This is the second type of comment supported by C#. A single-line comment begins with 

a

 and ends at the end of the line. Although styles vary, it is not uncommon for programmers 

to use multiline comments for longer remarks and single-line comments for brief, line-by-

line descriptions. (The third type of comment supported by C# aids in the creation of 

documentation and is described in Appendix A.)

The next line of code is shown here:

static void Main() {

This line begins the 

Main( )

 method. As mentioned earlier, in C#, a subroutine is called a 

method. As the comment preceding it suggests, this is the line at which the program will 

begin executing. All C# applications begin execution by calling 

Main( )

. The complete 

meaning of each part of this line cannot be given now, since it involves a detailed 

understanding of several other C# features. However, since many of the examples in 

this book will use this line of code, we will take a brief look at it here.

The line begins with the keyword
