Compiler and interpreter are two different types of software used for programming languages. Here are the main differences between them:


FeatureCompilerInterpreter
DefinitionA software program that converts high-level programming language code into machine language (executable code) before it is run.A software program that executes code line-by-line, translating and executing each line as it is encountered.
CompilationCompiles the entire program at once into an executable file.Does not compile the entire program at once. Translates and executes one line or block of code at a time.
ExecutionThe compiled code runs directly on the computer's processor without the need for the original source code.The code is executed line-by-line and does not produce an executable file.
PerformanceCompiling code results in faster execution since the code is already translated into machine language before it is run.Interpreting code can result in slower execution since each line or block of code needs to be translated and executed as it is encountered.
DebuggingDebugging can be more difficult since the code is compiled before it is run, making it harder to trace errors back to their source.Debugging can be easier since the code is executed line-by-line, making it easier to identify errors and trace them back to their source.
ExamplesC++ compiler, Java compiler, Visual Basic compiler.Python interpreter, Ruby interpreter, Perl interpreter.
