C# Data Types and Variables

在本课程中，我们研究如何使用C＃程序中的变量存储不同类型的数据。C＃是一种强类型的语言，这意味着当您在代码中操作数据时，必须将数据保留在专门设计用于保存此类数据的变量中。例如，文本以字符串数据类型存储，而字母以char形式存储。有十多种不同的数字数据类型，它们可以忠实地代表其大小，准确性或精度。我们研究了在计算机二进制环境中处理小数的一些怪癖。每个主题都有深入的代码示例，以说明所讨论的概念并使您更全面地熟悉C＃编程。

本课程以C＃简介课程中涵盖的关键概念和示例为基础。它包括指导性的演示，可为您提供有关如何处理所涉及概念的实践知识。

Description
In this course, we look at how different types of data are stored using variables within a C# program. C# is a strongly typed language, meaning when you manipulate data in code, you must keep the data in variables that are specifically designed to hold that kind of data. For example, text is stored in a string data type and a letter in a char. There are over ten different numeric data types that vary in size and accuracy or precision of the data they can faithfully represent. We investigate some of the quirks in dealing with fractional numbers in a computer’s binary environment. There are in-depth code examples for each of these topics to illustrate the discussed concepts and make you more familiar with C# programming in general.

This course builds upon the key concepts and examples covered in the Introduction to C# course. It includes guided demonstrations to give you practical knowledge of how to handle the concepts covered.

Learning Objectives
Understand what variables are and how they’re stored
Learn about data types for storing and manipulating text values
Learn about the various data types for storing and manipulating whole and fractional numbers
Learn about variables for storing multiple values of the same data type

Intended Audience
This course is intended for anyone who has a basic understanding of C# and now wants to build upon that knowledge.

Prerequisites
This course carries on from our Introduction to C# course, so we suggest taking that one first if you haven’t already done so.
