c:/mingw/bin/../lib/gcc/mingw32/6.3.0/../../../../mingw32/bin/ld.exe: cannot open output file a.exe: Permission denied collect2.exe: error: ld returned 1 exit status
This is what it exactly says when I try to run a code. I tried opening task manager and end a.exe. But it just comes again and when I run the code , it shows the same error.
