Explain the concept of code generation and its role in reducing program complexity.

Code generation is the process of automatically generating executable code from a higher-level representation of a program, such as source code or an intermediate representation. It plays a crucial role in reducing program complexity by abstracting away low-level details and providing a more concise and efficient representation of the program.

By generating code automatically, developers can focus on writing high-level, domain-specific code rather than dealing with low-level implementation details. This abstraction allows for easier understanding and maintenance of the program, as it reduces the complexity associated with manual coding.

Code generation also enables the use of code templates or libraries, which can be reused across multiple projects. This reusability further reduces complexity by eliminating the need to reinvent the wheel and promoting standardization.

Additionally, code generation can optimize the generated code by applying various techniques, such as dead code elimination, constant folding, and loop unrolling. These optimizations improve the performance and efficiency of the program, while still maintaining the desired functionality.

In summary, code generation simplifies program development by abstracting away low-level details, promoting code reuse, and optimizing the generated code. It ultimately reduces program complexity by providing a higher-level representation of the program and improving its efficiency.
