C++ Function Overloading: How Name Mangling Resolves Ambiguity

One thing I always found slightly messy in C# was handling methods that return different types. Most of the time it meant: using object and adding extra checks or forcing everything into inheritance Neither felt great. Just saw that C# 15 is introducing Union Types, and it actually solves this in a clean way. Now you can define exactly what types are allowed, and the compiler makes sure you handle all of them. Feels like a small feature, but it’s going to make code a lot more readable and safer. #CSharp #DotNet #Developers #Programming

Invert Binary tree Approach: check if node is null or not if null return null swap left node and right ( not value complete node ) go to left (recursively) go to right (recursively) return node TC: O(N) SC:O(N)- recursive stack #DSA #programming #coding #problemSolving

Solved a Gray Code problem in C++ today. The task was to generate bit patterns from 0 to 2^n - 1 such that every consecutive pattern differs by only one bit, while always starting from 0. I used the Gray code formula: gray = i ^ (i >> 1) This makes the solution clean and efficient, and guarantees that adjacent codes differ by exactly one bit. Example for n = 2: 00 -> 01 -> 11 -> 10 What I like about this problem is how a simple bit manipulation formula can solve what looks like a complex sequence-generation challenge.

Most C++ developers learn noexcept as a compiler optimization hint. That framing is technically correct and completely useless for building intuition. Here is how I think about it now: Without noexcept: "Something might go wrong inside here that I am pushing up to you to handle." With noexcept: "I own my failure modes. I will never surprise you with an exception. Check my return value." It is a contract. Not a hint. This maps directly to how C developers already think, functions return error codes, callers check them. noexcept is C++ making that contract explicit and machine-enforced. Once I started reading it as intent rather than mechanism, I started putting it in far more places. And my APIs got cleaner because of it. If your function handles its own errors and signals failure through return values, mark it noexcept. You are telling the reader something important. #cpp #softwaredevelopment #programming

Solved the Target Sum Expression problem in C++ today. The challenge was to count how many different expressions can be formed by placing '+' or '-' before each number in an array so that the final result equals the target. For example: arr = [1, 1, 1, 1, 1], target = 3 Output = 5 What I learned: 1. Each number gives us two choices: add or subtract 2. This problem can be solved efficiently using Dynamic Programming 3. We track how many ways each sum can be formed as we move through the array Key takeaway: Instead of generating all expressions manually, DP helps us store intermediate results and avoid repeated work. #cpp #programming #dsa #dynamicprogramming #codingchallenge #leetcode #geekforgeeks #softwaredeveloper

🚀 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

🚀 Constructors and Destructors: Object Initialization and Cleanup (C++) Constructors are special member functions in C++ that are automatically called when an object is created. They are used to initialize the object's data members and ensure that the object is in a valid state. Destructors are also special member functions that are automatically called when an object is destroyed. They are used to release any resources held by the object, such as dynamically allocated memory, preventing memory leaks. Constructors and destructors are crucial for proper object lifecycle management. #c++ #programming #coding #tech #learning #professional #career #development

Subtree of another tree Approach: If subRoot is null - return true If root is null - return false If values match - check isIdentical(root, subRoot) If identical - return true Else - check left and right: isSubtree(root.left, subRoot) isSubtree(root.right, subRoot) Return true if found anywhere, otherwise false TC: O(N*M) -- n =no. of nodes in root, m = no. nodes in subRoot (worst case) SC: O(h) -- height of tree ( O(N) -- skewed tree || O(logN) -- balanced tree) #coding #programming #DSA #Consistency #Leetcode #CodingJourney
