I receive 2 errors, neither of which tell me which line the error occurred:
Since i am unsure of where or why these errors occur, my program is:Code:Error 2 fatal error LNK1120: 1 unresolved externals
Error 1 error LNK2019: unresolved external symbol _output referenced in function _main blah.obj
What can i do to get rid of these errors?Code:#include <stdio.h>
