Answer / sahim

compiler and interpreter is same thing but a little difference
between both compiler is compile our program at a time but interpreter check our program line by line.

Answer / charulata

1: A compiler generally takes source code and turns it into
instructions that run on the hardware directly.
4: A compiler searches all the errors of a program and
lists them. If the program is error free then it converts
the code of program into machine code and then the program
can be executed by separate commands.
1: An interpreter generally processes the source code
directly or first tokenizes it into a byte-code type form
to interpret that.
2: An interpreter checks the errors of a program statement
by statement. After checking one statement, it converts
that statement into machine code and then executes that
statement. The process continues until the last statement
of program occurs.

#Compiler produce the object code and interpreter doesn't
produce the object code

Answer / krishna gavidi

compiler compile the source code while interpreter compile
the code that is allready compiled that is in the form of
bytecode
compiler scan whole code at once so it is fast incompare
with interpreter while interpreter comiled the byte code
line by line and convert in machine code so it is slow in
compare with compiler

Answer / sushant tambad

compiler:translates the entire program.
interpreter:translates the program line by line.
compiler:requires more main memory.
interpretor:requires less memory.
compiler:converts the entire program to machine code,where all the syntax error are removed and executes the machine code.
interpretor:each time the program is executed every line is checked for syntax then converts to equivalent object code directly.
compiler : execution time is less
interpretor: execution time is more

Answer / avm

interpreter is one type of compiler it convert machine code
to byte code in java only

Hello, I have PROC SQLs results group by 3 fields and I use SUM and COUNT functions in SQL. The problem is when I try to display my result with PROC TABULATE. I am getting very big numbers. I believe I make a mistake some where in Tabulate. Here is my Proc Tabulate. PROC TABULATE DATA=OUT04_05 FORMAT=12.; CLASS YR CENTRE VISA / PRELOADFMT EXCLUSIVE; VAR NEWUSER FRAUD TRANSFER AUTUSER REISSUE; TABLE CENTRE ALL, (YR ALL)*VISA, (NEWUSER*F=COMMA12. AUTUSER*F=COMMA12. FRAUD*F=COMMA12. TRANSFER*F=COMMA12. REISSUE*F=COMMA12.) / MISSTEXT={LABEL='0'} PRINTMISS RTS=20; FORMAT VISA VISAFMT.; KEYLABEL SUM = ' ' ALL = 'TOTAL'; LABEL YR = 'DATE YEAR' NEWUSER = 'TOTAL NEW ACCT' TRANSFER = 'TOTAL TRANSFER' FRAUD = 'TOTAL FRAUD TRANSFER' AUTUSER = 'TOTAL AUTH USERS' REISSUE = 'TOTAL REISSUE'; When I code it like : NEWUSER*N*F=COMMA12. AUTUSER*N*F=COMMA12. I get same amount numbers but to find a NEWUSER I use COUNT(*) and to find AUTUSER I use SUM(xxxx) function so both result shouldn’t be the same my problem is in this point. Could you tell me where the problem in code is. How can I display my result? TX.
