Template Concepts

Generic Programming

Write code that works with multiple data types without repetition

Template Instantiation

Compiler generates specific functions for each type you use

Type Deduction

Compiler automatically determines template parameter types

Template Tips & Best Practices
🎯 Start Simple

Begin with single-parameter templates like max() or swap() before moving to complex ones.

🔧 Use Type Constraints

Templates work with any type that supports the operations you use. Be mindful of requirements.

⚡ Compilation Time

Templates are compiled for each type used. More instantiations = longer compile times.

🚀 STL Connection

Understanding templates is key to using STL containers, algorithms, and iterators effectively.
