b. A data file "rec.txt" contains some records under the heading roll, name, class. Write QBASIC program to search a record on the basis of entered roll. If data is not found, it should display "data is not present".[4]


OPEN "rec.txt" FOR INPUT AS #1

CLS

INPUT "Enter Roll Number to Search: "; searchRoll$

found = 0

DO WHILE NOT EOF(1)

INPUT #1, roll$, name$, class$

IF roll$ = searchRoll$ THEN

PRINT "Record Found!"

PRINT "Roll: "; roll$

PRINT "Name: "; name$

PRINT "Class: "; class$

found = 1

EXIT DO

END IF

 LOOP

IF found = 0 THEN

PRINT "Data is not present."

END IF

CLOSE #1

10. Write C program to input a multi-digit number and calculate the sum of its individual digits. [4]

OR

Write C program that inputs a number and check whether the input number is Armstrong or not.

#include <stdio.h>

int main()

{

int number, sum = 0, digit;

printf("Enter a number: ");

scanf("%d", &number);

while (number != 0)

{

digit = number % 10;

sum += digit;

number /= 10;

}

printf("Sum of the individual digits: %d\n", sum);

return 0;

}

 

#include <stdio.h>

#include <math.h>

int main()

{  

int n, sum = 0, rem, temp;

printf("Enter any number: ");

scanf("%d", &n);

temp = n;

while (n != 0)

{  

rem = n % 10;

sum=sum + pow(rem, 3) ;

n=n/10;

}

if (temp==sum)

{

printf("%d is armstrong", temp);

}

else

{

printf("%d is not Armstrong”, temp);

}

return 0;

}
