Q. 3.    a.  Draw flow chart

            b.  10    INPUT A,B,C,

                  20    SUM= A+B+C

                  30    AVG=SUM/3

                  40    PRINT A,B,C,AVG

                  50    GOTO 10

                  60    END

Q.4.           10    INPUT T

                  20    IF T>=-30 AND T<=55 THEN GOTO 50

                  30    PRINT “INVALID”

                  40    GOTO 90

                  50    IF T<0 AND T>-30 THEN PRINT “VERY COOL”

                  60    IF T>0 AND T<10 THEN PRINT “COOL”

                  70    IF T>10 AND T<30 THEN PRINT “PLEASANT”

                  80    IF T>30 AND T<55 THEN PRINT “HOT”

                  90    END

Q. 5.   a.    There is no need of loop because problem doesn’t involve any repetition instruction.

           b.    10    CLS

                  20    DIM P$(15)

                  30    FOR T=1 TO 15

                  40    INPUT P$(T)

                  50    NEXT T

                  60    FOR I=1 TO 15

                  70    FOR J=2 TO 15

                  80    IF P$(I) > P$(J) THEN SWAP P$(I),P$(J)

                  90    NET J

                  100 NEXT I

                  110 FOR M=1 TO 15

                  120 PRINT P$(M)

                  130 NEXT M

                  140 END

            c.   Draw a flow chart.
