C Programming (Basic to Advanced)

Learn C from basics to advanced concepts including data types, operators, control flow, arrays, strings, pointers, memory management, structures, file handling, and real-world C projects.

Chapters

Overview of C Programming

Introduction to C programming language including history, evolution, features, importance, and applications of C.

Basic Structure & Fundamentals

Structure of a C program, compilation process, execution flow, tokens, keywords, identifiers, variables, constants, data types, input-output functions, and comments.

Operators & Expressions

Different types of operators in C, operator precedence and associativity, implicit and explicit type conversion and casting.

Control Flow in C

Decision making statements such as if, if-else, switch and looping constructs including for, while, do-while with jump statements.

Arrays & Strings

One-dimensional, two-dimensional and multidimensional arrays, common array operations, string handling and standard string functions.

Functions in C

Concept of functions, function declaration and definition, call by value, call by reference, and recursive functions.

Storage & Memory Concepts

Storage classes, memory layout of C programs, stack and heap memory, memory leaks, and basic debugging concepts.

Pointers

Pointers fundamentals, pointer arithmetic, pointers with arrays, strings, functions, and special pointers like void, wild and dangling pointers.

User-Defined Data Types

User-defined data types including structures, nested structures, unions, enumerations, and usage of typedef keyword.

Dynamic Memory Management

Dynamic memory allocation using malloc, calloc, realloc, and proper memory deallocation using free.

File Handling in C

Basic file handling concepts, file modes, reading and writing files, and file positioning functions like fseek, ftell, and rewind.

Preprocessor & Modular Programming

C preprocessor directives, macros, header files, modular programming concepts, and inline functions.

Command-line & Error Handling

Command-line arguments, error handling mechanisms using errno and perror functions.

Data Structures Overview (C-Based)

Introduction to data structures implemented in C including linked lists, stack, queue, circular queue, and basic tree concepts.

Additional Concepts

Advanced and supporting concepts including bitwise operators and low-level operations.

Interview & Projects

C programming interview questions, problem-solving practice, and mini projects for real-world application.
