📚 Full C Programming Syllabus with Definitions & Structure

This guide offers a complete breakdown of the C programming language syllabus — from fundamentals to advanced concepts — including definitions, structures, and topic outlines. Ideal for beginners and intermediate learners.

---

🧾 1. Introduction to C

• What is C?: A general-purpose procedural programming language developed by Dennis Ritchie in 1972.
• Features of C: Fast, portable, low-level access, modular, statically typed.
• Structure of a C Program:

#include <stdio.h>  // Preprocessor Directive
int main() {        // Main Function
    printf("Hello, World!\n"); // Statement
    return 0;       // Return Statement
}

---

🔤 2. Basic Syntax

• Tokens: Keywords, Identifiers, Constants, Strings, Special Symbols
• Semicolon and Braces
• main() function, printf() and scanf()

---

🔣 3. Data Types and Variables

• Data Types: int, float, double, char, void
• Modifiers: short, long, signed, unsigned
• Variable Declaration and Initialization

---

🧮 4. Operators and Expressions

• Arithmetic Operators: +, -, *, /, %
• Relational Operators: ==, !=, >, <, >=, <=
• Logical Operators: &&, ||, !
• Assignment, Increment/Decrement, Bitwise, Ternary

---

🔁 5. Control Flow

• Conditional Statements: if, if-else, else-if ladder, switch
• Loops: for, while, do-while
• Jump Statements: break, continue, goto, return

---

📦 6. Arrays

• 1D Arrays: Declaration, Initialization, Traversal
• 2D Arrays: Matrix-style usage
• Strings (character arrays) – covered in detail separately

---

🧵 7. Strings

• String Declaration and Initialization
• String Functions: strlen, strcpy, strcat, strcmp
• Manual Traversal and Manipulation

---

🧰 8. Functions

• Function Declaration, Definition, and Calling
• Types:
  • No arguments, no return
  • Arguments with/without return
• Recursion: Base case, recursive case

---

🗃️ 9. Storage Classes

• auto
• register
• static
• extern

Describes scope, visibility, and lifetime of variables.

---

📍 10. Pointers

• Declaration and Initialization
• Pointer Arithmetic
• Pointer to Array, Pointer to Function, Pointer to Pointer
• NULL pointer, void pointer

---

🧾 11. Structures and Unions

• Structure:

struct Student {
    int id;
    char name[50];
};

• Accessing members, nested structures, arrays of structures
• Union: Memory-efficient data structures

---

📂 12. File Handling

• File Pointers: FILE *fp
• File Operations: fopen(), fclose(), fprintf(), fscanf(), fread(), fwrite()
• Modes: "r", "w", "a", "r+", "w+"

---

⚙️ 13. Preprocessor Directives

• #include, #define, #undef, #ifdef, #ifndef, #if, #else, #endif
• Macros vs Functions

---

🧠 14. Dynamic Memory Allocation

• malloc(), calloc(), realloc(), free()
• Memory leaks and best practices

---

📊 15. Data Structures in C (Basics)

• Arrays
• Linked Lists (Singly, Doubly, Circular)
• Stack and Queue (using arrays and linked list)
• Tree (basic binary tree)
• Hashing (basic hash tables)

---

🧪 16. Miscellaneous Concepts

• Typecasting
• Command Line Arguments
• Error Handling using errno, perror, strerror
• Inline Assembly (for advanced learners)

---

📝 Sample Mini Projects

• Student Record System
• Library Management System
• Banking System
• Quiz Game
• File Encryption/Decryption

---

🏁 Conclusion

Mastering C gives a solid foundation for system programming, competitive coding, and understanding other languages like C++, Java, or Go.
