The powerful programming language 'C' is closely linked to the UNIX operating system. The majority of the UNIX operating system is written in the C programming language.

'C' programming was first restricted to the UNIX operating system, but as it gained popularity around the world, it became commercial, and various compilers for cross-platform systems were created. C is now available for a wide range of operating systems and hardware platforms.

C - Home & Overview

Introduction to C programming, its history, features, and why it remains essential in modern development.

Environment Setup

Setting up the C development environment - compilers, IDEs, and running your first program.

Program Structure

Understanding the basic structure of a C program: headers, main function, and code blocks.

Basic Syntax

C syntax rules - statements, semicolons, comments, and whitespace conventions.

Data Types

Integer, float, double, char, and void types - sizes, ranges, and usage in C.

Variables

Declaring, initializing, and using variables. Naming conventions and scope basics.

Constants

Using #define and const keyword to define fixed values in a program.

Storage Classes

auto, register, static, and extern storage classes and their effect on scope and lifetime.

Operators

Arithmetic, relational, logical, bitwise, assignment, and ternary operators in C.

Decision Making

if, if-else, nested if, switch-case statements for conditional logic.

Loops

while, for, do-while loops and loop control with break, continue, and goto.

Functions

Defining and calling functions, return types, parameters, and function declarations.

Scope Rules

Local vs global variables, block scope, and function scope.

Arrays

One-dimensional and multi-dimensional arrays - declaration, initialization, and traversal.

Pointers

Pointer declaration, dereferencing, pointer arithmetic, and pointers to arrays and functions.

Strings

Character arrays, null terminator, and standard string functions (strlen, strcpy, strcat, etc.).

Structures

Defining and using structs to group related data, nested structures, and accessing members.

Unions

Union declaration, memory sharing among members, and practical use cases.

Bit Fields

Defining bit fields within structures to control memory at the bit level.

Typedef

Creating type aliases using typedef for cleaner and more readable code.

Input & Output

Using printf, scanf, getchar, putchar for standard console I/O operations.

File I/O

Opening, reading, writing, and closing files using fopen, fclose, fread, fwrite, and fprintf.

Preprocessors

#include, #define, #ifdef, #ifndef, and macro functions - how the preprocessor works.

Header Files

Standard library headers (stdio.h, stdlib.h, string.h, math.h) and creating custom header files.

Type Casting

Implicit and explicit type conversion, and using cast operators safely.

Error Handling

Using errno, perror(), and strerror() to detect and handle runtime errors.

Recursion

Writing recursive functions, base cases, and classic examples like factorial and Fibonacci.

Variable Arguments

Using stdarg.h - va_list, va_start, va_arg, va_end for variadic functions.

Memory Management

Dynamic memory with malloc, calloc, realloc, and free - avoiding leaks and undefined behaviour.

Command Line Arguments

Using argc and argv to pass arguments to C programs from the terminal.
