Programming C# 6, Part 05 of 12: Adv Data Types and Operators

Course description

Data types and variables are a fundamental part of learning to program, and C# provides a robust set of language features to work with variables and data in memory. In this course, you’ll learn about many variable data types, as well as how to convert between them and how to handle null values. You’ll also learn about altering and evaluating data with operators, from simple mathematical functions like addition and subtraction to logical and other advanced operators.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course builds upon: Programming C# 6: Getting started, Your First App, Projects and Syntax and Variables and Data Types.
