Hello,
I just started C++ and I have this assignment to write. I started writing it but I can't seem to get this one thing and that is how to create a new contact and store it in a file.
I need to know if I used the structure correctly. Also I don't know how you create multiple contacts with a loop. I wouldn't necessarily need the answer from you guys. I just want to know what topics I need to learn to be able to do this.
What do I need to use? That's all I need. I can write the programs for myself.

Also if you guys can tell me how you search for and display a single contact. That would be helpful. Thanks for understanding.

pscha3

Here's the code:

The use of ur structure seems fine...
To input multiple contacts just put an infinite while loop to enclose ur switch statment... so u will quit whenever u click quit.. that way u can get rid of the restart command..
For searching...
U should be storing ur contacts in an array of structures..now u r overwriting whenever the user says he wants to add a contact.. so just change that also.. so whenever u r supposed to search.. just ask for the field and find that entry that u require by a simple linear search...

Yea actually after an hour or so after my first post I totally knew how to do it. Read my book again. So yea. My only question is how do I get more memory for storing data. Since in my new program, here it is

When i create a new contact, it skips the first field which is Name. And it overwrites a lot of time. Like if I want to put in a phone number, If I put like more than three numbers it skips all the other fields and goes directly to the end.

ok for your first issue the Inabillity to Name your new contact after creating the file i added another "cin.getline(Name,40);"
to the code just before the action is requested by the programme now the stage being skiped is no one of no importance

void Create()
{
	cout<<""<<endl;
	cout<<"*This will let you create a new contact*"<<endl;
	cout<<"*Please provide the following information*"<<endl;
	cout<<"*When you want to skip a filed, just press enter*"<<endl;
	cout<<""<<endl;
	cout<<"Please enter a file name for the contact."<<endl;
	cout<<"We recommend using the person's name."<<endl;
	cin>>Filename;
	cout<<""<<endl;
	cout<<"Creating..."<<endl;
	cout<<""<<endl;
	
	//This is the place where the user enters the information.
	Data.open(Filename,ios::out);
       cin.getline(Name,40);
	cout<<"Name: "; 
	cin.getline(Name,40);
	cout<<""<<endl;

Also the other problem you had of telephone numbers crashing/reseting the programme if more that a few numbers are used ... I have no idea why that is happening but if you can afford to .. redefine the Telephone numbers as Char's
like this

char Home[12];
char Business[12];
char Cell[12];
char Other[12];

or as strings

stringHome;
stringBusiness;
stringCell;
stringOther;

or you could use plain simple strings it all depends and what you are goin to be doing with the data after if has been created

If they are still working on this more than 3.5 years later, there is something very wrong. ;)

I suppose it could still be of use to someone that comes across this searching for help with their own problem.
