In summer, you must try shooting a rainbow
Jul 21, 2024 pm 05:16 PM
After rain in summer, you can often see a beautiful and magical special weather scene - rainbow. This is also a rare scene that can be encountered in photography, and it is very photogenic. There are several conditions for a rainbow to appear: first, there are enough water droplets in the air, and second, the sun shines at a low angle. Therefore, it is easiest to see a rainbow in the afternoon after the rain has cleared up. However, the formation of a rainbow is greatly affected by weather, light and other conditions, so it generally only lasts for a short period of time, and the best viewing and shooting time is even shorter. So when you encounter a rainbow, how can you properly record it and photograph it with quality? 1. Look for rainbows. In addition to the conditions mentioned above, rainbows usually appear in the direction of sunlight, that is, if the sun shines from west to east, rainbows are more likely to appear in the east.

Apr 24, 2024 pm 04:21 PM
In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

C++ Function Exception Advanced: Customized Error Handling
May 01, 2024 pm 06:39 PM
Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.

Things to note when Golang functions receive map parameters
Jun 04, 2024 am 10:31 AM
When passing a map to a function in Go, a copy will be created by default, and modifications to the copy will not affect the original map. If you need to modify the original map, you can pass it through a pointer. Empty maps need to be handled with care, because they are technically nil pointers, and passing an empty map to a function that expects a non-empty map will cause an error.
