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

## Introduction
Catching the problem is a good idea, but it can sometimes leave your program in an invalid state. 

For example, if you open a connection to a database, an error occurs and you throw an exception. Where would you close the connection? In both the try AND catch blocks? Well, problems may occur before the close is carried out.

Therefore, the **finally statement allows you to cater for the "in all cases do this" circumstance.**

### Example
See the example below:
