Article Introduction：register 关键词在 C 语言中用于将变量存储在 CPU 寄存器中，以提升访问速度。它通过在变量类型前添加 register 声明，优点在于访问寄存器比内存更快，但使用时需要注意：并非所有变量都能存储在寄存器中，编译器会根据需要优化，函数调用可能使寄存器变量丢失，且代码可移植性可能降低。因此，一般不建议显式使用 register，现代编译器会自动优化寄存器使用。

Article Introduction：The register keyword is a compiler directive used to store variables in CPU registers instead of memory. It can improve performance and save memory space, but the compiler will decide whether to store the variable in a register, and the variable must meet certain conditions, such as high frequency of use and data type as integer or pointer. Excessive use of the register keyword will reduce performance, and it does not support floating-point type variables.

Article Introduction：In C language, the register keyword prompts the compiler to store variables in CPU registers to improve access speed. It is suitable for frequently accessed small variables (such as integers or floating point types) whose scope is limited to one function. Although the compiler ultimately decides whether to store variables in registers, register can speed up access to local variables and reduce the number of memory accesses. When using it, consider register limit limits, avoid using it for large variables or shared variables, and enable compiler optimization options to support register allocation.

Article Introduction：Register variables tell the compiler to store the variable in a CPU register instead of in memory. Frequently used variables are kept in registers, where they have faster accessibility. We can never get the addresses of these variables. Register variables are declared using the "register" keyword. Scope - they are local. Default value - The default initialization value is garbage. Lifetime - until the execution of the block in which it is defined ends. The following is an example of a register variable in C: Example Demonstration #include<stdio.h>intmain(){ regist

Article Introduction：Docker is a very popular containerization solution that allows developers to package applications and their dependencies into a portable container, thereby simplifying application deployment and maintenance. In Docker, an image is the basis of the container runtime. It is a software package that can be deployed and run independently, which contains all the dependencies and configuration information of the application. But what if we want to see which images are in the Docker registry? This article will introduce how to use Docker register to view Docker
