5. Write down the output of the given program. Show with a dry run in the table.

DECLARE SUB SHOW (A)

CLS

N = 87

CALL SHOW (N)

END

SUB SHOW (A)

DO

B= A MOD 6 +3

IF B MOD 4 = 0 THEN GOTO AA

PRINT B;

AA:

A=A-10

LOOP WHILE A >= 50

END SUB

Ans:

Loop No.	A	B = A MOD 6 + 3	Condition (B MOD 4 = 0)	Action	New A	Output

1st

87

87 MOD 6 + 3 = 3 + 3 = 6

False

Print 6

77

6

2nd

77

77 MOD 6 + 3 = 5 + 3 = 8

True

Skip Print

67

3rd

67

67 MOD 6 + 3 = 1 + 3 = 4

True

Skip Print

57

4th

57

57 MOD 6 + 3 = 3 + 3 = 6

False

Print 6

47

6

Output is: 6 6

6. Re-write the given program after correcting the bugs: [2]

REM to add record in an existing file
CLS
OPEN “Record.Dat” FOR OUTPUT AS #1
AA:
INPUT “Enter Name, Class and Roll No. “; Nm$, Cl, Rn
INPUT #2, Nm$, Cl, Rn
INPUT “More records “; Y$
IF UCASE$(Y$) = “Y” THEN
GOTO aa
CLOSE “Record.dat”
END

Program after correcting bugs is:

CLS
OPEN “Record.Dat” FOR APPEND AS #1
AA:
INPUT “Enter Name, Class and Roll No. “; Nm$, Cl, Rn
WRITE #1, Nm$, Cl, Rn
INPUT “More records “; Y$
IF UCASE$(Y$) = “Y” THEN
GOTO aa
end if
CLOSE #1
END

7. Study the following program and answer the given questions: [2]

OPEN “Detail.dat” FOR INPUT AS #1
OPEN “Temp.dat” FOR OUTPUT AS #2
INPUT “Enter name of the students “; Sn$
FOR I = 1 TO 10
INPUT #1, Nm$, Cl, A
IF Sn$ < > Nm$ THEN
WRITE #2, Nm$, Cl, A
END IF
NEXT I
CLOSE #1, #2
KILL “Detail.dat”
NAME “Temp.dat” AS “Detail.dat”
END

1. What is the main objective of the program given above?
The main objective of the given program is to delete the record associated with the name entered by the user.

2. Do you get any problem in the above program if the “Kill” statement is removed? Give reason.
Since the KILL statement will delete data file named “detail.dat”, if we remove KILL the new data file “temp.dat” will not be renamed as “detail.dat”

Group ‘C’ [4×4=16]

8. Convert / calculate as per the instruction: [4]

a. (10110)₂ ÷ (101)₂

Q= 100
R= 10

b. (11001101)₂ = (?)₁₆

Ans:

1100 / 1101 (simply separate in 4 digit part, follow right to left while separating numbers and add 0 if first number have not 4 digit)

Now, 1100 is C and 1101 is D

Hence, (11001101)₂ = (CD)₁₆

c. (524)₁₀ = (?)₂

Division by 2	Quotient	Remainder(Digit)	Bit #
(524)/2	262	0	0
(262)/2	131	0	1
(131)/2	65	1	2
(65)/2	32	1	3
(32)/2	16	0	4
(16)/2	8	0	5
(8)/2	4	0	6
(4)/2	2	0	7
(2)/2	1	0	8
(1)/2	0	1	9

(524)₁₀ = (1000001100)₂

d. (1010)₂ x (110)₂ – (1011)₂ = (?)₂

Step 1: Binary Multiplication

We need to multiply (1010)₂ and (110)₂.

Perform the multiplication as follows:

  1010
×    110
---------
    0000     (1010 × 0)
   10100     (1010 × 1 shifted left)
+ 101000     (1010 × 1 shifted left twice)
---------
  111100

So, (1010)₂ × (110)₂ = (111100)₂.

step 2: Binary Subtraction

Now, subtract (1011)₂ from (111100)₂.

We need to convert (1011)₂ into 6 bits for easy subtraction: (1011)₂ = 001011.

Now perform the binary subtraction:

111100
-  001011
---------
   110001

So, (111100)₂ – (1011)₂ = (110001)₂.

Final Answer:

(1010)₂ x (110)₂ – (1011)₂ = (110001)₂

9. a. Write a program in QBASIC that asks for the length, breadth, and height of a room and calculates its area and volume. Create a user-defined function to calculate area and a sub-program to calculate volume. Hint: [A = LxB], [V = LxBxH] [4]

CLS
DECLARE FUNCTION area(l, b)
DECLARE SUB volume(l, b, h)
INPUT "Enter length breadth and height: ", l, b, h
x=area(l, b)
PRINT "Area is: "; x
CALL volume(l, b, h)
END
FUNCTION area(l, b)
a=l*b
area=a
END FUNCTION
SUB volume(l, b, h)
v=l*b*h
PRINT "Volume is: "; v
END SUB

b. A sequential data file called “Record.txt” has stored data under the field heading Roll No., Name, Gender, English, Nepali, Maths, and Computer. Write a program to display all the information of those students whose gender is ‘F’ and who obtained marks on the computer more than 90. [4]

OPEN “Record.txt” FOR INPUT AS #1
CLS
PRINT “Roll No”, “Name”, “Gender”, “English”, “Nepali”, “Maths”, “Computer”
WHILE NOT EOF(1)
	INPUT #1, r, n$, g$, e, n, m, c
	g$ = UCASE$(g$)
	IF g$ = “F” AND c>90 THEN
		PRINT r, n$, g$, e, n, m, c
	END IF
WEND
CLOSE #1
END

10.  Write a program in C language that asks a number and check whether it is odd or even. [4]

#include <stdio.h>
int main() {
    // Declare a variable to store the number
    int number;

    // Prompt the user to enter a number
    printf("Enter a number: ");
    scanf("%d", &number);

    // Check if the number is even or odd
    if (number % 2 == 0) {
        printf("%d is an even number.\n", number);
    } else {
        printf("%d is an odd number.\n", number);
    }
    return 0;
}

OR

Write a program in ‘C’ language to display the series with their sum. 1,2,3,4,….., up to 10th terms.

#include <stdio.h>
int main() {
int sum = 0;

printf(“The series is: “);
for (int i = 1; i <= 10; i++) {
printf(“%d “, i);
sum += i;
}
printf(“\nThe sum of the series is: %d\n”, sum);
return 0;
}
