- 1. Compilers are crucial software tools that translate high-level programming languages into machine-readable code. They play a vital role in the software development process by converting human-readable code into instructions that can be understood by computers. Compilers analyze the code, optimize it for efficiency, and generate executable programs. They help bridge the gap between the programmer and the machine, enabling the creation of complex software applications. Understanding compilers is essential for programmers looking to optimize their code and improve software performance.
