error in C++: out-of-line definition - c++

Question

CustomerInfo.cpp
#include "CustomerInfo.h" // <==== Funtion Definition
CustomerInfo::CustomerInfo() // <==== The Scope Resolution which is two colons :: gives me access to the class
{
newZipCode = 0;
}
CustomerInfo::CustomerInfo(string name, string address, int zipCode)
{
newName = name;
newAddress = address;
newZipCode = zipCode;
}
CustomerInfo::~CustomerInfo()
{
}
string CustomerInfo::getName() const
{
return newName;
}
string CustomerInfo::getAddress() const
{
return newAddress;
}
int CustomerInfo::getZipCode() const
{
return newZipCode;
}
The main.cpp file
#include <iostream>
#include <string>
#include "CustomerInfo.h"
using namespace std;
int main()
{
string name;
string address;
int zipCode;
cout << "Enter your name: ";
getline (cin, name);
cout << "Enter your address" << endl;
getline (cin, address);
cout << "Enter your ZipCode: ";
cin >> zipCode;
CustomerInfo Real_1(name, address, zipCode);
cout << endl << " Name: " << Real_1.getName() << endl <<
"Address: " << Real_1.getAddress() << endl <<
"ZipCode: " << Real_1.getZipCode() << endl;
return 0;
}
The CustomerInfo.h file
#ifndef CUSTOMERINFO_H
#define CUSTOMERINFO_H
// Header ==> Function Declaration
#include <iostream>
#include <string>
using namespace std;
class CustomerInfo
{
public:
CustomerInfo(); // <==== Default Constructor
CustomerInfo(string, int); // <==== Overload Constructor
~CustomerInfo(); // <===== Destructor - Done using an object it will be destroyed out of memory'
string getName() const; // <==== Accessor Functions - Return member variables one value at a time. In addition, no void function will be used.
// getName - returns name of person
string getAddress() const;
// getAddress - returns address of person
int getZipCode() const;
// getZipCode - returns zipcode of person
private:
//Member Variables
string newName;
string newAddress;
int newZipCode;
}; // <=== Requires semicolon after brackets for classes
#endif // CUSTOMERINFO_H
The error I receive is out-of-line definition of 'CustomerInfo' does not match any declaration in 'CustomerInfo'
The following line is the error
CustomerInfo::CustomerInfo(string name, string address, int zipCode)

Answer 1

Your problem seems to be that you define a constructor
CustomerInfo::CustomerInfo(string name, string address, int zipCode)
which does not appear in the class definition (in CustomerInfo.h). The closest one is
CustomerInfo(string, int);
but it doesn't match the signature. Just replace it with
CustomerInfo(string name, string address, int zipCode);
to your class definition in the header file.
