What is Interpreter?
1. Interpreter
Takes Single instruction as input .
2. No
Intermediate Object Code is Generated
3. Conditional
Control Statements are Executes slower
4. Memory
Requirement is Less
5. Every time
higher level program is converted into lower level program
6. Errors are
displayed for every instruction interpreted (if any)
7. The
interpreter can immediately execute high-level programs, thus interpreters are
sometimes used during the development of a program, when
a programmer
wants to add small sections at a time and test them quickly.
8. In addition,
interpreters are often used in education because they allow
students to
program interactively.
Examples
of Programming Languages Using Interpreter :
Lisp
(defun convert ()
(format t "Enter
Fahrenheit ")
(LET (fahr)
(SETQ fahr (read
fahr))
(APPEND '(celsisus
is) (*(- fahr 32)(/ 5 9)) )
