File writing problem

[Lozy]

    for(int i = 0; i<number_update; i++)
    {
    cout << endl;
    cout << "========="<<endl;
    cout << "Record number : " << i + 1 << endl;
    cout << "========="<<endl;

    cout << "Add a new customer's number" << endl;
    cin >> R4F[i].cus_number;
    outfile << R4F[i].cus_number << '\t';
    cin.ignore();


    cout << "Add a new customer's name" << endl;
    cin.getline(R4F[i].cus_name, 64);
    cout << "Name : " << R4F[i].cus_name << endl;
    outfile << (R4F[i].cus_name, 64, '\t');

    cout << "Add a new customer's hours used" << endl;
    cin >> R4F[i].cus_hour;
    outfile << R4F[i].cus_hour << endl;
    }

Why cant I write name to my txt file ? My txt shows cus_number and cus_hour only.
However, I can cout R4F[i].cus_name in my console instead.

Add a new customer's number
4948435
Add a new customer's name
hue hue
Name : hue hue //cout checking
Add a new customer's hours used

How have you defined cus_name ?

[Lozy]

struct record4function
{
    int cus_number;
    char cus_name[64];
    float cus_hour;
    float charge;
};

record4function R4F[12];

With char.

[Lozy]

I can now outfile name into my txt, by removing the size of array char in outfile
but now it doesn't tab after my cus_name.

outfile << R4F[i].cus_name, '\t';

Why are you using the comma operator here? Do you understand what the operator does in C++?

Thanks Mikey, solved my problem by changing , to <<
