为什么乘法不适用于 Read-Host 值 [英] Why does multiplication does not work with Read-Host value

问题描述

$table_num = Read-Host -Prompt 'Enter the table number you want to get printed'
for ($i=1; $i-lt 11; $i++){
    $ans = ($table_num*$i)
    write "$table_num*$i=$ans"
}

以上是我尝试执行的脚本，结果如​​下:

Above is the script which I was trying to execute and I get the result as below:

Enter the table number you want to get printed: 5
5*1=5
5*2=55
5*3=555
5*4=5555
5*5=55555
5*6=555555
5*7=5555555
5*8=55555555
5*9=555555555
5*10=5555555555

我不熟悉脚本编写并帮助我编写代码.

I am new to scripting and help me with my code.

推荐答案

感谢您的解答！！

实际上我已经添加了数据类型int.脚本如下所示.

Actually I have added the data type int. And the script is good as below.

$table_num = Read-Host -Prompt 'Enter the table number you want to get printed'

        For ($i=1; $i-lt 11; $i++){
        $ans = ([int]$table_num*$i)
            write "$table_num  *  $i =  $ans"
        }
