Answer ONE question from each Unit
All Questions Carries Equal Marks
All parts of the question must be answered in one place only
Unit – I :
1. a) Explain briefly steps in creating and running programs. 7M
b) What is a constant? Explain briefly three ways of using constants in C with a suitable example. 8M
2. a) C uses small integers internally to represent each different character. The set of characters a computer uses and the corresponding integer representations for those characters is called that computer’s character set. Write a C program that prints the integer equivalents of some uppercase letters, lowercase letters, digits and special symbols. As a minimum, determine the integer equivalents of the following: A B C a b c 0 1 2 $ * + / and the blank character. 7M
b) What is type conversion? List four situations where type conversion is done in C. 8M
Unit – II :
3. a) Explain briefly the following control structures of C:
i. Switch
ii. Do-while 7M
b) Write a C program to perform matrix addition using arrays. 8M
4. a) Define a function called hypotenuse that calculates the length of the hypotenuse of a right triangle when the other two sides are given. Use this function in a program to determine the length of the hypotenuse for each of the following triangles. The function should take two arguments of type double and return the hypotenuse as a double. 7M
b) Explain briefly command line arguments in C with a suitable example. 8M
Unit – III :
5. a) Explain predefined string handling functions with examples. 8M
b) Explain pointer arithmetic with examples. 7M
6. a) Write a C program to check wether the given string is palindrom or not? 6M
b) Describe any three functions associated with dynamic memory management in C. 9M
Unit – IV :
7. a) What are nested structures and how are they defined? Demonstrate them giving suitable example. 7M
b) Define a structure with the following fields: title of book, author name, number of pages, and publisher’s name. Write a C program to read 10 books data and print the details. 8M
8. a) What is union? Illustrate how a union member is accessed and also differentiate structure and union giving suitable example. 7M
b) Write a C program using a pointer to structure illustrating the initialization of the members in the structure. 8M
Unit – V :
9. a) Design a C program to create a file called emp.txt and store information about an employee like name, age and salary. 7M
b) What is a file? Describe the terms text file and binary file with respect to C. 8M
10. a) Explain briefly fseek() with suitable examples. 7M
b) Write a program to display file contents 20 lines at a time. The program should pause after displaying 20 lines until the user presses either Q to quit or Return to display the next 20 lines. The filename should be accepted from user and then process the file. 8M
