There are two default build configurations for each project type: Debug and Release. These configurations define how to build the project for the different situations.
To build the project and run it:
Notice in the Standard toolbar at the top of the IDE, that Debug shows as the active configuration.
The Build option builds only those files that have changed since they were last built, whereas the Rebuild option builds all the files in the project, regardless of whether they have changed since they were last built.
A console window opens, showing this character-based application running.
"5" is the code that tells this application to finish and the console closes.
