interpreter
An interpreter translates high-level instructions into an intermediate form, which it then executes. In contrast, a translates high-level instructions directly into . Compiled programs generally run faster than interpreted programs. The advantage of an interpreter, however, is that it does not need to go through the compilation stage during which machine instructions are generated. This process can be time-consuming if the program is long. The interpreter, on the other hand, can immediately execute high-level programs. For this reason, interpreters are sometimes used during the development of a program, when a wants to add small sections at a time and test them quickly. In addition, interpreters are often used in education because they allow students to program interactively.
Both interpreters and compilers are available for most high-level languages. However, and are especially designed to be executed by an interpreter. In addition, , such as , use an interpreter. Every PostScript , for example, has a built-in interpreter that executes PostScript instructions.
