Learn basic programming concepts of C# such as conditional statements, loop statements, and methods.

This highly interactive module begins with a simple “Hello, World!” program and proceeds 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 teaches us about exception handling 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
