【中文标题】数学:除法问题生成器【英文标题】:Math: Division Problems Generator 【发布时间】:2014-09-25 21:46:38 【问题描述】:我正在制作一个程序,询问您是否想做加法、减法、乘法和除法。然后它会询问多少个问题。除了除法之外,我一切正常。我想确保在做除法问题时不会有余数。我不知道如何使这项工作。
else if (player==4)
System.out.print("How many questions would you like?-->"); player =
in.nextInt(); numQuestions= player;
do
//question
do
do
num1 = (int) (Math.random() * 100);
num2 = (int) (Math.random() *10);
while (num2 > num1);
while (num1 % num2 == 0);
compAnswer = num1 / num2;
System.out.println(num1+" / " + num2 + "=");
System.out.print("What's your answer? -->");
player = in.nextInt();
if (player == compAnswer)
System.out.println(" That's right, the answer is "
+ compAnswer);
System.out.println("");
score++;
else
System.out.println("That's wrong! The answer was "
+ compAnswer);
System.out.println("");
//x++;
while( x < numQuestions + 1 );
System.out.println("");
System.out.println("Thanks for playing! Your score was " + score +
".");
【问题讨论】:
【参考方案1】:您正在专门挑选有 提醒的号码。您可以在有提醒时循环播放:
while (num1 % num2 != 0);
但是,您根本不需要循环。如果你选择第二个操作数和答案,你可以计算第一个操作数:
num2 = (int) (Math.random() *10);
compAnswer = (int) (Math.random() * 10);
num1 = num2 * compAnswer;
