Using the if statement with inputs

[ImaVampire]

I am receiving an error code saying that y, Y, n, and N are undefined. Although I know they are undefined I just want to use the user input for my if statements. I used the data type char for grad.

How do I make the if statement valid? I dont want the y's or n's to be variables but just user input.

cout << "Are you graduating this year? Y for yes or N for no";
	cin >> grad;

	if (grad != (y || Y))
	{
		gradfee = 00.00;
		if (grad != (n || N))
			cout << "Error! You must enter Y for yes or N for No.";
	}
	else
		gradfee = 35.00;

Those booleans in those if statements don't actually evaluate to how you think they do. You have to type out everything, and by everything I mean
if( grad != 'y' || grad != 'Y' )

Also I think you meant to put a single quote in there, due to them being characters, not variables.

I usually do it like this an Yes no Question:

char yesOrNo;

std::cout << "Do you like cats (y or n)? ";
std::cin >> yesOrNo;

...

And mark the thread as solved if you got it working.

edit: Thanks, YFGHNG.

Input operator goes the other way, bro. >_>
