How do you transfer a program from ROBOTC to the virtual robot?

Transferring a program from ROBOTC to a virtual robot can be done using either of the first two methods listed. Pressing the "Download to Robot" button on the main menu effectively sends the compiled code directly to the virtual robot, initiating the program run. Similarly, selecting "Compile and Download" under the "Robot" menu serves the same purpose; it compiles the code and transfers it to the virtual robot for execution. Both actions accomplish the essential task of getting the program onto the virtual robot, making this option correct.

The other options do not achieve the desired outcome of transferring a program. Simply left-clicking on the virtual robot does not initiate any upload or download process, as it does not engage the program transfer functionality inherent in ROBOTC. Thus, using either of the first two methods is necessary to successfully interface with the virtual robot.
