Difference between Compiler and interpreter | Compiler vs. Interpreter
Difference between Compiler and interpreter
|Compiler scans the entire program first and then translates into machine code.
|Interpreter scans and translates the program line by line to equivalent machine code.
|Compiler gives you list of all errors after compilation of whole program.
|Interpreter stops the translation at the error generation and will continue when error get solved.
|Compiler converts the entire program to the machine code when all the errors are removed, execution takes place.
|Each time the program is executed; every line is check for error and then converted into equivalent machine code.
|Compiler is slow for debugging.
|Interpreter is good for fast debugging.
|Compiler takes less execution time.
|Interpreter takes more execution time.
|Compiler is faster.
|Interpreter is slower in compare to compiler.
|If you make any modification in program you have to recompile entire program i.e. scan the whole program every time after modification.
|If you make any modification and if that line has not been scanned then no need to recompile entire program.
|No need to compile program every time (if not modified) at execution time.
|Every time program is scanned and translated at execution time.
|Compiler needs more memory than interpreter.
|Interpreter needs less memory than compiler.
