3. Functions & Pass-by-Reference (&)

Overview: Avoid costly memory copies by passing arguments with `const Type&`.

Concept & Syntax Guide

Passing large objects by value makes full copies in memory. Using `const std::string& str` passes a direct reference without copying, maximizing execution speed.

Hands-On Practice Exercise

Write a Zero-Copy String Formatter

Write a function `void printTemplate(const std::string& name)` that prints "Template: " followed by the name.
