Inhalt: Design patterns solve the challenges software developers face over and over again. They are reusable, proven solutions that make your software more reliable and flexible to change. Creational design patterns move the creation of objects out of the main codebase and into separate classes-a best practice known as encapsulation. This course explores the five most popular creational design patterns for C++. To convince you of their merits, instructor Olivia Chiu first explains why we use design patterns in the first place, and what problems that creational patterns can help you solve. She then reviews the core concepts, implementation instructions, and examples for each pattern: Factory, Abstract Factory, Builder, Prototype, and Singleton. She also shows how to extend patterns and compare patterns to find the best fit for your applications. Umfang: 02:26:23.00
Inhalt: Successful programmers know more than just how to code. They also know how to think about solving problems. Code Clinic is a series of courses in which our instructors solve the same problems using different programming languages. In each course, instructors provide tips and tricks for working in a particular language and help you grasp why you might want to learn one language over another. Here, Olivia Stone works with C++. Throughout the course, Olivia provides an overview of her solutions to different challenges in C++. Challenges include topics such as geolocation, face recognition, and accessing peripherals. Visit other courses in the series to see how to solve the same challenges in languages like JavaScript, PHP, Python, Ruby, Go, and Swift. Umfang: 01:39:15.00
Inhalt: Love LEGOs? The next generation is ready to play. LEGO Mindstorms is a robotics kit designed for all experimenters-not just kids. Its advanced programming capabilities and robust hardware-sensors, motors, and intelligent EV3 brick-make LEGO Mindstorms a fun and challenging microcomputer system for programmers and tinkerers of any age. In this course, Olivia Chiu helps you "open the box" and build your first functional robot with LEGO Mindstorms. Learn how to unpack the hardware, connect to the programming interface, run prebuilt programs, and control the motors and sensors. Chapter 6, "Adding Flow to a Program," covers advanced programming topics such as transferring data between blocks, using variables to store temporary data, programming conditional logic, and looping actions to run again and again. By the end of the course, you'll have the skills to bring your own robotic creations to life. Umfang: 02:37:36.00
Inhalt: Want an easy way to query and update data? To query different data stores with a single tool? LINQ is the answer. Language-Integrated Query (LINQ) extends Visual Studio with powerful query capabilities based on C# and Visual Basic. LINQ makes big data doable. In LINQ with C# Essential Training, engineer Olivia Chiu introduces techniques for querying, updating, and transforming data with LINQ. She covers standard queries-such as finding overlaps in two datasets and creating hierarchies-as well as complex chained queries. She also shows how to group and join LINQ queries with lambda expressions, and use LINQ to query SQL databases and XML documents. Last but not least, Olivia provides tips for optimizing the performance of your queries. Umfang: 01:36:17.00
