C++ File Handling!

Hello, every one there, I am stuck on a problem..!! Actually, I tried to make a Telephone Dictionary and for this I use the following code, when I am inserting a contact it successfully do this. But when I want to delete a contact then I am not get the expected result.!!!
Suppose, in my contacts.bat file, the following contact list is written:

Anus Mehmood I-10 0567 1244
Khizar Iqbal I-14 0333 068
Zarar Haider I-8 0456 456
Uzair Iqbal I-15 1234 5678
Naqash Mehmood I-16 1234 5678

and I want to delete the contact having first name Khizar and second name Iqbal, then my program do this but after it gives me the following result..!!

Anus Mehmood I-10 0567 1244
Zarar Haider I-8 0456 456
Naqash Mehmood I-16 1234 5678
Naqash Mehmood I-16 1234 5678

i.e., Uzair Iqbal is also removed but Naqash Mehmood is written for the two times!!
and after this if I want to remove the Anus Mehmood contact, them Naqash Mehmood contact is also removed..!!!
As long as I know, the is an error in the following line:
if (strcmp (name1, first_name) != 0 && strcmp(name2, last_name) != 0)
ANY BODY CAN HELP ME, PLEASE...!!! HERE IS MY CODE..!!!
