Ans: Differentiate between select query and update query are as follows.
Select query |
Update query |
Retrieves
data from one or more tables and displays it in a result set. |
Updates
existing data in one or more tables. |
Returns a
read-only result set that displays the data matching the specified criteria |
Modifies the
existing data in the database according to the specified criteria. |
SELECT
queries do not modify the data in the database. |
UPDATE
queries are used to modify data in the database, typically to reflect changes
in the real world. |
One or more
tables are involved. |
Only one
table is involved. |

W$=we love our country
V=vowel(w$)
PRINT “The total no of vowel:”;v
END
FUNCTION vowel$(s$)
C=0
FOR k= 1 to length(s$)
B$=MID$(s$,k,1)
B$=LCASE$(b$)
SELECT CASE b$
CASE “a”, “e”,”I”,”o”,”u”

Ans:
DECLARE FUNCTION volume (l, b, h)
DECLARE SUB tsa (l, b, h)
CLS
INPUT "Enter length, breadth and height"; l, b, h
v = volume(l, b, h)
PRINT "Volume of cuboid: "; v
CALL tsa(l, b, h)
END
SUB tsa (l, b, h)
a = 2 * (l * b + b * h + l * h)
PRINT "Total surface area of cuboid: "; a
END SUB
FUNCTION volume (l, b, h)
volume = l * b * h
END FUNCTION
b) A sequential data file “records.dat” contains s.no, name, address, telephone no and email address. Write a program to count and display those records whose email address ends in “yahoo.com” domain. Your display should be in tabular format having the fields name, address and email address only. 4
OPEN “records.dat” FOR INPUT AS #1
CLS
DO WHILE NOT EOF(1)
INPUT #1, sno, name$, add$, tel, email$
IF LCASE$(RIGHT$(email$,9))=”yahoo.com” THEN PRINT name$,add$,email$
T=t+1
LOOP
PRINT “Total no of people having Yahoo.com email address are: “;t
CLOSE #1
END
10) Write a program in C language that asks a number check whether number is positive negative or zero. 4
#include <stdio.h>
int main()
{
int num;
printf("Enter a number: ");
scanf("%d", &num);
if (num > 0)
{
printf("%d is positive\n", num);
}
else if (num < 0)
{
printf("%d is negative\n", num);
}
else
{
printf("The number is zero\n");
}
return 0;
}
Write a program in C language to display the series with their sum 7 10 13 16 …….upt 10th term.
#include <stdio.h>
int main() {
int i, sum = 0, num = 7;
printf("The series is: ");
for (i = 1; i <= 10; i++)
{
printf("%d ", num);
sum =sum+num;
num =num+3;
}
printf("\nThe sum of the series is: %d", sum);
return 0;
}
