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

The <code>Console</code> is a class in the <code>System</code>

We use the “.”, dot, operator to separate subordinate program elements

We use the “.”, dot, operator to separate subordinate program elements

The line `Console.WriteLine("Welcome to C# course")` should not have a semi colon at the end

The function `main()` should be written as `Main()` instead

The `class Course` should have a semicolon following the last closing bracket

`Console.Readline()` should be used instead of `Console.WriteLine()`

What is the error in the code below?
```
using System;

class Course
{
    static void main()
    {
      Console.WriteLine("Welcome to C# course"); 
    }
}
```

What is the error in the code below?
<pre><code>using System;

class Course
{
 static void main()
 {
 Console.WriteLine(&quot;Welcome to C# course&quot;); 
 }
}
</code></pre>

The Main method cannot be declared with a parameter and hence cannot return an integer value

The WriteLine method takes a string and a variable number of additional arguments
