scala生成九九乘法表

Scala代码如下：

for (i <- 1 to 9; j <- 1 to i) {
  print(j + " * " + i + " = " + (i*j))
  if (i == j) {
    println()
  } else {
    print(", ")
  }
}

这段代码使用了两个嵌套的 for 循环，分别遍历乘法表的行和列。

在循环体内部，使用 print 函数打印每个乘法表达式及其结果，并且根据是否为该行的最后一个元素，决定是否换行输出。

这样就可以在控制台中输出九九乘法表了。

scala九九乘法表

Sure! Here's an example of how you can generate a 9x9 multiplication table using Scala:

object MultiplicationTable {
  def main(args: Array[String]): Unit = {
    for (i <- 1 to 9) {
      for (j <- 1 to 9) {
        val result = i * j
        print(f"$i * $j = $result\t")
      }
      println()
    }
  }
}

When you run this program, it will print the multiplication table from 1x1 to 9x9. Each multiplication expression will be formatted as "i * j = result". The "\t" is used to add a tab space between each expression for better readability.

Feel free to give it a try and let me know if you have any further questions!

scala语言写九九乘法表

以下是使用 Scala 语言编写九九乘法表的代码：

object MultiplicationTable {
  def main(args: Array[String]): Unit = {
    for (i <- 1 to 9) {
      for (j <- 1 to i) {
        print(s"$j * $i = ${i * j}\t")
      }
      println()
    }
  }
}

输出结果如下：

1 * 1 = 1	
1 * 2 = 2	2 * 2 = 4	
1 * 3 = 3	2 * 3 = 6	3 * 3 = 9	
1 * 4 = 4	2 * 4 = 8	3 * 4 = 12	4 * 4 = 16	
1 * 5 = 5	2 * 5 = 10	3 * 5 = 15	4 * 5 = 20	5 * 5 = 25	
1 * 6 = 6	2 * 6 = 12	3 * 6 = 18	4 * 6 = 24	5 * 6 = 30	6 * 6 = 36	
1 * 7 = 7	2 * 7 = 14	3 * 7 = 21	4 * 7 = 28	5 * 7 = 35	6 * 7 = 42	7 * 7 = 49	
1 * 8 = 8	2 * 8 = 16	3 * 8 = 24	4 * 8 = 32	5 * 8 = 40	6 * 8 = 48	7 * 8 = 56	8 * 8 = 64	
1 * 9 = 9	2 * 9 = 18	3 * 9 = 27	4 * 9 = 36	5 * 9 = 45	6 * 9 = 54	7 * 9 = 63	8 * 9 = 72	9 * 9 = 81
