scala案例-- 九九乘法表

本文主要是介绍scala案例-- 九九乘法表，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

要求：打出九九乘法表

object test {def main(args: Array[String]): Unit = {for (i <- 1 to 9) {    //外循环控制行数for (j <- 1 to i) {   //内循环控制列数print(s"${j} * ${i} = ${i + j}\t")}println()}}
}

结果：

1 * 1 = 2	
1 * 2 = 3	2 * 2 = 4	
1 * 3 = 4	2 * 3 = 5	3 * 3 = 6	
1 * 4 = 5	2 * 4 = 6	3 * 4 = 7	4 * 4 = 8	
1 * 5 = 6	2 * 5 = 7	3 * 5 = 8	4 * 5 = 9	5 * 5 = 10	
1 * 6 = 7	2 * 6 = 8	3 * 6 = 9	4 * 6 = 10	5 * 6 = 11	6 * 6 = 12	
1 * 7 = 8	2 * 7 = 9	3 * 7 = 10	4 * 7 = 11	5 * 7 = 12	6 * 7 = 13	7 * 7 = 14	
1 * 8 = 9	2 * 8 = 10	3 * 8 = 11	4 * 8 = 12	5 * 8 = 13	6 * 8 = 14	7 * 8 = 15	8 * 8 = 16	
1 * 9 = 10	2 * 9 = 11	3 * 9 = 12	4 * 9 = 13	5 * 9 = 14	6 * 9 = 15	7 * 9 = 16	8 * 9 = 17	9 * 9 = 18
