C++ Standard Template Library in Practice

Pågående kurs – UDEMY 2021-07


C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. In particular, it is the Standard Template Library (STL) that gives C++ its power. In this course, we show you how.

Using real-world examples, we focus on how STL handles and manipulates data. We examine containers and iterators, and how data can be transformed into meaningful information using algorithms. There is coverage of I/O streams, strings and numerical methods, and how performance can be optimized through careful consideration of memory allocation and manipulation. We also demonstrate how multitasking and shared data is handled through concurrency and parallelism classes and utilities.

By the end of the course, you will understand the newer aspects of C++ STL and will be able to overcome tasks that are time-consuming or would break your stride while developing.

About the Author

James Slocum has been a professional developer for over 10 years. He graduated from NJIT with a Bachelor’s degree in Computer Engineering in 2008, and again with a Master’s in Computer Science in 2011. He currently works for Audible as a software engineer and tech lead for the library group. The languages he uses the most are Java, JavaScript, C++, and Dart. In his free time, he enjoys learning about new languages and technology.

What you’ll learn

  • Efficient and effective ways to store data using STL containers
  • Manage application performance using STL memory allocation classes, and enhance these classes by developing your allocation routines
  • How data is structured and how the structure can be traversed using iterators
  • How algorithms are used to transform data into useful and meaningful information
  • Multitasking and managing shared data using concurrency and parallelism
  • Managing input and output (I/O) using streams and the role of stream buffers
  • How the STL has standardized common tasks

Are there any course requirements or prerequisites?

  • This video course is designed for both experienced C++ programmers and people with some knowledge of OOP concepts.

About this course

Build Cross Platform C++ GUI Applications with Qt, Run them on Windows, Mac, Linux, Android, iOS and Embedded Devices

This course will take you from zero to a level where you can write any Qt C++ Gui application you may want. It is aimed at complete beginners but people with varying levels of experience wishing to learn Qt C++ Gui will equally find it useful.

Qt is second to none in the field of building cross platform GUI application based on C++. It can currently be used to build software that runs on virtually any platform out there: Windows, Mac, Linux, Android, IOS and even embedded systems. You basically build your software once and all you have to do is build it for your desired platform and voila !

The course starts with a complete beginner to both C++ and Qt in mind, and we take  you through the the process of getting your environment set up on your platform of choice :

  • We do a live install of Qt Creator on Windows
  • We do a live install of Qt Creator on Linux
  • We guide you though how you would install Qt Creator on a Mac
  • We guide you through Qt Creator showing you the tools that work together to get your application built

We then take you on a tour of the C++ programming language, covering the concepts deemed important to start working with Qt to build your shinny GUI applications. You don’t need to be a C++ wizard to start writing your applications using Qt. One of the goals behind Qt itself is to be as easy to use as possible, helping you to focus on your application logic rather than the C++ complex plumbing. This does not mean that you can do with zero C++ knowledge though. That’s why we take you on a tour to cover the basic concepts of the language covering topics like:

  • Running your first console application and understanding the main function
  • Streams that help you write and read data from your C++ applications
  • Variables and Data Types
  • Basic C++ Operators and Control flow where among other things you learn about if clauses and loops
  • Build an app to guess numbers and put together the concepts learned so far
  • C++ Functions
  • C++ classes
  • Building your first Qt C++ GUI Application
  • Building a GUI Version of your Number guessing game

We then visit the fascinating concept signals and slots in Qt where  you learn the most flexible way to respond to events : 

  • We’ll explore lambda functions in C++ in general, we’ll need them to use their SIGNAL SLOT syntax
  • We explore different ways to connect signals to slots in Qt
  • We then do a concept enforcing demo for you to try them out

Next we dive in the Qt Widgets section and visit some of the most important widget classes in Qt : 

  • QWiget
  • QMainWindow
  • QMessageBox
  • QPushButton
  • QLineEdit
  • QTextEdit
  • QLabel
  • QHBoxLayout, QVBoxLayout, QGridLayout
  • We visit size policies and stretches and how they help tie the knots in  your layouts
  • QCheckBox and QRadioButton
  • QList
  • QComboBox
  • QListWidget
  • QTabWidget
  • QMenu, QToolBar, QAction

Dialogs are explored next , we look at QDialog and how to build  your own custom dialog class from scratch , QDialogButtonBox, QMessageBox, QFontDialog, QFileDialog, QInputDialog and how they add a layer of interactivity to your Qt GUI applications.

We then go on and explore how to work with the Qt Resource System , Styling your Qt applications with QStyle, QPalette and Style Sheets, Saving your application settings with QSetting, Working with Files and Directories using QFile and QDir and we wrap up the course with a tour of the network capabilities of Qt where we : 

  • See the different classes that are available to work with networks in Qt
  • Build an application to download web pages in our Qt Applications
  • Build an application to consume Rest APIs in your Qt Applications

This course was designed to help you succeed in becoming a Qt Gui application developer regardless of your current level of expertise. The only requirement is to bring in an open mind and a strong willingness to learn. Now, please check out some of the preview videos andl let’s get you STARTED building cross platform GUI applications using Qt.

What you’ll learn

  • The fundamentals of working with Qt to build C++ Gui Applications
  • Working with Qt Widget Classes
  • Working with Dialog Classes
  • Using the Qt Resource System
  • Styling Qt Applications
  • Working with Networks to fetch HTTP Data
  • Working with the File System
  • Model View Architecture
