Advanced Template Programming in C++

Course objectives

After completing this course you will be able to:

• use generic programming techniques in C++
• use templates to write code that is fast, secure and reusable
• implement classic generic programming techniques: tag dispatching, SFINAE, CRTP
• use templates when designing classes: Policy Based Design
• implement modern templates using constraints and concepts

Course syllabus
