L5 C++ Programming | Variables and Constants in C++ | Variable Naming Rules Explained in C++ | CWC

💻 Welcome to Carrier With Code (CWC) In this video, we will learn about Variables and Constants in C++ Programming. Variables are used to store data in memory, while constants store fixed values that cannot be changed during program execution. This topic is very important for beginners learning C++ programming. 🧩 What You’ll Learn ✔️ What is Variable in C++ ✔️ What is Constant in C++ ✔️ Rules for Variable Naming ✔️ Examples of Variables ✔️ Memory concept 🧠 What is Variable? A variable is a named memory location used to store data. 👉 Example: int age = 20; Here: int → data type age → variable name 20 → value 🧠 What is Constant? A constant is a value that cannot be changed during program execution. 👉 Example: const float PI = 3.14; 📜 Rules for Variable Naming in C++ ✔️ Variable name can contain: Letters (A-Z, a-z) Digits (0-9) Underscore (_) ❌ Cannot start with a number ❌ No spaces allowed ❌ Special symbols not allowed ❌ Keywords cannot be used 🧠 Concepts Covered ✔️ Variables in C++ ✔️ Constants in C++ ✔️ Naming rules ✔️ Memory basics 🔑 SEO Keywords variables in c++ constants in c++ variable naming rules in c++ what is variable in c++ c++ programming basics learn c++ programming c++ tutorial for beginners carrier with code 📚 Hashtags #CPPProgramming #VariablesInCPP #ConstantsInCPP #LearnCPP #CPlusPlus #CodingForBeginners #CarrierWithCode
