It says Error main.cpp (4, 10) What does that Mean?

error main.cpp(4,10) means there is an error in the file main.cpp at line 4, column 10.

Is what you posted above the complete contents of main.cpp? Usually there is some boilerplate (#include statements, etc.) at the top of the file.

There is usually also some additional content in the “output” tab in VEXcode that gives you some information about what the error is, rather than just where it is in the file.
