Mar 4, 2010 · The idea is simple: You write the program, then hand it to the compiler which translates it. Then you run the result. Interpreters. An interpreter is also a program that translates a high-level language into a low-level one, but it does it at the moment the program is run. You write the program using a text editor or something similar, and then ...
Jun 10, 2023 · An Interpreter is generally used in micro-computers. It helps the programmer to find out the errors and to correct them before the control moves to the next statement. The interpreter system performs the actions described by the high-level program. For interpreted programs, the source code is needed to run the program every time.

Sep 27, 2024 · An Interpreter is a program that translates a programming language into a comprehensible language. The interpreter converts high-level language to an intermediate language. It contains pre-compiled code, source code, etc. It translates only one statement of the program at a time. Interpreters, more often than not are smaller than compilers.
Interpreters. 1. It converts the whole program into machine code at once. It translates only one statement at a time. 2. It takes more time to analyze the source code. In other words, compile time is more. However, the overall execution time is less. It comparatively takes less time to analyze the source code.
A compiler can thus make almost all the conversions from source code semantics to the machine level once and for all (i.e. until the program has to be changed) while an interpreter has to do some of this conversion work every time a statement or function is executed. However, in an efficient interpreter, much of the translation work (including analysis of types, and similar) is factored out ...

How does an interpreter execute a program?
To create an interpreter first you need to create a lexer to get the tokens of your input program. Next you create a parser that takes those tokens and, by following the rules of a formal grammar, returns an AST of your input program. Finally, the interpreter takes that AST and interprets it in some way.
