Answer 1

Assuming you dropped several .cpp files in the same project (containing a main in each), you can :

• Right-click on your .cpp file and Properties > C/C++ build > Settings > Manage Configurations.
• Create a new configuration and set it as the active one + OK.
• Select the newly created configuration.
• Select the files you don't want to run for this configuration, open Properties and check "exclude resource form build", for each one.
• Select the file(s) you want to keep for that configuration and make sure "exclude resource form build" is unchecked.
• Build the Project
• Press button play

Finally, to switch from one run configuration to another, go to Project > Properties > Manage Configurations and change the active one. Rebuild and run.

EDIT: as shivi mentioned, the most painful part (excluding resources form build) can be done in one single shot by multi-selecting the files to exclude in the Package Explorer view and Right-click > Resource Configurations > Exclude from build....

That's the best we can do...
