Binary File to read Student name and number

[UltimateOtaku9621]

Hi everybody!

So basically I'm trying to enter some names and numbers of some students and append their data using a while loop. I am able to get the program to append their data without any problem:

  #include <iostream>
#include <fstream>
using namespace std;

const int MAX=100;

struct Student
{
	char firstname[MAX];
	//char lastname[MAX];
	int number;
	char module;
};

int main()
{
	fstream fileB;
	int loop=1;
	char choice;
	Student data;
	
	cout<<"Append some records\n";
	fileB.open("infile.dat",ios::out | ios::app | ios::binary);
	if(!fileB)
	{
		cout<<"CANNOT OPEN FILE\n";
		exit(-1);
	}
	while(loop)
	{
		cout<<"Enter student name: ";
		cin>>data.firstname;
		cout<<"Enter student data: ";
		cin>>data.number;
		fileB.write ((char *) &data, sizeof (Student));
		//fileB.seekp (0,ios::end);
		
		cout<<"Continue? ";
		cin>>choice;
		switch (choice)
		{
			case 'Y':
			case 'y':	loop = 1;
				 		break;
			case 'N':
			case 'n':	loop = 0;
						break;
			default:	cout << "Please choose the right option!" << endl;
		}
	}
	fileB.close();
}

The code for creating the binary file is in a separate code, which works without error as well.
Which is not a problem. However, when I want the program to read the binary file, using this code:

#include <iostream>
#include <fstream>
using namespace std;

const int MAX=25;

struct Student
{
	char name[MAX];
	int number;
	char module;
};

int main()
{
	ifstream fileB;
	int loop=1;
	char choice;
	Student data;
	fileB.open("infile.dat",ios::in|ios::binary);
	while(fileB.read((char *)(&data),sizeof(Student)))
	{
		//fileB.seekp (0,ios::end);
		cout<<data.number<<" "<<data.name<<endl;
	}
	fileB.close();
}

it came out like this:

0 StudentA 
4788208 -random line-
237263 **garbage variables**

0 StudentB
4788208
251625 **garbage variables** 

when it's supposed to be:

237263 StudentA
251625 StudentB

Did I miss out anything in one of the two codes?

first code:
const int MAX=100;
second code:
const int MAX=25;
