C++ Level 2 – An Odyssey of C++: Standard Library

Overview:

This two days C++ elementary continuation course dives into the powerful features of the C++ Standard Library. Explore string abstractions, including regular expressions, and master I/O streams for efficient data handling. Get a complete overview of container types, algorithms with iterators and ranges, and modern memory management using smart pointers. Enhance your C++ skills by learning to reuse the rich APIs of the C++ Standard Library!

Goal/Benefits:

The major objective of this course is to get an overview of what the standard library of “Modern C++” – aka C++11, C++14, C++17, C++20, and the latest released C++23 – offers, so that “no new wheels have to be invented.

♦ String management

♦ Basic input/output - Making the user-defined type readable and writeable by understanding the concepts of the iostream-API

♦ Comprehend the different kinds of sequential and associative container classes

♦ Understand concept of iterators wiring the collections with the algorithms

♦ Understand concept of predicate function for controlling the behavior of an algorithm

♦ Understand the importance of sound memory management by always using smart pointers when applicable

♦ A set of exercises practicing the concepts

♦ Applying a unit testing as a natural way of testing/evaluating/running most of the exercises – in line with the predecessor course “C++ Level 1”

Audience/Participants:

This training is aimed programmers with some working experience of C++.

Previous Knowledge:

Since this class is the continuation of course “C++ Level 1 - An Odyssey of C++: Core Language”, a basic knowledge of C++ is required.

Practical Exercises:

During the training you will practice the presented concepts in a few exercises. We will use the open and free integrated development environment from Eclipse.
