}
printf("\tRECORD DELETED!!\n");
system ("pause");
Records.close();
rectemp.close();
remove("Records.txt");
rename("rectemp.txt","Records.txt");
main_function(); }
}

btw:
with this:
1 2
|
if(Records.eof())
break;
|
what's the difference?
Thanks! I removed it and changed the file definitions to
1 2 3 4

ofstream rectemp ("rectemp.txt");
//ifstream Records ("Records.txt");
fstream Records;
Records.open("Records.txt", ios::in | ios::out);
