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
A: 18 小芳
B: 18 小燕
C: 30 小燕
D: 30 小芳
举一反三
- 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); } }
- 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;
- 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]);
- 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;
- 对结构体类型变量定义不正确的是（ ）。 A: B: define STUDENT struct studentSTUDENT{char name;int num;}std; C: struct student{char name;int num;}stu; D: E: define struct student{char name;int num;}STD;STD stu; F: struct{char name;int num;}student;struct student stu;
