$("#page2").load("include_1.html");

这段代码使用 jQuery 中的 `load()` 方法来加载一个外部文件 `include_1.html` 并将其内容插入到具有 id 为 `page2` 的元素中。

假设你有以下的 HTML 结构：

<div id="page2"></div>

当执行 `$("#page2").load("include_1.html");` 这段代码时，jQuery 将会发送一个 AJAX 请求去获取 `include_1.html` 文件的内容，然后将其插入到具有 id 为 `page2` 的元素中。

请确保你已经引入了 jQuery 库，并且该代码在 DOM 加载完成后执行，以确保能够正确执行。另外，需要注意的是，如果 `include_1.html` 文件不在同一个域中，可能会遇到跨域问题。

Write a program to simulate a process of translation from a logical address to physical address. Assumptions 1. Assume the file la.txt includes the sequence of generated addresses from CPU. 2. Use a part of memory as backing store that store data for a process. 3. The backing store size is 128 bytes 4. The size of process p is 128 bytes. 5. The contents of p is included in a file pdata.bin which is a binary file. 6. Use a part of memory as RAM. The size of physical memory is 256 bytes, from 0 to 255. All the physical memory is available, allocating starting from beginning in sequence. That is, allocate frame 0 first, then frame 1, then frame 2…. 7. The size of a frame is 32 bytes, i.e., 5 bits for the offset in a frame, total number of frames is 8. 8. At beginning, no page table is available for process p. Requirements Write a program to 1. Setup a simulating backing store in memory. Read the data from pdata.bin to this backing store. 2. Initialize a page table for process p, set the frame number to be -1 for each page, indicating that the page is not loaded into memory yet. 3. Read logical addresses one by one from la.txt. 4. For each logical address, a) if its page has been loaded into physical memory, simply find the frame number in the page table, then generate physical address, find and print out the physical address and data inside this address. b) if the page is used for the first time, i.e., in page table, its frame number is -1，then the page that contains this address should be loaded into a free frame in physical memory (RAM). Then update the page table by adding the frame number to the right index in the page table. Then repeat 4a). Refer to Figure 1 for the relationships and how physical memory, backing store, and CPU are simulated. Figure 1 How physical memory, backing store and CPU are simulated in this program assignment Hints: a) use a memory block pointed by a pointer or use an array as a simulation of backing store b) use functions fread or mmap for the binary file read. Search through the Internet for the usage of these functions. c) Use an array to simulate the memory. d) Use bit operators &, |, <<, and >> to get the bits in a logic address or form a physical address e) Use char for the type of data in the process, use unsigned char (8 bits) for the type of address. Coding & Submission 1. Using pure C to finish this program. 2. Put all the codes in one .c file named PA3_#####.c, replace “#####” as the last 5 digits of your student ID. 3. Put pdata.txt and la.txt in the same folder as PA3_#####.c, which the need .txt file can be open directly by filename instead of absolute path. 4. Submit only the .c file mentioned above.使用C语言完成

page->load(QUrl(QStringLiteral("https://maps.google.com")怎么把qt中这个google地图换成必应地图

在Qt中，如果你想将Google Maps替换成Bing Maps，你需要改变加载地图服务的URL。Bing Maps的API链接通常不是`https://maps.google.com`，而是指向Microsoft的在线地图服务。以下是使用QWebEngineView（Qt 5.x以后的版本）加载Bing Maps的示例：

// 导入所需的库
#include <QWebEngineView>
#include <QWebEngineSettings>
#include <QUrl>

void loadBingMap() {
    QWebEngineView* webView = new QWebEngineView();
    // 设置默认搜索引擎为Bing Maps
    QWebEngineSettings* settings = webView->settings();
    settings->setHttpUserAgent(QWebEngineSettings::HttpUserAgent, "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3");

    // Bing Maps API 的基础URL，可能需要注册并获取实际密钥
    QUrl bingMapsUrl(QStringLiteral("https://www.bing.com/maps/api/js?callback=BingMapsLoaded&key=YOUR_BING_MAPS_API_KEY"));

    // 加载地图URL到web视图
    webView->load(bingMapsUrl);
    
    // 假设BingMapsLoaded是你自定义的回调函数名，用于处理地图加载完成
    QObject::connect(webView, &QWebEngineView::loadFinished, this, &yourClass::bingMapsLoadedHandler);

    // 如果没有预先定义该回调，可以设置一个简单的完成标志或者显示加载中的提示
}

// 这里假设有一个处理Bing Maps加载完成的槽函数
void yourClass::bingMapsLoadedHandler(QWebEngineLoadFinishedEventArgs* args) {
    if (args->error() == QWebEngineUrlLoadError::NoError) {
        qDebug() << "Bing Maps loaded successfully.";
    } else {
        qDebug() << "Failed to load Bing Maps: " << args->errorString();
    }
}

别忘了替换`YOUR_BING_MAPS_API_KEY`为你从微软开发者中心获得的实际API密钥。
