Error help

[Griffinflame21]

Hello! I am still fairly new to C++ and need a bit of help or guidance.
Here is my 3 files of code: Record.h, Record.cpp, and main.cpp;
Record.h

  #include <cstdlib>
#include <iostream>
#include <string>
using namespace std;

#ifndef RECORD_H
#define RECORD_H

class Record
{
private:
    string recNum;
    string firstName;
    string lastName;
    string age;
    string phoneNum;
public:
    void setRecNum(string recIn);
    void setFirstName(string nameIn);
    void setLastName(string nameIn);
    void setAge(string ageIn);
    void setTelephone(string phoneIn);
    string getRecNum();
    string getFirstName();
    string getLastName();
    string getAge();
    string getTelephone();
};

#endif /* RECORD_H */ 

Record.cpp

  #include "Record.h"
#include <string>
using namespace std;

void Record::setRecNum(string recIn)
{
    recNum = recIn;
}

void Record::setFirstName(string nameIn)
{
    firstName = nameIn;
}

void Record::setLastName(string nameIn)
{
    lastName = nameIn;
}

void Record::setAge(string ageIn)
{
    age = ageIn;
}

void Record::setTelephone(string phoneIn)
{
    phoneNum = phoneIn;
}

string Record::getRecNum()
{
return recNum;
}

string Record::getFirstName()
{
return firstName;
}

string Record::getLastName()
{
return lastName;
}

string Record::getAge()
{
return age;
}

string Record::getTelephone()
{
return phoneNum;
}

main.cpp

#include <cstdlib>
#include <iostream>
#include <string>
#include "Record.h"
using namespace std;

int main() 
{
    int i = 0;
    Record book[i];
    for(i = 0; i<10; i++)
    {
        cout << "Record number: ";
        cin >> book[i].setRecNum();
        cout << "First name: ";
        cin >> book[i].setFirstName();
        cout << "Last name: ";
        cin >> book[i].setLastName();
        cout << "Age: ";
        cin >> book[i].setAge();
        cout << "Telephone number: ";
        cin >> book[i].setTelephone();
    }
    
    for(i=0; i<10; i++)
    {
        cout<<book[i].getRecNum();
        cout<<book[i].getFirstName();
        cout<<book[i].getLastName();
        cout<<book[i].getAge();
        cout<<book[i].getTelephone();
    }
    return 0;
}

The problem I am getting is in main.cpp. Error: no matching function for call to 'Record::setRecNum()' Same for all of the other lines dealing with input.

[jonnin]

it takes a string but you call it with nothing.

book[i].setRecNum();

setRecNum(string recIn);

you need something like

book[i].setRecNum(somestringvariable);

[ar2007]

Because your members function having 1 argument.
Example: change line 14 with

string x = "" ;
cin >>  x ;
book[ i ].setRecNum( x ) ;

[Griffinflame21]

How would I do that so that a user can input the string variable that goes in the parenthesis of book[I].setRecNum(stringvariablehere);?

Posted on delay. :)

@ar2007, I tried replacing every cin with what you suggested(but different variables for each such as Record number variable was string r, first name variable was string f, etc. Now my program runs, but once I type in the Record number(the first time) it says run failed. But gives me no error messages.

int i = 0;
    Record book[i];
    for(i = 0; i<10; i++)
    {
        cout << "Record number: ";
        string r = "";
        cin >> r;
        book[i].setRecNum(r);
        cout << "First name: ";
        string f = "";
        cin >> f;
        book[i].setFirstName(f);
        cout << "Last name: ";
        string l = "";
        cin >> l;
        book[i].setLastName(l);
        cout << "Age: ";
        string a = "";
        cin >> a;
        book[i].setAge(a);
        cout << "Telephone number: ";
        string t = "";
        cin >> t;
        book[i].setTelephone(t);
    }

If I change Record book[I] to just Record book the program works fine. I don't understand why it isn't working when it is an array...

My full program is now:
Record.h

#include <cstdlib>
#include <iostream>

    {
    }
    
    Record(string recIn) :recNum(recIn)
    {
    }
    
    Record(string recIn, string fnameIn, string lnameIn, string ageIn, string phoneIn)
            :recNum(recIn), firstName(fnameIn), lastName(lnameIn), age(ageIn), phoneNum(phoneIn)
    {
    }
    //set functions
    void setRecNum(string recIn);
    void setFirstName(string nameIn);
    void setLastName(string nameIn);
    void setAge(string ageIn);
    void setTelephone(string phoneIn);
    //get functions
    string getRecNum();
    string getFirstName();
    string getLastName();

                InputInfo();
                break;
            case 2:
                Display();
                break;

                cin >> a;
                book[i].setAge(a);

                cout<<book[i].getLastName();
                cout<<"\n";
                cout<< "Age: ";
                cout<<book[i].getAge();
                cout<<"\n";
                cout<< "Telephone number: ";
                cout<<book[i].getTelephone();
                cout<<"\n";
            }
        Menu();
    };
    void Exit()
    {
        cout << "Closing...";
    };
} Recordsbook;

int main()
{
    Recordsbook.Menu();
}

The solution to my previous problem was SUPER simple. I changed Record book[I] to Record book[10].


Thank you all so much for the help! I wouldn't have come up with the solution without y'alls help!
