2. 编写程序,使它产生10个随机数加法问题,加数是1到15之间的整数,让用户输入答案后验证用户的答案是否正确,每答对一题得10分,统计并最后输出用户得分(原题)
package pro2;
import java.util.Random;
import java.util.*;
public class Dome_4 {
public static void main(String[] args) {
// TODO Auto-generated method stub
int grade = 0;
Scanner input = new Scanner(System.in);
System.out.println("请输入答案");
int s = input.nextInt();
Random r = new Random();
int a = r.nextInt(15);
Random r1 = new Random();
int arr[] = new int[10];
for (int i = 0; i < arr.length; i++) {
arr[i] = r1.nextInt(15);
if (s = arr[i] + a) {
System.out.println("恭喜你做对了" + grade + 10);
}
}
}
}
