My Programm its a cootie game. Check this out http://en.wikipedia.org/wiki/Cootie_(game)!
My problem at the moment is that i need some more arguments for the function cootieComplete() and dont know how.

If you make all parts of the cootie global you can call cootieComplete without an argument:

But in your version the cootie can have more than 1body, endless eyes, endless legs and so on .. it it correct?

jRaskell (347)
Turn your cootie into a single object instead of a series of variables. A transparent struct, for example:
1
2
3
4
5
6
7
8
9
 
struct Cootie{
	int numBody;
	int numHead;
	int numBodypart_3;
	int numEye;
	int numBodypart_5;
	int numLeg;
};


Then you can create a single Cootie object the same way you would create an int or char.
 
 
Cootie newCootie;


And you could pass this to any of your functions as a single parameter, preferably as a reference or pointer, ie:

1
2
3
4
5
6
7
 
//function definition using reference
void applyRoll(int diceRoll, Cootie &c){
  if(diceRoll == 1) c.numBody++;
}

//Calling function
applyRoll(diceRoll, newCootie);


or:

1
2
3
4
5
6
7
 
//function definition using pointer
void applyRoll(int diceRoll, Cootie *c){
  if(diceRoll == 1) c->numBody++;
}

//Calling function
applyRoll(diceRoll, &newCootie);



Globals generally should be discouraged. Sometimes they're the least messy means of accomplishing a goal, but most of the time there are better ways.

If you're looking at having to pass a whole bunch of parameters around, you can probably put them in some form of container, whether that's wrapping them up into a discrete object (or a composite of multiple objects), or storing them in a generic container like a vector or list.

In this particular example, the ideal solution is to create a comprehensive cootie class that encapsulates all it's capabilities, as opposed to just a struct that container all the data

I need to solve it different!
MaikCAE and jRaskell thanxs for the help i really appreciate.

jRaskell I really like your solution but my prof want that the main looks like this

1
2
3
4
5
 
/*do {
   rollDice();
   applyRoll();
   printCootie();
while (!cootieComplete()) ;*/


We are not so far that we can use a class for the lab (its next). he wants what I use a lot of variables in the main cuz he dont want us to use globals.

So can you help me out, please?

If your variables are not global, then you need to pass them as parameters into the functions for those functions to have visibility to them (as I showed in my previous post). It's one way or the other.
You can still declare your variables in main(), then just pass them to the appropriate functions. If you store them in an array of ints, then you'd only have to pass one parameter instead of half a dozen, otherwise you're just looking at a large parameter list.

I was working the past few hours on the game and actually think its right but I get the message that 45 C:\Dev-Cpp\lab6.cpp expected `while' before "rollDice" which i dont get why.
