Unit 4: Pointers & Algorithms

Deep dive into memory management and fundamental algorithms.

Topics Covered:

• Pointers Basics (1_pointers_basics.c) - Pointer declaration, dereferencing, and address-of operator
• Pointers & Arrays (2_pointers_arrays.c) - Array-pointer relationship, pointer arithmetic, arrays of pointers
• Pointers & Structures (3_pointers_structures.c) - Pointers to structures, structure pointers, accessing members
• Call by Value & Reference (4_call_by_value_reference.c) - Parameter passing mechanisms and function behaviors
• Dynamic Memory (5_dynamic_memory.c) - malloc(), calloc(), realloc(), free(); memory allocation and deallocation
• Searching Algorithms (6_searching_algorithms.c) - Linear search, binary search, and performance comparison
• Sorting Algorithms (7_sorting_algorithms.c) - Bubble sort, selection sort, insertion sort, quick sort, merge sort

---

Unit 5: File Handling & OOP Concepts

Work with persistent data storage and introduce object-oriented principles in C.

Topics Covered:

• File Handling Basics (1_file_handling_basics.c) - File operations, file pointers, fopen(), fclose()
• File I/O Operations (2_file_io_operations.c) - fread(), fwrite(), fprintf(), fscanf(); text and binary file handling
• OOP Concepts (3_oop_concepts.cpp) - Object-oriented programming principles and their application in C/C++

---

Learning Path

1. Start with Unit 1 to build a strong foundation in C syntax and basic operations
2. Progress to Unit 2 to learn program flow control and function design
3. Move to Unit 3 to work with structured data types and I/O
4. Study Unit 4 to master pointers and implement algorithms
5. Conclude with Unit 5 to learn file handling and advanced concepts

---

Prerequisites

• Basic understanding of programming concepts
• A C compiler (gcc, clang, or MSVC)
• A text editor

---

How to Use These Examples

Each file contains practical examples and exercises. To compile and run:

gcc filename.c -o output_name
./output_name

For more complex programs with multiple files:

gcc file1.c file2.c -o program_name
./program_name

---

Debugging with GDB

To debug your C programs using the GNU Debugger (gdb):

1. Compile with debug symbols:

   gcc -g filename.c -o output_name

2. Start gdb:

   gdb output_name

3. Common gdb commands:

   • run or r: Run the program
   • break or b <line_number>: Set a breakpoint at a specific line
   • break or b <function_name>: Set a breakpoint at a function
   • next or n: Execute next line (step over)
   • step or s: Step into function calls
   • print or p : Print the value of a variable
   • continue or c: Continue execution until next breakpoint
   • backtrace or bt: Show the call stack
   • quit or q: Exit gdb

4. Example debugging session:

   (gdb) break main
   (gdb) run
   (gdb) next
   (gdb) print x
   (gdb) continue

For more detailed information, refer to the gdb manual.
