CS3251 - Programming in C Important Topics (Unit-wise)
Programming in C builds the core foundation for problem solving, algorithms, and low-level programming logic used in higher-level subjects. A unit-wise preparation approach helps you understand syntax, write clean programs, and score better in both theory and practical exam topics.
Unit I - Basics of C Programming
This unit covers C language fundamentals such as program structure, tokens, and control flow. Focus on writing correct syntax and understanding how expressions and operators are evaluated.
- Decision making statements and switch case
- Looping statements: for, while, do-while
- Preprocessor directives
- Structure of a C program
- Operators and precedence
- Data types in C
- Constants, enumeration constants, and keywords
- Input and output statements with expressions
Unit II - Arrays and Strings
This unit strengthens problem-solving using arrays and string manipulation. Practice common searching and sorting programs, as these are frequently asked in C programming exams.
- Array declaration and initialization
- One-dimensional and two-dimensional arrays
- String operations
- Linear search and binary search programs
- Selection sort program
- Programs for mean, median, and mode
- Matrix operations
Unit III - Functions and Pointers
This unit is important for modular programming and memory handling. Understand function design, recursion, and pointer concepts deeply to solve application-based coding topics.
- Function declaration and types of functions
- Function prototypes
- Parameter passing methods
- Recursion and binary search using recursion
- Pointers in C
- Arrays and pointers
- Array of pointers
- Pointer arithmetic and pointer operators
Unit IV - Structures
This unit introduces user-defined data types and dynamic memory concepts used in real-world C applications. Prepare structure-related programming patterns and linked list basics.
- Storage classes
- Dynamic memory allocation
- Structures and nested structures
- Pointers with structures and array of structures
- Union
- Self-referential structures
- Singly linked list
- Typedef
Unit V - File Processing
This unit focuses on permanent data handling using files in C. Revise file modes, command line usage, and program flow for text processing and transaction-based problems.
- File concepts and types of file processing
- Sequential access files
- Random access files
- Command line arguments
- File handling programs: copy file
- File handling programs: compare files
- File handling programs: read character by character
- File handling programs: count words, lines, and characters
