Guess if the next card is higher or lower?

Usually I can get through my homework assignments no problem...not sure why I am having trouble. I need to display a card (Ace-King...1-13) and the user needs to guess if the next card will be higher. Here is my code:

#include <iostream>

card = rand()%13+1;


if (card!=1 && card > lastcard && user == 0)
{
	right++;
}
else if (card!=1 && card < lastcard && user == 1)
{
	right++;
}

put<<fixed<<setprecision(2)<<right/5<<"% right."<<endl;

	return(0);

My RIGHT variable is coming out to 0 every time.

Thanks for the help.

Maybe (card < lastcard && user != 0) or (card > lastcard && user != 1) ?

I still cannot figure out how to make it so that the variable "right" will actually add 1 each time the user gets it right...

Perhaps it has something to do with my lastCard variable.

Anyone have any idea?

Try:

put<<fixed<<setprecision(2)<<double(right/5)<<"% right."<<endl;

Gah! Thank you! I had it set as an integer!
