Question

编写一个Java程序：利用随机函数产生10道两位数的加法题，判断用户得分

提示：产生随机数用以下办法
x=(int)(10+Math.random()*90)
程序运行界面为:
12+34=? Xx
45+67=? xx
...
你的得分为：70

Answer 1

import javax.swing.*;

public class Test {

public static void main(String[] args) {
int score = 0;
for(int i=0; i<10; i++) {
int x = (int)(10+Math.random()*90);
int y = (int)(10+Math.random()*90);
int a = x + y;

JOptionPane.showMessageDialog(null, x+"+"+y+"="+"?");
String input = JOptionPane.showInputDialog("请输入结果");
int b = Integer.parseInt(input);
if(b == a) {
score += 10;
JOptionPane.showMessageDialog(null, "回答正确");
}
else JOptionPane.showMessageDialog(null, "回答错误");

}
JOptionPane.showMessageDialog(null, "你的得分为：" + score);

}

}

Answer 2

public class panduan{
public static void main(String [] args){
int x=(int)(10+Math.random()*90);
int y=(int)(10+Math.random()*90);

int z;
System.out.print(x+"+"+y+"=");
Scanner scanner=new Scanner(System.in);
z=scanner.nextInt();
if(z==y+z){
System.out.println(x+"+"+y+"="+z+" √ ");
}else{
System.out.println(x+"+"+y+"="+z+" × ");
}
}
}

大体上应该是这样的。好些年没写JAVA了。也没测试环境。您看一下是否有帮助

Answer 3

program ss(input,output);
var
a,b,c,i,s:integer;
begin
randomize;

s:=0;

for i:=1 to 10 do
BEGIN
a:=random(100);
b:=random(100);

writeln(a,'+',b,'=');
read(c);

if c=a+b then s:=s+10;
END;

writeln('your score:',c);

END.
