converting a bool in an array of records to a string name?

[jpanther]

Hello everyone,
I have a file that looks like the following:
222-222-2222 1250 1
111-111-1111 700 0
This file is put into an array of records. The last number on each line is a bool, which indicates "1" is rented and "0" is available. When I go to display the contents on the array, it needs to display "rented" for 1 and "available" for 0. The program complies with no errors but only displays 1's and 0's.This is what I have so far. Any help would be appreciated. Thank you.

Filename is "RENTALS.txt"

Not actually tested,

	for (int count = 0; count < cnt; count++)
	{
		cout << fixed << showpoint << setprecision(2);
		cout << setw(13) << addApartment[count].phoneNum
			 << setw(17) << addApartment[count].rent;
                if (addApartment[count].rentalStatus == true)
                    cout << setw(12) << "RENTED";
                else
                    cout << setw(12) << "AVAILABLE";
		cout << endl;
	}
	return;

Thank you CodeWriter,
That works! I wonder why the way I had it set up didn't work. Can you not convert bool to a string character?

[IWishIKnew]

this is probaby better:

cout<< (addApartment[count].rentalStatus ? "RENTED" : "AVAILABLE")<< endl;

[jpanther]

Thanks for the reply. I am fairly new to programming, so I'm not too sure what the ? means. My guess is that it's using a bool and rented means true and available means false. Can you please clarify this?

[CodeWriter]

C++ provides the conditional operator (?:) that is closely related to the if/else structure.
The conditional operator is C++'s only ternary operator - takes three operands.
They form a conditional expression.

[jpanther]

That makes sense. Thank you for the link.

What I suggested was a ternary conditional operator. ( http://en.cppreference.com/w/cpp/language/operator_other )

The expression is: (a_bool ? eval_if_true : eval_else)

From www.cppreference.com:

The first operand of the conditional operator is evaluated and contextually converted to bool. After both the value evaluation and all side effects of the first operand are completed, if the result was true, the second operand is evaluated. If the result was false, the third operand is evaluated.
