Aug 06, 2025 pm 03:34 PMalignof is used to query the alignment requirements of types, and alignas is used to specify the alignment of variables or types. 1. alignof(Type) returns the number of aligned bytes of Type, such as alignof(int) is usually 4; 2. alignas(N) specifies the minimum alignment, N must be a power of 2, such as alignas(16) intarr[4] to ensure that the array is aligned by 16 bytes; 3. Structural alignment is determined by its maximum alignment member, and can also be customized by alignas, such as structalignas(32)Vector3 to make the overall alignment to 32 bytes; 4. Using alignas(alignof(T)) in combination ensures that the buffer is based on a specific class.

Aug 06, 2025 pm 03:32 PMThe three-way comparison of C 20 is implemented through operators, which can automatically generate ==, !=, and = comparison operations. 1. Basic usage: define operator in the class and set it to default, and the compiler will automatically generate comparison logic; 2. Custom comparison: Return three-way comparison results of the corresponding type according to the specified member (such as grade); 3. Multi-field comparison: Dictionary order comparison can be achieved through if chain or std::tie. It is recommended to use members directly to improve performance; 4. Return types include std::strong_ordering, std::weak_ordering and std::partial_ordering, respectively, suitable for fully ordered, weak equivalents and possible NaN generation.

Aug 06, 2025 pm 03:28 PMCreate a responsive card grid using CSSGrid can be achieved through the following steps: 1. Set the container to display:grid, and use gap and padding to define the spacing; 2. Use grid-template-columns:repeat(auto-fit,minmax(250px,1fr)) to automatically adapt the number of columns to ensure that each column has a minimum width of 250px and equally divided the remaining space; 3. Style the.card class, set the background, rounded corners, shadows and hover effects without manually setting the width; 4. Optionally use media query to accurately control the number of columns at different breakpoints, such as 2 columns above 600px, 3 columns above 900px, and 4 columns above 1200px; 5

Aug 06, 2025 pm 03:25 PMThe core of placementnew is to construct objects on allocated memory, and the destructor needs to be called manually without releasing the memory. 1. Use alignas and sizeof to ensure memory alignment and sufficient space; 2. Use new(buffer)Type() to construct objects in the specified memory; 3. After use, explicitly call obj->~Type() to destruct; 4. Do not use delete on placementnew object to avoid crashes caused by freeing stack memory; 5. Commonly used in object pools, custom memory management and other scenarios where memory location and performance need to be controlled. For example, in the ObjectPool example, the object life cycle is managed through acquire and release to ensure

Aug 06, 2025 pm 03:19 PMTo realize automatic playback of HTML videos, you must use the autoplay attribute and add the muted attribute to comply with the browser policy. 1. Use the autoplay attribute to make the video automatically play when it is ready; 2. Add the muted attribute to avoid being blocked by the browser due to sound; 3. Add the playsinline attribute to ensure that videos are inline played on iOS devices without full screen; 4. Avoid relying on automatic playback to display key content, consider the user experience, and reduce unnecessary interference. The final solution must include both autoplay, muted and playsinline to run reliably in modern browsers.

Aug 06, 2025 pm 02:59 PMSFINAE implements conditional arrangement of template overload through std::enable_if. 1. Enable the first process function when T is an integer, 2. Enable the second process function when T is a floating point type, 3. Use type characteristics to judge the condition, and if the replacement fails, it will be removed from the candidate set without an error. Finally, the correct overload is selected according to the parameter type. This mechanism is widely used in generic programming in C 11 to C 17 until C 20 is gradually replaced by Concepts.
