Time complexity measures the execution time of an algorithm relative to the size of the input. Tips for reducing the time complexity of C++ programs include: choosing appropriate containers (such as vector, list) to optimize data storage and management. Utilize efficient algorithms such as quick sort to reduce computation time. Eliminate multiple operations to reduce double counting. Use conditional branches to avoid unnecessary calculations. Optimize linear search by using faster algorithms such as binary search.

HTML itself cannot read text files directly, but this functionality can be achieved through back-end programming languages ??(such as PHP, Python, Java) or front-end JavaScript technology. The backend method uses PHP's file_get_contents() function to read the content from the text file and embed it into the HTML page. The front-end JavaScript method uses the Fetch API to send a GET request to a text file on the server, then parses the response content and displays it in an HTML page.
