Your First Visual Studio 2019 Program

• After installing Visual Studio according to previous instructions, go ahead and launch it.
• Click on "Create New Project". There are many choices. For now, we will be making an empty Console App that prints "Hello World."
• Type "console C++" into the text box above to filter the number of project choices, then choose "Empty Project" and click "Next."
• Choose a "Location" and "Project name" that you like, or leave them at their defaults. Also check "Place solution and project in the same directory." Then click "Create."
• At this point, you should see the "Solution Explorer" window. If you don't, click the "View" menu item and then you can bring up the Solution Explorer.
• Visual Studio created two layers for you, a Solution and a Project within that solution, both with the name you provided in the last step. Software companies that have several products that share code might take advantage of multiple projects within a solution. For us, it is overkill.
• Our project starts empty. To add a C++ source file to it, click the "Project" menu item, then "Add New Item." Next, you may have to navigate on the left until you find "Visual C++" for the language. Then choose "C++ File" on the right. "Name" it at the bottom, and click "Add." (Do NOT change the "Location.")
• Now in the Solution Explorer you should see that you have your new C++ file listed under "Source Files." It should also be opened up so you can add C++ code to that file. If it ever gets closed, you can reopen it by double clicking on its name in the Solution Explorer.
• Now enter some C++ code such as the following:
  

  #include <iostream>
  int main()
  {
  	std::cout << "Hello World";
  	return 0;
  }
  	

• To compile it, click on the "Build" menu item, "Build Solution" subitem. All .cpp files in your project will be compiled into object code and the results will be linked into one executable file with the same name as your project name.
• To execute your code, click on the "Debug" menu item, "Start Debugging" subitem, or use the hot key F5. Visual Studio should open a console window, print "Hellow World," and wait for you to press a key before closing that window and returning you to the Visual Studio environment.
• Remember from the beginning which "Location" you chose for your project. If you forgot, you can find out by doing a "File," "Save As" on one of your .cpp files. Don't actually save it, just note the directory Location. After you quit Visual Studio, you can go to that same directory Location and click on the .sln file to restart your solution/project and continue working.
