would this be better or worse ???

GOOD POINT, never noticed that.

so how about this

            }
            while (check(lotteryBall, i));
 
            if(i == 8)

            {
            return true;
            break;
            }      
    }
}

ONE QUESTION: I THOUGHT I READ THAT IF YOU WANTED TO USE THE SRAND() FUNCTION YOU MUST INCLUDE THE DIRECTIVE: ctime. In this case I did not and it still works??

wouldn't something like this be better? I mean if c++ gives the find function why not use it?

{
	srand(time(NULL));
	unsigned int lotteryBall[7];
	unsigned int tempBall;
	unsigned int* search;
	for(int i=0;i<7;i++)
	{
		tempBall=rand() % 10 + 1;
		search= find(lotteryBall, lotteryBall+7,tempBall);
		if(search==lotteryBall+7)
		{
		//number is not found
		lotteryBall[i]=tempBall;
		cout<< lotteryBall[i]<<' ';
		}
		else{i--;}
	}
	cin.get();
	return 0;
}

#include <iostream> using namespace::std; int main() { srand(time(NULL)); unsigned int lotteryBall[7]; unsigned int tempBall; unsigned int* search; for(int i=0;i<7;i++) { tempBall=rand() % 10 + 1; search= find(lotteryBall, lotteryBall+7,tempBall); if(search==lotteryBall+7) { //number is not found lotteryBall[i]=tempBall; cout<< lotteryBall[i]<<' '; } else{i--;} } cin.get(); return 0; }

about ctime I am not sure but I do not include it and it works as well(at least with g++ on linux).
