import std.console.*
main() {
println(“The characters you entered will be returned as is. Enter q to exit:”)
try {
//读取一个字符
var ch = Console.stdIn.read().getOrThrow()
<span class="hljs-comment"><span class="hljs-comment">//判断输入的是否是字符q,如果是就退出，否则继续循环</span></span>
<span class="hljs-keyword"><span class="hljs-keyword">while</span></span> (ch !=r<span class="hljs-string"><span class="hljs-string">'q'</span></span>) {
<span class="hljs-comment"><span class="hljs-comment">//输入的字符是不是换行，如果不是就打印该字符</span></span>
<span class="hljs-keyword"><span class="hljs-keyword">if</span></span> (ch != r<span class="hljs-string"><span class="hljs-string">'\n'</span></span>) {
println(ch)
}
<span class="hljs-comment"><span class="hljs-comment">//重新读取一个字符</span></span>
ch = Console.stdIn.read().getOrThrow()
}
} <span class="hljs-keyword"><span class="hljs-keyword">catch</span></span> (e: Exception) {
println(<span class="hljs-string"><span class="hljs-string">"An error occurred:"</span></span> + e.message)
}
}
