The basic difference is that a compiler system, including a (built in or separate) linker, generates a stand-alone machine code program, while an interpreter system instead performs the actions described by the high-level program. A compiler can thus make almost all the conversions from source code semantics to the machine level once and for ...
An interpreter is computer software that transforms and then executes the indicated operations. [2]: p2 The translation process influences the design of computer languages, which leads to a preference of compilation or interpretation. In theory, a programming language can have both a compiler and an interpreter.
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 ...
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. [2]
The interpreter was used to debug a program before creating an executable file. Unfortunately, there were some subtle differences between the interpreter and the compiler, which meant that large programs that ran correctly in the interpreter might fail after compilation, or not compile at all because of differences in the memory management ...
The Computer Language Benchmarks Game site warns against over-generalizing from benchmark data, but contains a large number of micro-benchmarks of reader-contributed code snippets, with an interface that generates various charts and tables comparing specific programming languages and types of tests.
Statement separator – demarcates the boundary between two statements; need needed for the last statement Line continuation – escapes a newline to continue a statement on the next line Some languages define a special character as a terminator while some, called line-oriented , rely on the newline .
Any program written in a high-level programming language must be translated to object code before it can be executed, so all programmers using such a language use a compiler or an interpreter, sometimes even both. Improvements to a compiler may lead to a large number of improved features in executable programs.
