可以把一个数字转换为相应的字符。因此剩下的就只是凑其 “Hello, World!” 中每个字符的 ASCII 编码了。此时我们只使用了 `c` 这一个字母，还剩下两个字符的配额可以用来凑数字，我们随意选择了 `2` 和 `3`。 10 | 11 | 把代码的最后一行翻译成更易读的形式，则为 `STDOUT << '%c' * 13 % [72, 101, 108, 108, 111, 44,

However, this is not possible. The target type must be written when it comes to explicit type conversion. `[char]65` does give us the character `A`, but there are 4 different letters. And if we want to get a number, it's `[int] something`. footnote:[https://community.idera.com/database-tools/powershell/powertips/b/tips/posts/converting-ascii-and-characters[Converting ASCII and Characters - Power Tips - Power Tips - IDERA Community]]. 48 | 49 | === Selection of the 3 characters 50 | 51 | Then I try to find the eval function. First I found the very one `Invoke-Expression`, but that is too long. Most PowerShell commands are long. That's bad for a scripting language. Then I found that the ampersand, `&`, can execute command in a string. But it works on a single _command_, without parameters.footnote:[https://stackoverflow.com/questions/50018274/why-does-invoke-operator-and-invoke-expression-produce-different-results-for[Why does invoke operator (&) and Invoke-Expression produce different results for the same input? - Stack Overflow]] Luckily, there is an alias of `Invoke-Expression`: `iex`. 52 | 53 | === The first digit 54 | 55 | Since there is no way to turn a single char into another, the only way to get a 4th character is to split a String elsewhere. In PowerShell, a character quoted by either `''` or `"` is always a string, an array of chars. There is no .pop() in Powershell,footnote:[https://stackoverflow.com/questions/24754822/powershell-remove-item-0-from-an-array[PowerShell Remove item 0 from an array - Stack Overflow]] so we need to access it by index if we want a specific character. 56 | 57 | [source,powershell] 58 | ---- 59 | $i = $? + $? 60 | ---- 61 | 62 | - $? contains the execution status of the last command.
