Re: random number guess

I got the enter void GetBet(int money, int& bet) function to work. it turns out that i called the int bet twice and then instead of using the while i used the if statement and it ran. Thanks

Re: random number guess

now I'm getting a bunch of error messages. now the program is saying that all of my varables are undefined and that my GetGuess function definition is illegal.
What is wrong with the guess function?

You have a brackets problem and a do loop that starts but never ends and thus return 0; and void PrintHeading(int money) are inside that do-loop that has a while that supposedly ends it, but in fact does not due to the lack of a bracket. If you format your code so that the brackets line up with each other and the do lines up with the while from an indentation standpoint, you will spot this much sooner. You need to take a step back and look at your whole program. You are coding in too many of the details of the program and the functions without looking at the overall program structure and what should go where and what function does what. Every opening bracket has a closing bracket. Every "do" needs a "while" at the end. Carefully look at each of the function specifications and read the words that describe what the function is supposed to do, what it doesn't do, what it returns, and the parameters it is passed. Also, every variable that you compare to another variable must be initialized to some value that makes sense before that comparison is made. I'm speaking in particular of this line 6 below. num and guess have completely random values. What does num represent? What does guess represent? How are they supposed to get their values? Take a step back and make sure you have a firm understanding of what exactly you want the program and the functions to do. You can't successfully code it until you know exactly what the goal is.

Re: random number guess

I don't know whether this is the error you are referring to or not, but it's an error that needs to be fixed:

C++ Syntax (Toggle Plain Text)
  1. 	/*
  2. 	GetBet prompts for and reads in a bet. The function performs all
  3. 	error checking necessary to insure that a valid bet is read in
  4. 	and does not return until a valid bet is entered.
  5. 	Parameters:
  6. 	money: the amount of money the player currently has
  7. 	bet: the bet chosen by the user
  8. 	*/
  9. 	void GetBet(int money, int& bet)
  10. 	{
  11. 		//int bet;
  12. 		if(( bet < money ) || ( bet > 0))
  13. 		{
  14. 		cout << " Enter bet : ";
  15. 		cin >> bet;
  16. 	}}

One, notice that the specification requires that the function does not return until a valid bet is entered. That means that there has to be some sort of a loop here. Currently you do not have one. You are on the right track with your condition, but not quite there.

C++ Syntax (Toggle Plain Text)
  1. ( bet < money ) || ( bet > 0)

A valid bet requires that bet is less than money (you may want to change < to <=) AND that bet > 0 (if bets of 0 are allowed, change > to >=). The key word here is AND. Currently you || in your condition, which means "OR", not "AND".

You are also doing a comparison before there is any value assigned to bet. You don't want to do that. You need to have the user enter a bet before comparing bet to anything. So you need a loop of some type in this function, where the loop is exited when he/she enters a valid bet, and you need to make sure not to check for a valid bet until the user actually enters a bet. I would also display an error message if the user enters an invalid bet so that the he/she knows what he/she did wrong.

Re: random number guess

You need to format so things line up, particularly when you are first learning, but really even as you get better. Things will pop out to you when you line things up and spaces things properly. It becomes very obvious what is inside a block of code and what is outside of that block. If you are not already using an IDE like Visual Studio Express (there are others out there too), it will simplify your life greatly to start using one. It has a formatting feature. One click of a button and your code is formatted the way you want it. Here's your code formatted and lined up. It will look far better in an IDE where the comments don't overflow onto the next line, so copy and paste it into one and it'll look better. Look at lines 89 and 90. They are not inside of any loop. Do you want them there?
