file handling

myme (2)
my program is a telephone directory, it is a list of content details includes persons name and his/her telephone number. My program should be able to add, edit, display and search a contact.

so here is my concern and i hope i got some help thank you in advance. I've already done the codes but there is a little problem. when the user add an new file it's working, she/he can put his/her name and telephone number but when he/she want to see or display the data the output is kinnda messy he/she can see the information but the telephone number appears in a special characters like hearts,smiles,mathematical sign, and also the search one when the user search a name the one she/he's been searching have already a name and a telephone number but when the output is not correct the name is exact but the telephone number is not correct.

here is my codes for the searching and editing.

Hi myme,

I wouldn't go with type integer for telephone numbers. You'll be better off using strings or char arrays for that. Reason: int has a small valid range, can't handle extra chars linke 0101-456778 or /+ etc...
