Code ./main doesn’t exist C++

I’m not sure why my code is having an error, I updated the .replit file so that my code would run driver.cpp and not main and it still won’t run

Try renaming Driver.cpp to main.cpp.

I tried that and then I had to change my makefile so that it would read main.cpp and create main.o for sorting. after I did that the same error occurred where main doesnt exist.
