Writing a C# Program

Writing a program in C# involves writing the Main() method. Before w riting a program, you need to select the template from the available templates for C#. C# provides you with a variety of templates, as shown in Figure 3-2.

The execution of a C# program starts with the execution of the Main() method. Therefore, you need to write the Main() method for each program in C#. The Main() method is of the type static and returns a value of the type void or int.

If the Main() method is of the type void, it does not return a value. However, a Main() method of the type integer returns an integer type variable. The following is the syntax of a Main() method.

<modifier> static <data type> Main ()

Here, modifier is the access modifier of the Main() method and the data type is

void or integer.
