in this simple code, it replies error messages like this in replit ide.
/nix/store/039g378vc3pc3dvi9dzdlrd0i4q93qwf-binutils-2.39/bin/ld: /tmp/ex-805695.o: in function main': /home/runner/Programming-Methodologies/./Lab #5/ex.cpp:9: multiple definition of main’; /tmp/lab_exercise-c043ba.o:/home/runner/Programming-Methodologies/./lab_exercise.cpp:12: first defined here
clang-12: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [Makefile:10: main] Error 1
However, there are no errors in this code, and it works perfectly well in other ide.
What would be the problem, and are there any settings to fix this problem?
