Code optimization is the process of improving the efficiency and performance of a computer program by reducing the amount of resources it consumes, such as memory, CPU, and disk space, while maintaining or improving its functionality. This can involve analyzing the algorithms and data structures used in the program, as well as optimizing the source code itself for faster execution. Code optimization is essential for improving the overall speed and responsiveness of applications, especially in resource-constrained environments such as embedded systems or mobile devices. Techniques for code optimization include loop unrolling, function inlining, and memory management strategies.
