In computer science, an interpreter is a computer program that directly executes instructions written in a programming or scripting language, without requiring them previously to have been compiled into a machine language program. An interpreter generally uses one of the following strategies for program execution:
Compiler software interacts with source code by converting it typically from a higher-level programming language into object code that can later be executed by the computer's central processing unit (CPU). [6] The object code created by the compiler consists of machine-readable code that the computer can process. This stage of the computing ...
An interpreter is a program that reads another program, typically as text, [4] as seen in languages like Python. [2] Interpreters read code, and produce the result directly. [8] Interpreters typically read code line by line, and parse it to convert and execute the code as operations and actions. [9]
In computer programming, a programming language implementation is a system for executing computer programs. There are two general approaches to programming language implementation: [ 1 ] Interpretation : The program is read as input by an interpreter, which performs the actions written in the program.
Execution in computer and software engineering is the process by which a computer or virtual machine interprets and acts on the instructions of a computer program.Each instruction of a program is a description of a particular action which must be carried out, in order for a specific problem to be solved.
An interpreter executes code without converting it to machine code. [2]: p2 Some interpreters execute source code while others execute an intermediate form such as bytecode. A program compiled to native code tends to run faster than if interpreted. Environments with a bytecode intermediate form tend toward intermediate speed.
In computer programming, the interpreter pattern is a design pattern that specifies how to evaluate sentences in a language. The basic idea is to have a class for each symbol ( terminal or nonterminal ) in a specialized computer language .
In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers, machine code is the binary representation of a computer program which is actually read and interpreted by the computer. A program in machine ...
