C++ Type Casting: C-style vs C++ style

🚀 Day 46 of #100DaysOfCode 📌 LeetCode 844 — Backspace String Compare Today I tackled a problem that looks simple but exposes whether you can simulate string editing efficiently. 🧠 My Intuition Instead of building and modifying strings directly (which is messy and inefficient), I treated the input like a real typing scenario: Use a stack to simulate typing. Push normal characters. Pop when a # appears (acting as backspace). Build the final strings for both inputs and compare them. This makes the whole process clean and avoids unnecessary edge-case headaches. 🔥 Takeaway: When dealing with “string editors,” stacks simplify life. You avoid messy manual string manipulation and let the stack handle the backtracking for you. #leetcode #dsa #javacoding #codingjourney #100daysofcode #leetcode844 #programming

🚀 String Substrings in C++ Extracting substrings from a C++ string is done using the `substr()` method. This method takes two arguments: the starting position of the substring and the length of the substring. If the length is not specified, the substring extends to the end of the string. It's important to ensure that the starting position and length are within the bounds of the string to avoid errors. `substr()` creates a new string object containing the extracted substring. #c++ #programming #coding #tech #learning #professional #career #development

Recently, I came across an interesting feature introduced in 𝗖# 𝟴.𝟬 — the ability to 𝗽𝗿𝗼𝘃𝗶𝗱𝗲 𝗱𝗲𝗳𝗮𝘂𝗹𝘁 𝗺𝗲𝘁𝗵𝗼𝗱 𝗶𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻𝘀 inside interfaces. Traditionally, interfaces in C# could only 𝗱𝗲𝗳𝗶𝗻𝗲 𝗺𝗲𝘁𝗵𝗼𝗱 𝘀𝗶𝗴𝗻𝗮𝘁𝘂𝗿𝗲𝘀, and every class had to provide its own implementation.  Now, we can define 𝗱𝗲𝗳𝗮𝘂𝗹𝘁 𝗯𝗲𝗵𝗮𝘃𝗶𝗼𝗿 𝗱𝗶𝗿𝗲𝗰𝘁𝗹𝘆 𝗶𝗻𝘀𝗶𝗱𝗲 𝘁𝗵𝗲 𝗶𝗻𝘁𝗲𝗿𝗳𝗮𝗰𝗲, making it easier to evolve codebases without breaking existing implementations. If a class doesn’t override the method, it simply uses the default implementation.  If it does override, the class’s version takes precedence. #CSharp #DotNet #SoftwareDevelopment #Learning #Programming #CodeTips

What exactly is inside a C++ object? This doc explains the object model and its memory layout. ➜Objects hold only data members directly. ➜A hidden vptr is added for classes with virtual functions. ➜Multiple and virtual inheritance add extra pointers for base class management. ➜The vtable is global and not stored within each object. Understanding this helps write more efficient C++ code. #cpp #cplusplus #memorylayout #programming #coding #softwaredevelopment

🚀 Pointers to Structures and Classes in C++ Pointers can point to structures and classes in C++. The arrow operator (->) is used to access members of a structure or class through a pointer. This is a common technique for working with objects dynamically allocated on the heap. Pointers to objects allow for polymorphism and dynamic binding, fundamental concepts in object-oriented programming in C++. #c++ #programming #coding #tech #learning #professional #career #development

🔥 LeetCode POTD: Number of Substrings With Only 1s Today’s question was actually on the easier side… once you notice the key detail: it’s a binary string 👀. Here’s how my thought process went ⬇️ At first, I considered generating all substrings and then checking which ones contain only 1s. But of course… generating + checking = ❌ higher time complexity, which breaks the constraints. Not ideal. Then I took a step back and realized: 👉 Since it's a binary string, the substrings made of only 1s form clear continuous blocks. 👉 For each block of consecutive 1s of length k, the number of valid substrings is: k × (k + 1) / 2 ✨ Using this pattern, the whole problem can be solved in O(n) time. Dropped my solution in the image below 📸 Would love to hear how you approached it! 😄💬 #leetcode #leetcodechallenge #dsa #coding #programming #problemsolving #binarystrings

Did you know that C# has a special data type called a struct? Structures are an efficient way to represent small, immutable data, such as coordinates, colors, or dimensions. They store values directly in memory (stack), which makes them lighter and faster in many scenarios. Ideal for representing something simple, but with complete meaning. #CSharp #Programming #SoftwareDevelopment #Struct #DotNet #CSharpLanguage #CSharpLearning
