• Differentiate between implicit and explicit type casting.
• Explain operator precedence and associativity with examples.

Chapter 2: Input/Output and Control Structures

• What is formatted and unformatted I/O?
• What is a conditional (ternary) operator?
• Differentiate between while loop and do-while loop with examples.
• Explain nested loops with a pattern printing program.
• Write a program to print patterns using loops (star/number patterns — asked almost every year).
• Explain break, continue, and goto statements.
• Explain switch statement. Is break mandatory in switch?
• Write a program to find whether a number is prime or composite.

Chapter 3: Functions, Arrays, and Strings

• Define recursion.
• What is call by value?
• Write syntax for declaring an array.
• Differentiate between call by value and call by reference with example .
• Explain recursion with a Fibonacci series or factorial program.
• Write a program to search an element from an array.
• Write a program to find the sum of two matrices using 2D arrays.
• Describe any 3 string handling functions with examples (strlen, strcpy, strcmp, strcat, strrev).
• Explain arrays and functions together with a program.
• Write a program to sort an array (bubble sort or selection sort).
• Write a C program for matrix multiplication using 2D arrays. Explain how arrays and functions work together.
• Write a program to find x^y using recursive function.

Chapter 4: Structures, Unions, and Enumerations

• What is a structure?
• Differentiate between structure and union.
• Explain structures in C. How are arrays of structures used?
• Explain nested structures with example.
• Design a structure for student records (name, roll, marks) and write a program to store and display data for 5 students.
• Write a program using structure to store employee/student data and display records based on a condition (marks > 250, age between 30–50, etc. — varies each year but concept is same).
• Create a structure for Book (ISBN, title, author, price) and sort records based on a field.

Chapter 5: Pointers and Memory Management

• Define pointer.
• What is dynamic memory allocation?
• Explain how pointer variable changes the value of a normal variable.
• Explain null pointer and void pointer with examples.
• What is DMA? Why is it used instead of arrays?
• Explain malloc(), calloc(), and free() with examples
• Write a program using pointers and structures to store and sort records (cricketers, employees, books, etc.).
• Write a program to find minimum and maximum of N numbers using DMA.
• Write a program to store ages of students and count those within a range using DMA.

Chapter 6: File Handling, Command-Line Arguments, and Graphics

• What is a file in C?
• What is a command-line argument?
• Name any one graphics function.
• Differentiate between binary file and text file.
• Explain file modes and standard I/O functions (fopen, fclose, fread, fwrite, fprintf, fscanf).
• Explain random file access using fseek, ftell, rewind.
• Explain command-line arguments (argc and argv) with example.
• Explain any four graphics functions in C.
• Write a C program to create a file, write data, and read it back. Explain fseek, ftell, and rewind with example
• Write a program to read integers from a file and write prime numbers to another file.
• Write a program to copy contents of one file to another.
• Write a program to draw a circle, rectangle, and output text using graphics functions
• Write a program to draw a circle at the center of the screen
