Thread: about recursion...

Code:

void PlayerRemove(int &totalstones)
/* remove a stone between 1-3 and check to make sure value of total is not 0 */
{
	int playerstones;
	cin>>playerstones;

	if ((playerstones>3)||(playerstones<1))
	{
		cout<<"Value must be between 1 and 3"<<endl;
		cout<<"How many would you like? ";
		PlayerRemove(totalstones);
	}

	if ((totalstones-playerstones)<=0)
	{
		cout<<"Value must be between 1 and "<<totalstones<<endl;
		cout<<"How many would you like? ";
		PlayerRemove(totalstones);
	}
	totalstones=totalstones-playerstones;//here is the problem i only want it to do the subtraction if the number is between 1-3
}

how does recursion work? does it finish the whole function or start a new one where it left off? and how should i change this so it wont subtract from total if the number is not between 1-3

Eh, I don't think what you're trying to do should be done with recursion.

Recursion calls the same function with a different value (HOPEFULLY THERE'S AN EXIT CONDITION SOMEWHERE), and will finish up the rest of the function after the recursive call after the 'other' functions have executed.
