我决定将第一个C程序写成一台老虎机。但是，我遇到了一些困难。
scanf("%d", decision);
if (decision == 1)
似乎无论何时使用此部件，整个程序都会崩溃。为什么？
编辑：回答。我忘了在＆＃34;决定之前加入＆符号＆＃34;。感谢大家！答案 0 :(得分：2)
您的问题来自一个简单的错误：您忘记g=sns.clustermap(matrix, col_cluster=False, linewidths=0.9, cmap='coolwarm', row_colors=row_colors)传递private def publishMessagesAttempt(producer: KafkaProducer[String, String], topic: String, messages: Iterable[(String, String)], producerMaxDelay: Long,
individualMessageMaxDelay: Long, logger: (String, Boolean) => Unit = KafkaClusterUtils.DEFAULT_LOGGER): Iterable[(String, String)] = {
val futureMessages = messages.map(message => (message, producer.send(new ProducerRecord[String, String](topic, message._1, message._2))))
val messageSentTime = System.currentTimeMillis
val awaitedResults = futureMessages.map { case (message, future) =>
val waitFor = Math.max(producerMaxDelay - (System.currentTimeMillis - messageSentTime), individualMessageMaxDelay)
val failed = Try(future.get(waitFor, TimeUnit.MILLISECONDS)) match {
case Success(_) => false
case Failure(f) =>
logger(s"Error happened when publish to Kafka: ${f.getStackTraceString}", true)
true
}
(message, failed)
}
awaitedResults.filter(_._2).map(_._1)
}
的地址而不是其值：
&请注意，可以通过提高编译器的警告级别来避免此类错误：decision，scanf("%d", &decision);
或gcc -Wall
另请注意，您应该检查clang -Weverything的返回值。如果号码已正确转换为cl /W4，则应返回scanf()。否则使用1可能会有未定义的行为。
