Vaughn", "7-th Avenue", "New York", "783-945-90-28", 49);
    Student* student12 = new Student("Vince", "Mcmahon", "Beverly Hills", "Los Angeles", "874-940-42-12", 47);
    Student* student13 = new Student("Stone Cold", "Steve Austin", "Dallas", "Texas", "385-421-47-95", 34);

Answer 1

看来你的意思如下

Student *student = new Student[3] 
{
    { "Vince", "Vaughn", "7-th Avenue", "New York", "783-945-90-28", 49 },
    { "Vince", "Mcmahon", "Beverly Hills", "Los Angeles", "874-940-42-12", 47 },
    { "Stone Cold", "Steve Austin", "Dallas", "Texas", "385-421-47-95", 34 }
};

Student如果类没有默认构造函数并且您需要重新分配数组，则可能会出现问题。

因此请注意，您可以使用标准模板类，而不是“手动”分配数组std::vector<Student>。
