Analytical Class 9

 

1. Study the following program and answer the given questions.

R$ = "CANDLELIGHTS"

FOR K=1 TO LEN(R$)

    X$ = MID$(R$, K, 1)

    IF UCASE$(X$)="A" THEN

        N = N + 1

    END IF

NEXT K

PRINT N

END

a.How many times does the loop execute?

b.List the library functions in above program.

2. Study the following program and answer the given questions.

CLS

I$ = “PRO”

L$ = “GRAM” 

U$ = I$ + L$

PRINT U$

END

a.What will be the result of U$? 

b.List the variables used in above program.

3. Study the following program and answer the given questions.

CLS

R$ = “FOOT”

P$ = “BALL” 

G$ = R$ + P$

PRINT  G$

END

a.Will the program runs if CLS is removed?

b.List the variables used in above program.

4. Study the following program and answer the given questions.

CLS

N$ = “ROSE”

O$ = “BUD” 

K$ = N$ + O$

PRINT  K$

END

a.N$ + O$ gives the result as “ROSEBUD”, what does it mean?

b.List the variables used in above program.

5. Study the following program and answer the given questions.

CLS

INPUT N

R = N MOD 2 

IF R = 0 THEN

PRINT “EVEN NUMBER”

ELSE

PRINT “ODD NUMBER”

END IF

END

a.Name the variable used in above program.

b.What will be the value of R, if N = 10?

6. Study the following program and answer the given questions. 

CLS

INPUT N

R = N MOD 2 

IF R = 0 THEN

PRINT “EVEN NUMBER”

ELSE

PRINT “ODD NUMBER”

END IF

END

a.What will happen if CLS is removed from the program ?

b.What is the meaning of  R= N MOD 2 ?
