no appropriate default constructor available :(

[arussell817]

Hello, I looked around and saw similar problems, but None of the answers seemed to help my situation. Im almost done with my HW Just have come across this minor bump.

The error is in the title, and is happening in my addressEntry header, or cpp. not sure: : error C2512: 'addressEntry' : no appropriate default constructor available

its confusing me because I cant find any reason it won't compile. any help would be appreciated.

Here is the Header and The cpp that are causing the problem.

#define ADDRESSENTRY_H

#include <string>

1. Use code tag properly:
[code=c++] source(s)

[/code]
It's too hard to answer you without line numbers in formatted (by code tag) source.

2. It's a very typical error. You define a constructor of the class addressEntry:

addressEntry::addressEntry(
    string phoneIn, 
    string birthIn,
    string emailIn,
    string pictIn);

Therefore you must explicitly define all constructors needed for this class using. You forgot this C++ rule ;)...

Look at this declaration from the main function:

addressEntry operatoraddressEntry;

Obviously, a default constructor needed (constructor without parameters). No such constructor in your class. Define it - that's all.

3. Try to avoid class name style like addressEntry. Common practice is AddressEntry (see Name and Address in your code).

[r.stiltskin]

The error message is telling you exactly what the problem is. In your main function you are declaring an addressEntry object addressEntry operatoraddressEntry; without supplying any arguments. In order to do that, your addressEntry class must have a default constructor, meaning a constructor that takes no arguments: addressEntry(); But the only constructor in your addressEntry class is this one addressEntry(string phoneIn, string birthIn, string emailIn, string pictIn); which takes 4 arguments.

Just add a default constructor to the class header and implementation files.

By the way, in your header file the "addressEntry::" part of each line is unnecessary. You only need that in the implementation file.

Look,
Here's the key:
If you do dont provide any constructor to the Class, the compiler generates, automatically, a defalt no-argument constructor.
But, if define even one constructor yourself, the compiler won't generate any constructor for you.
Saying this, I mean that if you defined a 2 argument constructor and no other constructor is defined, you cannot create object without specifying those two arguments. You have two options, either define a dummy no-argument constructor, or use the default arguments in your 2-argument constructor.
