Preventing Memory Leaks in C++ Inheritance with Virtual Destructors

🚀 Dangling Pointers and Memory Leaks in C++ Dangling pointers occur when a pointer points to a memory location that has already been deallocated. Dereferencing a dangling pointer leads to undefined behavior. Memory leaks occur when dynamically allocated memory is not properly deallocated using `delete`. Both dangling pointers and memory leaks are common sources of errors in C++ programs. Smart pointers (like `unique_ptr` and `shared_ptr`) help prevent these issues by automating memory management. #c++ #programming #coding #tech #learning #professional #career #development

🚀 String Erasure in C++ The `erase()` method of the `std::string` class is used to remove characters from a string. It takes a starting position and a length as arguments. If the length is omitted, all characters from the starting position to the end of the string are removed. Erasing characters modifies the original string object. Careful consideration of the starting position and length is crucial to avoid unintended consequences. #c++ #programming #coding #tech #learning #professional #career #development

🚀 Abstraction using Access Modifiers in C++ (Oop Concepts) C++ utilizes access modifiers (public, private, protected) to control the visibility of class members, enabling abstraction. Private members are only accessible within the class itself, hiding implementation details. Public members define the interface of the class, providing access to essential functionalities. Protected members are accessible within the class and its derived classes, supporting inheritance-based abstraction. This allows for fine-grained control over what is exposed and what is hidden. #oopconcepts #programming #coding #tech #learning #professional #career #development

🚀 Using `unique_ptr` for Exclusive Ownership in C++ `unique_ptr` represents exclusive ownership of a dynamically allocated object. Only one `unique_ptr` can point to a given object at a time. When the `unique_ptr` goes out of scope, the object it manages is automatically deleted. This ensures that the object's lifetime is tied to the `unique_ptr`, preventing memory leaks. `unique_ptr` is generally preferred over raw pointers when exclusive ownership is desired. #c++ #programming #coding #tech #learning #professional #career #development

Ever needed to parse a binary file format or call a native API that expects raw bytes? What did you reach for: MemoryBlock, Ptr, or something else? #LowLevel #Programming

The code solves a problem finding maximum subarray sum in an array. What i have done here solve the problem properly. But here the new problem is the code is not optimized. It becomes huge when the input is big. Here, Time Complexity = O(n²) Space Complexity = O(1)/constant It gets time limit exceeded when the input is big. So when we run this code on a server, it demand a huge CPU power and increases cost and decreases efficiency. This shows the need of optimal solution. That's we need to learn how to write code optimally. There's an algorithm that solves this problem optimally. Can you guess that? If you can, comment below. This problem is from Leetcode-53. #programming #leetcode #coding

🚀 C++ Basic Syntax: Statements and Semicolons In C++, a statement is a complete instruction that the computer executes. Every statement in C++ must end with a semicolon (;). The semicolon tells the compiler where a statement ends. Forgetting the semicolon will result in a compilation error. This is a fundamental aspect of C++ syntax, ensuring the compiler can correctly parse and execute your code. #c++ #programming #coding #tech #learning #professional #career #development

Programming looks simple—but behind every line of code, powerful hardware is at work. 💻 Understanding components like CPU, RAM, and storage helps you see what really happens in the backend. Programming languages make it easier, but true mastery comes from knowing how things run underneath. With 2026 bringing advanced tech like AI and faster computing, this knowledge will set you apart. #Programming #SoftwareDevelopment  #TechFundamentals #BackendDevelopment #FutureOfTech

Continuing my C Programming series! In my last post, I covered the 32 keywords of C and how they form the foundation of the language. This time, I’m focusing on the structure of a C program—what a typical C file looks like and how everything fits together, from header files to the main() function, compilation, and execution. If you’re learning C, understanding this flow is an important next step before writing bigger programs. This is part of my ongoing series on Advanced C Programming as part of my Embedded Systems course at Emertxe Information Technologies. #CProgramming #ProgrammingBasics #EmbeddedSystems #Emertxe #TechLearning

Writing fast, reliable software sometimes means solving problems that have no obvious answer. Our R&D team just published a #TechTalk article documenting one of those problems: how do you make #Cython classes that are created automatically at runtime carry the right data with them, without slowing things down? The article walks through every approach they tried, why some fell short, and the solution they landed on. It also covers a subtle crash bug hiding in the final design, and how to handle it safely. 🔗 Read it here: https://lnkd.in/en4mP4cM #SoftwareEngineering #Programming
