Python中类的定义正确的是 A: class Phone: name = "" call(self, name) print(name, "打电话") B: class Phone: name = "" call(self, name) print(name, "打电话") C: class Phone: name = "" def call(self, name): print(name, "打电话") D: class Phone name = "" def call(self, name): print(name, "打电话")

以下代码中，实例方法定义正确的是（） A: class Student: def setName(self,name): self.name=name B: class Student: def setName(name): self.name=name C: class Student: def setName(self): self.name=name D: class Student: def setName(name,self): self.name=name

以下有关类的声明，正确的是 A: class Student(object) def __init__(self, name, score): self.name = name self.score = score B: class Student(object) def __init__(self, name, score) self.name = name self.score = score C: class Student(object)： def __init__(self, name, score): self.name = name self.score = score D: class Student(object)： def __int__(self, name, score): self.name = name self.score = score

有如下定义‏struct person{char name［9］;int age;};‏struct person class［10］={"John",17,"paul",19,"Mary",18,"Adam",16,};‏则能输出字母M的语句是（ ）。‏​‏ A: cout<<class［3］.name; B: cout<<class［3］.name［1］; C: cout<<class［2］.name［1］; D: cout<<class［2］.name［0];

根据下述定义，能输出字母M的语句是：strcut person{char name&#91;9&#93;;int age;};struct person class&#91;10&#93;={"John",17,"Paul",19,"Mary",18,"Adam",16}; A: class[3].name B: class[2].name[0] C: class[3].name[1] D: class[2].name[1]

若有以下定义，则能打印出字母M的语句是（ ）。struct person{ char name[12]; int num;};struct person class[8]={&quot;Linan&quot;,20,&quot;zhanghai&quot;,18,&quot;Maming&quot;,23,&quot;wanghua&quot;,25,&quot;chenqi&quot;,17};? printf(&quot;%c&quot;,class[2].name[1]);|printf(&quot;%c&quot;,class[3].name[1]);|printf(&quot;%c&quot;,class[2].name[0]);|printf(&quot;%c&quot;,class[3].name);

class Person{ static{ System.out.println(name); } private static String name = "hello"; } class Demo{ public static void main(String[] args){ Person p = null; } }

Given： 1.package test； 2. 3.class Target { 4.public String name = "hello"；5.} What can directly access and change the value of the variable name？（） A: any class B: only the Target class C: any class in the test package D: any class that extends Target

Given： 1.package test； 2. 3.class Target { 4.public String name = "hello"；5.} What can directly access and change the value of the variable name？（） A: Aany class B: Bonly the Target class C: Cany class in the test package D: Dany class that extends Target

有dict={"name" : "mary" , "class" : 2 , "id" : "20180129"}，请问dict&#91;"class"&#93;的值是__________。
