main( main(

int int
int arr[ int
ptr=arr; void *vptr=ptr;


printf("the values are
vptr);

6. Discuss the following with suitable examples
i. Array of pointers ii. Pointer to function
List the functions used for various memory allocations supported by C and give one example for
each.
UNIT IV
7. Discuss how structures and unions are declared, initialized and its members accessed.
Write short note on the following
i. typedef ii. enumerations iii. bit fields
8. Develop a C program which does the following:
Define a structure 'student' with details like student name, marks for 3 subjects and total marks.
Read marks for 3 subjects of students. Calculate the total mark of each student and store
them. Display the details of the student who scored the highest marks.
Give a typical example for nested structures, arrays of structures, and arrays within structures.

UNIT V
9. Discuss the following file handling functions with suitable examples.
i. fread() ii. fwrite() iii. fseek() iv. ftell()
Develop a C program to create two files STD-DETAILS (Student Name, Student ID, and
Semester) and STD-MARKS (Sub1, Sub2, and Sub3). Concatenate the two files and display
the contents from the concatenated file
10. Discuss the primary advantages of using a data file. Describe various file operations and demonstrate
the various file accessing modes.
A file named DATA contains a series of integer numbers. Code a program to read these
numbers and then write all numbers to a file to be called ODD and all numbers to
a file to be called EVEN.
