Smart Pointers in C++: unique_ptr, shared_ptr and weak_ptr Explained with Tested Code
How C++ smart pointers own memory, measured: what each one costs in bytes and allocations, why shared_ptr cycles leak, and which one to use where.
Pointers
malloc vs calloc in C: Differences, realloc, free and the Bugs That Matter
The difference between malloc and calloc in C, with measured costs, realloc and free, four heap bugs caught by sanitizers, and C++ new and delete.
Double Pointer in C (Pointer to Pointer): Complete Guide with Examples
A double pointer in C stores the address of another pointer. See the memory diagram, the key use cases, and tested examples of int** and char**.
Char Array vs String in C and C++ — char[], char*, and std::string
Why writing to one of these two identical-looking declarations crashes, what array decay does to sizeof, and what std::string changes.
Linked List in C: Complete Guide with Operations and Examples
A linked list in C chains heap-allocated nodes through pointers. Build one completely: all operations, complexity analysis and a tested full program.

Pointers in C++ — From Raw Pointers to Smart Pointers (Complete Tutorial)
A unique_ptr is 8 bytes — exactly the same as a raw pointer. Pointers from declaration to ownership, with every claim compiled and measured.
Advanced Concepts and Patterns in Encapsulation
While grasping the fundamentals of encapsulation is crucial, delving into advanced concepts and patterns elevates code design and maintainability further in C++. In this article, we will explore sophisticated aspects of encapsulation that go beyond the basics and provides you with a deeper understanding of its applications and impact on software development.
Functions in C Programming — Declaration, Types, Recursion & Function Pointers
Functions are the building blocks of every C program. This complete guide covers declaration, call by value vs reference, recursion, and function pointers — with tested examples.
Pointer to a Function is an address of a function in memory [C/C++]
This is a C program of showing how to use a pointer to a function. The pointer to a function
C Program to play with variables and their addresses
This is a simple C program to show pointers and how you can use pointers to print address of variables and their contents. This program prints the address of a variable, value of a variable, values of pointers.
