我想将C的outb函数移植到D.
static __inline void outb (unsigned char value, unsigned short int port)
{
__asm__ __volatile__ ("outb %b0,%w1"
:
:
"a" (value),
"Nd" (port));
}
这是D版.
extern(C)
{
void outb (ubyte value, ushort port)
{
// I couldn't figure out this part
}
}
这些是关于该主题的一些链接.
D内联汇编程序

但我不懂汇编语言,所以我需要一些帮助.任何帮助,将不胜感激.谢谢.
我将此变量添加到.env文件中
STRIPE_SECRET = A12345
我想使用routes/web.php转储变量
<?php
dd(env('STRIPE_SECRET'));
但看起来它总是返回null.
更新:更新.env文件.我只删除了DB_PASSWORD.

我有一个像这样的简单html文件.事实上,我从维基页面中删除了它,删除了一些html属性并转换为这个简单的html页面.
<html>
<body>
<h1>draw electronics schematics</h1>
<h2>first header</h2>
<p>
<!-- ..some text images -->
</p>
<h3>some header</h3>
<p>
<!-- ..some image -->
</p>
<p>
<!-- ..some text -->
</p>
<h2>second header</h2>
<p>
<!-- ..again some text and images -->
</p>
</body>
</html>
我用这样的python和漂亮的汤读了这个html文件.
from bs4 import BeautifulSoup
soup = BeautifulSoup(open("test.html"))
pages = []
我想做的是将这个html页面分成两部分.第一部分将在第一个标题和第二个标题之间.第二部分将位于第二个标题<h2>和</ body>标记之间.然后我想将它们存储在列表中,例如.页面.所以我可以根据<h2>标签从html页面创建多个页面.
关于我该怎么做的任何想法？谢谢..
考虑这段代码,它计算数组的最大元素.
#include <stdio.h>
int maximum(int arr[], int n)
{
if (n == 1) {
return arr[0];
} else {
int max = maximum(arr, n-1);
printf("Largest element : %d\n", max);
return 5; // return arr[n-1] > max ? arr[n-1] : max;
}
}
int main()
{
int array[5] = {5, 23, 28, 7, 1};
printf("Maximum element of the array is: %d", maximum(array, 5));
return 0;
}
为什么这个else块叫四(4)次？
import std.stdio;
struct Vector2
{

auto result = this;

我的模板如下所示：
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
var selectedForm = 0;
function doWork() {
var response = $('#reply1').val();
console.log(response);
$.post({url: "receiver", data: JSON.stringify({selectedForm: selectedForm, response : response}),
contentType: "application/json", success: function(){}});
}
$('.respondButton').click(function(e) {
e.preventDefault();
var selectedButton = $(this).attr('id');
selectedForm = selectedButton.replace('response', '');
console.log(selectedForm);
});
$('#submitButton1').click(function(e) {
e.preventDefault();
doWork();
});
});
</script>
html部分：
<a id="response1" href="" class="respondButton">
<span>response1</span>
</a>
<a id="response2" href="" class="respondButton">
<span>response2</span>
</a>
<form action="/receiver" method="post" id="form1" name="form1">
<textarea type="text" rows ="3" name="reply1" id="reply1"></textarea>
<button …我想将一个字符串转换为小写但如果这个字符串包含一个特殊的单词,它应该保留原样.
specialwords = ['Special1', 'Special']
假设我们的输入字符串是这样的:
Ali is really Special.
输出应该是这样的:
ali is really Special
这是我到目前为止使用的代码.
def makeUrl(inputString):
list = {"?": "i",
"I": "?",
"?": "?",
"î": "i",
"Ç": "c",
"ç": "c",
" ": "-",
"?": "s",
"?": "s",

"?": "g",
"Ü": "u",
"ü": "u",
"Ö": "o",
"ö": "o",
"!": "",
"?": "",
"'": "",
"“": "",
"”": "",
"â": "a"}
inputString = inputString.encode('utf8', 'replace')
for letter in list:
inputString = inputString.replace(letter, liste[letter])
if "Ali" in inputString:
return …
