You must check for successful opening. If there is a failure fopen()
returns NULL.


So you should do:

fp1=fopen(archme, "r");

if(fp1==NULL)
{
fprintf(stderr, "Men the lifeboats. Women and children first!\n");
return EXIT_FAILURE;
}

etc.

No you do not need to fflush(). Simply you probably fclose(NULL); (see
above). Or some other mistake in code you did not mention.
