🔍 C++ Variable Scope Variable scope defines where a variable can be accessed or used in a C++ program.Understanding scope is essential to avoid errors and write clean, predictable code. 🔹 1. Types of...

🔁 C++ Function Overloading Function overloading in C++ allows you to define multiple functions with the same name but with different parameter lists.The compiler decides which function to call based on the number, type,...

🔧 C++ Function Examples Below are clear and practical C++ function examples, from basic to advanced, to help you understand how functions are used in real programs. 1. Simple Function (No Parameters, No Return)...

📦 C++ Pass Array to a Function In C++, arrays are passed to functions by reference by default.That means the function receives the address of the first element, so changes inside the function affect...

🔁 C++ Functions – Pass By Reference Pass by reference allows a function to work on the original variable, not on a copy.Any change made inside the function directly affects the caller’s variable. 🔹...
