1.WRITE AN ALGORITHM TO INPUT 100 NUMBERS AND DISPLAY THE SUM OF ODD NUMBERS
START
STEP 1 : DECLARE I , C , NUM AS AN INTEGER
STEP 2: I=1 , C=0 , NUM=0
STEP 3: INPUT "ENTER THE NUMBER", NUM
STEP 4: IF NUM %2< >0 THEN C=C+NUM
STEP 5: INCREMENT THE VALUE OF I BY 1
STEP 6: IF I<=100 THEN GOTO STEP 3
STEP 7 : PRINT "SUM OF ODD NUMBERS", C
END
1. TO INPUT 'N' DIFFERENT NUMBERS AND DISPLAY ONLY PRIME NUMBERS.
START
STEP 1: DECLARE THE VARIABLES K, J , C ,N AND NUM AS INTEGER
STEP 2: J=1 , C=0 , NUM=0 , N=0 , K=1
STEP 3: INPUT " HOW MANY NUMBERS:" ; N
STEP 4: INPUT "ENTER THE NUMBER" ; NUM
STEP 5 : IF NUM % J =0 THEN C=C+1
STEP 6 : INCREMENT THE VALUE OF J BY 1
STEP 7: IF J<=NUM THEN GOTO STEP 5 ELSE GOTO STEP 8
STEP 8 : IF C=2 THEN PRINT NUM ; "IS PRIME"
STEP 9 : C=0 , J=1
STEP 10 : INCREMENT THE VALUE OF K BY 1
STEP 11: IF K<=N THEN GOTO STEP 4
END
1. TO INPUT 20 NUMBERS AND DISPLAY THEIR SUM .
START
STEP 1: DECLARE THE VARIABLES J , C AND NUM AS INTEGER
STEP 2: J=1 , C=0 , NUM=0
STEP 3: INPUT "ENTER THE VALUE OF NUMBER"; NUM
STEP 4: C=C+NUM
STEP 5: INCREAMENT THE VALUE OF J BY 1
STEP 6: IF J<=NUM THEN GOTO STEP 3 ELSE GOTO STEP 7
STEP 7 :PRINT "SUM IS:" ; C
END
ALGORITHM :
-------------------------
1. TO INPUT A NUMBER AND CHECK WHETHER A NUMBER IS PRIME NUMBER OR NOT.
START
STEP 1: DECLARE THE VARIABLES J , C AND NUM AS INTEGER
STEP 2: J=1 , C=0 , NUM=0
STEP 3: INPUT "ENTER THE VALUE OF NUMBER"; NUM
STEP 4: IF NUM % J=0 THEN C=C+1
STEP 5: INCREAMENT THE VALUE OF J BY 1
STEP 6: IF J<=NUM THEN GOTO STEP 4 ELSE GOTO STEP 7
STEP 7 : IF C=2 THEN PRINT NUM; "IS PRIME " ELSE PRINT NUM ; "IS NOT PRIME"
END
Differences between JAVA and OS :
1. Java is an High Level Language where as OS is an System Software.
2. Java file contains a Secondary file name .java , OS contains different types of files having extentions like .Exe , .Sys etc.
3. Java needs Compiler as well as Interpreter where as OS does not required anything.
4.For Execution of Java programs, it depends on OS (without OS it can't execute), but OS does not depends on JAVA.
