Where is the linux kernel source code?
Article Introduction:The location of the Linux kernel source code is generally in the "/usr/src/linux kernel version" directory in the system; if there is no similar directory in the system, it is because the kernel code has not been installed yet. The kernel is the soul of the entire operating system and is responsible for managing the disk. Files, memory, responsible for starting and running programs, responsible for receiving and sending data packets from the network, etc.

Memory management in C++ technology: Differences in memory management between managed code and unmanaged code
Article Introduction:Differences in memory management between managed and unmanaged code in C++: managed code is managed by the CLR, while unmanaged code is managed by the operating system. Memory allocation and release of managed code is automatically performed by the CLR, while unmanaged code needs to be managed manually. Managed code uses garbage collection, and unmanaged code needs to be wary of memory leaks and segfaults. Memory management for managed code is simple and safe, while unmanaged code is complex and error-prone.

The internal code of a Chinese character requires several bytes to store
Article Introduction:The internal code of a Chinese character requires 2 bytes to store. In the popular Chinese character system in China, the internal code of a Chinese character occupies 2 bytes. Because the Chinese character processing system must ensure compatibility between Chinese and Western languages, ambiguity will occur when ASCII codes and Chinese character national standard codes exist in the system. ; To this end, the Chinese character internal code should be appropriately processed and transformed into the national standard code.

How to perform memory management in C++ code?
Article Introduction:How to perform memory management of C++ code? C++ is a powerful programming language, but it also requires programmers to manage memory by themselves. Proper memory management is one of the keys to ensuring that programs run stably and efficiently. This article will introduce some common memory management techniques and best practices to help beginners and experienced developers better manage the memory of C++ code. Using stack and heap: There are two main ways of memory allocation in C++: stack and heap. The stack is a place where memory is automatically allocated and released, used to store local variables and function call information.
