下面程序运行的结果是 struct Student { public int age; public string name; public Student(int age, string name) { this.age = age; this.name = name; } } class Program { static void Main(string[] args) { Student stu1 = new Student(18, "小方"); Student stu2 = new Student(24, "小刚"); stu2 = stu1; stu1.age = 30; stu1.name = "小燕"; Console.WriteLine("{1},{0}",stu2.age,stu2.name); } }
举一反三
- 在C#中，下列代码的运行结果是( )（选一项）[br][/br] struct Student { public int age; public string name; public Student(int age,string name) { this.sge = sge; this.name = name; } } public class Test { static void Main() { Student stu1 = new Student(18,"小芳"); Student stu2 = new Student(24,"小刚"); stu2 = stu1; stu1.age = 30; stu1.name = "小燕"; Console.WriteLine(stu2.age); Console.WriteLine(stu2.name); } } A: 18 小芳 B: 18 小燕 C: 30 小燕 D: 30 小芳
- 以下结构体的定义语句中，正确的是______。? struct student {int num; char name[10];int age;}stu;|struct {int num; char name[10];int age;}student; struct student stu;|struct student {int num; char name[10]; int age;}; student stu;|struct student {int num; char name[10];int age;};stu;
- 下列选项中不能够定义一个结构体类型变量stu的是 。 A: struct student { int num; int age; } stu; B: struct student { int num; int age; }; student stu; C: struct {int num; int age; } stu; D: struct student {int num; int age; }; struct student stu;
- 对以下定义，能输出字符串"Mary"的语句是（ ）。struct student { char name[20]; int age; }; struct student stu[100]={"John",16,"Paul",17,"Mary",18 }; A: printf("%s",stu[2].name); B: printf("%s",stu[1].name); C: printf("%s",stu[2]); D: printf("%s",stu[1]);
- 分析下面的程序，输出的结果是？ public class Test { public static void main(String[] args) { final Person p = new Person("张三", 23); p.setName("李四"); p.setAge(24); System.out.println(p); } } class Person { private String name; private int age; public Person() { super(); } public Person(String name, int age) { super(); this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @Override public String toString() { return "我的姓名是:" + name + ",我的年龄是:" + age ; } }
