考题 下列程序的输出结果是【 】。 includeclass MyClass{public: int number; void set(in 下列程序的输出结果是【 】。include<iostream. h>class MyClass{public:int number;void set(int i);};int number=3;void MyClass: :set (int i){number=i;}void main( ){MyClass my1;int number=10;my1.set(5),cout<<my1, number<<',';my1.set(number);cout<<my1.number<<',';my1.set(: :number);cout<<my1.number<<'.';}

考题 阅读以下说明和Java代码,将应填入(n)处的语句写在对应栏内。【说明】进行两个整数之间的比较,由考生通过输入窗口分别输入两个整数,程序比较出结果。例如:先后输入的两个数分别为25和36。比较结果显示:25!=3625<3625<=36【Java代码】import javax.swing.JOptionPane;public class Java3{public static void main(String args[]){String (1) // 用户输入第1个字符串secondNumber, // 用户输入第2个字符串result; // 包含输出int number1, // 比较的第1个数number2; // 比较的第2个数// 用户输入的第1个字符串firstNumber =JOptionPane.
