Compiler

A compiler is a program that converts source code written in a high-level programming language into machine code executable by a computer.A compiler is a software tool that translates high-level programming code into machine-readable instructions. It takes source code written in languages like C++ or Java and compiles it into machine code (binary) that the computer’s processor can execute. Compilers perform several functions during this process: lexical analysis, syntax analysis, semantic analysis, optimization, and code generation. They also detect and flag errors in the source code, helping developers debug their programs. By converting human-readable code into machine-executable form, compilers act as the backbone of software development, bridging the gap between programming languages and computer hardware.
