INPUT#2, Name$, C, RN
INPUT "More records"; Y$
IF UCASE$ (Y$)="Y" THEN GOTO POP:
CLOSE #2
STOP


Debugged Program
REM to add record in an existing file.

OPEN "student.dat" FOR APPEND AS #2

TOP:

INPUT "Enter any word"; A$
END
FUNCTION COUNT (A$)
B = LEN (A$)
C = 0
FOR I=1 TO B

E$=Ucase$(E$)
E$=MID$ (A$,I,1)
IF E$="A" OR E$="E" OR E$="I" E$="O" OR E$ ="U" THEN
C=C+1
END IF
NEXT I
COUNT=C
END FUNCTION

i) (1503)8 = (?)16
= (343)16
ii) (101000101)2 = (?)8
= (505)8
iii) (1010 + 1101)2- (110)2
= (10001)2
iv) (100111)2/(110)2
Q=110, R = 11

 

9. Answer the following questions:

a) Write a program in QBASIC that asks length, breadth and height of room and calculate its perimeter and volume. Create a Function procedure to calculate perimeter and Sub procedure to calculate the volume.
[HINT: Volume LxBxH and perimeter = 2(L+B)] 4
DECLARE FUNCTION Perimeter (L, B)
DECLARE SUB Volume (L, B, H)
CLS
INPUT "Enter the Length of the room: "; L

INPUT "Enter the Breadth of the room: "; B

INPUT "Enter the Height of the room: "; H

CALL Volume (L, B, H)
P=Perimeter (L, B)
PRINT "The Perimeter of the room is: "; P 
END

FUNCTION Perimeter (L, B)
Perimeter = 2* (L + B)
END FUNCTION

SUB Volume (L, B, H)
V=L*B*H
PRINT "The Volume of the room is:",V
END SUB

END IF
LOOP
CLOSE #1
END

10. Write a program in C-language to find the greatest number among any two different input numbers.

#include<stdio.h>

{

int a,b;

printf("Enter two numbers");

scanf("%d%d",&a,&b);

if(a>b)

{

printf("%d is greater than %d",a,b);

}

else

{

printf("%d is greater than %d",b,a);

}

return 0;

}
