COMP6771 Advanced C++ Programming Week 2.3 STL Algorithms 1 STL: Algorithms STL Algorithms are functions that execute an algorithm on an abstract notion of an iterator. In this way, they can work on a number of containers as long as those containers can be represented via a relevant iterator. 2 Simple Example What’s the best […]

COMP6771 Advanced C++ Programming Week 5.1 Resource Management 1 Why? In this lecture While we have ignored heap resources (malloc/free) to date, they are a critical part of many libraries and we need to understand best practices around usage. What? new/delete copy and move semantics destructors lvalues and rvalues 2 Revision: Objects What is an
