Gain insights into fundamental and advanced C# programming concepts. Learn about conditional statements, loops, methods, arrays, classes, inheritance, interfaces, and delegates through practical challenges.

This course introduces you to fundamental programming concepts in C#, one of the most popular languages in the world. The highly interactive course begins with a simple Hello world program and proceeds on to cover common concepts such as conditional statements, loop statements, and methods in C#. It also reflects upon the idea of arrays as well as the power they give to the programmer to write better code. Finally, it dives deeper in order to teach about advanced concepts such as classes, inheritance, interfaces, and delegates in C# through interactive challenges and exercises.

C# for Programmers: A Practical Guide

## Integer
An _integer_ is a number that does not have any decimal places. It is a whole number, for example, **1,2,3,4** are all integers. **4.3** is not. If you were to try and place the number **4.3** into an integer, the number would​ be truncated to **4**.

There are further different types in an integer as well. All of them differ in size which we'll discuss further down the lesson.

Let’s take a look at them one by one.
