C++ :: Text File To Binary File

I want to convert a text file into binary file. I should create the text file by myself. I also use a structure for the components:

struct Data
{
int num;
char name[30];
};

I write information in the text file like this:

Data d;
cin >> d.num >> d.name;
fstream file("Name.txt");
file << d.num << d.name << '
';

If I have entered:
3 Steve
is easy to get this data. I just make another variables and get the data in them:

int num2;
char name2[30];
file >> num2 >> name2;

And everything is done. But what if I have this:

cin >> d.num;
cin.getline(d.name, 100);
file << d.num << d.name;

and the input is:
5 Steve Brown

I can get the number easy like before but how can I get the whole name? If I use:

int num2;
file >> num2;
char a[30];
file >> a;

I get only the first name "Steve". Can I get somehow and the second name in the same variable?
