“Who translates program language into machine language?”

"A compiler converts high-level programming language code into machine language enabling computers to execute instructions. This software tool translates entire programs at once optimizing code for efficiency and performance. Compilers are essential in software development supporting languages like C++ and Java by generating executable files. Their role ensures compatibility between human-written code and hardware facilitating complex applications in technology from operating systems to apps. By streamlining code execution compilers underpin modern computing enabling developers to create robust efficient software solutions for diverse industries."
