使用srand(time(0))猜测一个范围内的数字

我的问题是…我几乎完成了我的小游戏，但我想测试一下，看看它是否与"调试作弊"一起工作，看看程序是否实际上显示了正确的数字。

我设置了srand(time(0))，这样当你玩游戏时，程序显然会使每次的数字选择不同。但是，它显然一直在生成一个不同的数字，因为系统时间在变化。

正如您在代码中看到的，我有一个名为"ANSWER"的变量，又名Range(low,high)。检查名为"guessN"的用户输入变量，看它是否与"ANSWER"匹配。如果是这样，那么程序就会说用户赢了游戏，我相信这是可行的。

问题是，当我想让程序首先显示答案时，正好是47，当我输入47时，它实际上是错误的，因为时间生成器仍然在运行，它已经变成了37。

我需要的帮助:是否有一种方法可以当前暂停生成，直到用户输入他的答案?…
