Compiler vs Interpreter

A compiler and an interpreter are both software tools used in the process of executing code written in a programming language, but they operate in different ways. A compiler is a program that translates source code written in a high-level programming language into machine code or bytecode that can be executed directly by the computer's processor. The compiler reads the entire source code and then generates a complete executable program. Once the source code is compiled, it can be executed many times without needing to be recompiled, as long as the underlying hardware architecture remains the same. Some examples of compiled languages include C, C++, Java, and Swift. On the other hand, an interpreter is a program that reads and executes source code one line at a time. Instead of translating the entire source code into machine code, the interpreter translates each line of code into machine code on the fly and executes it immediately. This means that an interpreter can provide more immediate feedback and faster iteration during development. Some examples of interpreted languages include Python, Ruby, and JavaScript. In summary, the main difference between a compiler and an interpreter is the way they execute source code. A compiler translates source code into machine code all at once, while an interpreter translates and executes source code line by line.
