输入：

// 打印99乘法表
for i := 1; i < 10; i++ {
    for j := 1; j <= i; j++ {
        fmt.Printf("%d * %d = %d\t", j, i, i*j)
    }
    fmt.Println("\t")
}

输出：

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

思考题

• 作用域不一样

  练习题

  func print9X9() {
  for i := 1; i <= 9; i++ {
      for j := 1; j <= i; j++ {
          fmt.Printf("%d x %d = %-5d ", j, i, i*j)
      }
      fmt.Println()
  }
  }
