Separate Files - the Details

1. Create a project with an appropriate name

2. The first file opened with be the one for the main - just make the appropriate changes and insert code

3. Add the remaining 2 files

    a. Select Project, Add New Item and select .cpp extension

        Insert the code for the implementation file 

    b. Select Project, Add New Item and select .h extension

        Insert the code for the header file

3. Run the program

    a. Open the file containing the main by selecting the appropriate tab at the top

    b. Run the program as before
