Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. Discuss the concept of implicit type conversion with a suitable example.
Write a C program that calculates and prints the average of entered integers. Assume the user
will enter control-d to end the input.
Sample Run:
Enter an integer (control-d to 23
Enter an integer (control-d to 123
Enter an integer (control-d to 45
Enter an integer (control-d to 987
Enter an integer (control-d to 87
Enter an integer (control-d to 098
Enter an integer (control-d to
The average is 227.17
2. A palindrome is a number or a text phrase that reads the same backwards as forwards. Write a
C program that reads in a five-digit integer and determines whether or not it is a palindrome.
Hint: Use the division and modulus operators to separate the number into its individual digits.
Sample Run
Enter a five-digit number: 12345
12345 is not a palindrome
Sample Run
Enter a five-digit number: 12321
12321 is a palindrome
Discuss the concept of identifiers and data-types in C.
UNIT II
3. With a suitable example, discuss the following categories of user defined functions in C
i. functions with arguments and return values
ii. function with no argument and return type
Explain briefly how do you pass a 2D array as a parameter in
Page 1 of 2
4. The factorial of a integer denoted by is the product of all positive integers less than or
equal to N. Factorial does not exist for negative numbers and factorial of 0 is 1. Write a recursive
routine to compute factorial of a number. Write a test driver for the same.
What is an array? How is an array declared and initialized?
UNIT III
5. Bring out the significance of pointers to void with a suitable example.
In a string can be referred either using a character pointer or as a character array. Explain it
with examples.

6. Explain briefly pointer arithmetic in C with suitable examples.
What are the unformatted string input and output functions available in Is the input function
safe? If yes, why and If no, Justify?
UNIT IV
7. With a suitable example explain the concept of typedef.
A complex number is a number that can be expressed in the form a bi, where a and b are real
numbers and i is the imaginary unit, satisfying the equation i2 −1. Write a C Program to add
two complex numbers by passing structure to a function.
8. Write a C program using nested structures to read 3 employees details with the following fields;
emp-id, name, designation, address, basic, da, hra and calculate gross salary of each employee.
(Hint gross salary basic da hra).

Bring out the advantage of using Bit Fields in C with a suitable example.
UNIT V
9. Why is fseek() preferred over rewind() in
Write a C Program to Copy Contents of one file to another file.
10. Discuss how reading and writing w.r.t binary file done in C.
Explain briefly fgets() and fputs() with an example.
