The code compiles but does not record (or) show the data properly. It only displays the last entered data. I couldn't figure out what exactly is wrong.
I would really appreciate any help

Code:
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
#include <cstdlib>
#include <cstring>
#include<string.h>

using namespace std;

//prototypes:
void findEntry(fstream&);
void addNewEntry(fstream&);
char *encrypt(char *var);
char *decrypt(char *var);
void printData(fstream&);

struct Data
{
	char username[20], password[30], info[50], website[30];
};
int main()
{
	fstream ioFile("Record2.ros",  ios::out | ios:: in | ios::binary);
	if(!ioFile){
	          cout << "Error opening file! Aborting ...";
	          return 0;
	 }
	 ioFile.clear();
    int choice;
    bool ex = true;
    while(ex == true){
    //Menu:
    cout << " Main Manu\n 1-Add New Entry\n 2-Find an Entry\n 3-Print All Data\n 4-Exit";
    cout << "Enter your choice: ";
    cin >> choice;
    while(choice > 4 || choice < 1)
    {
         cout << "choose between 1-4: ";
         cin >> choice;
    }

    switch(choice)
    {
         case 1:
              addNewEntry(ioFile);
              break;
         case 2:
              //findEntry(ioFile);
              break;
         case 3:
              printData(ioFile);
              break;
         default:
              cout << "Exiting ..." << endl;
              ex = false;
              break;
    }
    }
    system("pause");
    ioFile.close();


    return 0;
}
void printData(fstream& ioFile)
{
	
	Data dataObj;

	ioFile.read(reinterpret_cast<char *>(&dataObj), sizeof(dataObj));
	ioFile.seekg(0L, ios::beg);//move to the first byte
	while(! ioFile.eof())
	{
		//ioFile.read((char *)&dataObj, sizeof(dataObj));

		cout << "Printing Data:" << endl; 								//Read & Write the Website info:

		cout << "Website: " << decrypt(dataObj.website) ;
																		//Read & Write the UserName:
		cout << "\tUser Name: " << decrypt(dataObj.username) ;
																		//Read & Write the Password:
		cout << "\tPassword: " << decrypt(dataObj.password);
																		//Read & Write the Info:
		cout << "\nInfo: " << decrypt(dataObj.info);
																		//Write Object to file:
		cout << endl;
		ioFile.read(reinterpret_cast<char *>(&dataObj), sizeof(dataObj));
	}

}

void addNewEntry(fstream& ioFile)
{
    //ofstream ofs("Records2.ros", ios::binary);

    Data dataObj;
    char temp[100];
    cout << "New Entry" << endl;
    											//Read & Write the Website info:

    encrypt(temp);
    strcpy(dataObj.info, temp);
    											//Write Object to file:
    ioFile.seekp(0L, ios::end);//Move to the last byte
    ioFile.write(reinterpret_cast<char *>(&dataObj), sizeof(dataObj));//write the record
    cout << "Entry Added!" << endl;
