Difference between compiler and interpreter is:

The difference between compiler and interpreter is :

  

COMPILER	INTERPRETER
1)      A compiler translate the entire source program into object program in a single attempt and then only object program is executed.	1)      An interpreter translates one program instructions at a time.
2)      Compiler is faster than interpreter ( 5 to 25 times faster than interpreter )	2)  Interpreter  is slower than compiler
3)      Compiler is complex program i.e larger than of interpreter	3) Interpreter is simple program i.e smaller than that of compiler.
4)      Compared to interpreter  , developing compiler is difficult .	4)              4)  Compared  to  compiler , developing interpreter is easier.
5)      It occupies more memory because compiler is big and complex .	5) It occupies less memory as it is small and  simpler  than compiler
6)      Compiler make a bit difficult and slower to detect and correct syntax error.	6) Interpreter easily detects and reports the    error at each line .
7)      The compiled program (called object code) is permanently saved in hard disk for further use, program need not to be recompiled for execution next time.	7) Translation provided by interpreters is not preserved so , the program needs retranslation every time for execution.
8)       Examples : c, c++, FORTAN	8)      Example : QBASIC , PERL
