how can a void function be called to the main, if there are no returns?

I wanted to create a function that retrieves all the information from previous functions within the same Class, and prints the values that were returned in the format of a bunch of cout statements, there is nothing for me to return in this PrintStatement() function, so I would create a void function, correct? My issue is in the int main(), I cannot cout a void function.

this is my account header file, and the function piece from my account.cpp file.

class Account {

public:
    //Object constructor
     Account(char firstName[], char lastName[], char sinNumber[], double balance, int accountType, int transactions);

    //Object operations
    double DepositAmt(double amount);
    double WithdrawAmt(double amount);
    void   PrintStatement();
    double getFinalBalance(double fbal);
    string getAccountType();
    double getTransactions (double Deposit, double Withdraw);

private:
    //Object properties
    char firstName[255];
    char lastName[255];
    char sinNumber[255];
    double balance;
    int accountType;
    int transactions;
};


void Account::PrintStatement()
{

        cout << "First Name:    " << firstName    << endl;
        cout << "Last Name:     " << lastName     << endl;
        cout << "SIN Number:    " << sinNumber    << endl;
        cout << "Account Type:  " << accountType  << endl;
        cout << "Final Balance: " << balance      << endl;
        cout << "Transactions:  " << transactions << endl;


};

the global variables have already been initialized.

What I've tried:

I originally tried to cout << account.PrintStatement() << endl; however I get an error C2679 (binary '<<' : no operator found which takes a right-hand operand of type 'void' (or there is no acceptable conversion)

I thought maybe changing things to apply to a string function instead would work, but instead I get a bunch of int conversion errors etc.

I'm unsure of what to do.

I am required to put these in a function just to be clear.

I tried using this question http://ift.tt/1DnkUJZ to help me, it made sense that the poster was using a reference, but I do not have that. Is there another way?
