Thread: Problem getting data stored in header file via a function...

Hello folks,

I am working on an assignment for school and I would greatly appreciate some help with my code. I would like to retrieve some data from my header via a function in my main. However, when I call the function in my main the text shows up, but not the data. If I attempt to retrieve the data straight in the main without the use of a function, I get the right results, it is when I use a function that I have the problem.

Some help would be greatly appreciate it.

here is my header:

Code:

#ifndef HEADER_H
#define HEADER_H

#include <iostream>
#include <string>
#include <cstring>

using namespace std;

class Account
{
    public:


    char first_name[20];
    char last_name[20];
    float sin_number;
    char account_type[10];
    int number_of_transactions;


void set_data(char fname[20],char lname[20],float sinnum, int acctype, int numtrans)
{
    strcpy (first_name,fname);
    strcpy (last_name,lname);
    sin_number = sinnum;
    if (acctype = 1)
    {
        strcpy(account_type, "Chequing");
    }
    if (acctype = 2)
    {
        strcpy(account_type,"Savings");
    }
    number_of_transactions = numtrans;
}

void get_data()
{
    cout<<"the first name is : "<<first_name<<endl;
    cout<<"the last name is : "<<last_name<<endl;
    cout<<"the sin number is : "<<sin_number<<endl;
    cout<<"the account type is : "<<account_type<<endl;
    cout<<"the number of transactions is : "<<number_of_transactions<<endl;
}

};
#endif

and here is my main:

Code:

#include <iostream>
#include "Account.h"
using namespace std;

class functions : public Account
{

    public:

void PrintStatement(void)
{
    Account acc;
    acc.get_data();
}

int main()
{
    Account acc;
    functions func;


    char fname[20];
    char lname[20];
    float sinnum;
    int acctype;
    int numtrans;

    cout<<"Please enter the client's first name"<<endl;
    cin>>fname;
    cout<<"Please enter the client's last name"<<endl;
    cin>>lname;
    cout<<"Please enter the client's sin number"<<endl;
    cin>> sinnum;
    cout<<"Please enter the 1: for chequing or 2: for savings"<<endl;
    cin>>acctype;
    if (acctype !=1 && acctype !=2)
    {
        cout<<"Invalid account type, Please enter the 1: for chequing or 2: for savings"<<endl;
        cin>>acctype;
    }
    cout<<"Please enter the client's transaction number"<<endl;
    cin>>numtrans;

    acc.set_data(fname, lname, sinnum, acctype, numtrans);

    acc.get_data(); //it works here

    func.PrintStatement(); //here it doesnt work


    return (0);
}

Thank you very much for your help. I am very new to this.

Code:

void PrintStatement(void)
{
    Account acc;
    acc.get_data();
}

Change the above function to as you are already inheriting Account class:

Code:

void PrintStatement(void)
{
    get_data();
}

There is the incidental problem I can tell, visually, that your code, as posted, will not compile, but I assume that is an error in your copy and paste.

Agree with you. Semicolon is missing before main I guess...
