(j) Read the following recursive program and answer the questions below:
int f(5nt kjnt m)
{
ff (k >= m) return 0; else {f (m%k == 0) return 1; else return ffk+t p m);
}
What is the output on inputs k = 5 and m = 9 ?

2, What is purpose of switch statement ?
Summarize the syntax rule associated with the use of the switch statement. 4
(b) Write a C program lhat will generate a table of values for the equation :
f(x,y) = 2ex y3 + (23 + y f
where 1 x < 20 with an increment 1 and 1 s y < 5 with araiincrementO.25.

3y (a) Explain the structure of the hard disK. Discuss the characteristics of hard disk storage. 5
(b) Write a main function that tests odd_sumQ by reading an integer from the keyboard and If the integer is positive. odd_sum() should be called and the returned value is written on th e screen, 5
4. (a) Write a program that will generate an array oflO integer numbers from 0 to 30 using the function rand() present in stdUb.h library, 5
Jb/ Explain the role of memory in computer system. What are the most common type of computer memory and memory technology used ? 5
5. (a) Write a logical function sorted in1 C that * receives an array of ht values amid in representing Ihe number of values, The
function wiH return 1 if the array values are sorted in increasing order, 0 otherwise,
5
(b) Using array declaration for Fibonacci series, write a C program to generate first n terms. 5
6. Define a structure consisting of two floating point members, called raa/and imaginary Indude the tag complex within the definition, 5
(b) Write a function in C that takes a string as the single parameter and returns the integer 1 iMhe string is a palindrome. Otherwise zero should be returned. 5
7. /a) How an array of structure is Initialized ?
/ How Is a structure member accessed? How can a structure member be processed ? Explain with relevant example. 5
r
! (b) Write the function oddsumf) in C with
j f unction head
intodd=sum(SnT n)
The function should return Ifte sum of all odd numbers between 1 and n (including 1 and n), and you1 may assume that n>=i),
5
S. (a) Explain what the recursive function below does. Do nol describe, row by row, what the function does, raiher you should explain what problem, the function solves.
void seeretffnt number)
{
assert{n umber >= D); if (number)
seer et( number); printfCd", number%2);
}
Illustrate your explanation by showing what happens wheir> the function Is called by secret (12)? 5
(b) What is a structure ? What is a structure member ? Wlhal is the relationship be twee n a structure member and a structure ?
