lottery simulator

[jamesfarrow]

Chaps I have written a lottery simulator ( I think ), but I can't help thinking that my logic is not correct on the conditional statement.
Basically int main() I use an bool array set to false and a random number gen which then sets the elements to true for the six numbers.
I then loop through the bool array and when true set that number to corrsponding element of the vector to store the numbers.

I pass this vector as const to a function that repeats the above but compares the vectors and if they are not the same the function runs again and checks const vect and so on and son on..

Can anyone put a learned eye over it for me please to check if my logic is correct - I'd really appreciate it!

The program is only to show my friends that they are bettor of buying a beer with the 2 quid lol !!!

  #include <iostream>
#include <cstdlib>
#include <ctime>
#include<vector>


using namespace std;

//function to return true if lotto win
bool lottoWin( const vector<int>& myLine,unsigned long int& numberOfDraws );


int main(void)
{
	int size = 6; // for vectors to compare
	bool lotterynumbers[59]; //array to store genertated numbers
	vector<int> myLine(size);//vector to store 6 numbers
	//integers to be used in for and while loops and amount of balls
	int num,line,numberofballs = 59;
	

	unsigned long int numberOfDraws = 0;// pass by value to increment in fuction
	
	srand( time(NULL) ); // randomise seed
	line = 1; //number of balls in a line set to one and inc to <=6


	//set all elements in lottrynumbers array to false
	for ( int i = 1; i <= numberofballs; i++)
		{
		lotterynumbers[i] = false;
		}

		
	//generate 6 random numbers and set that element to true	
	while( line <= size)
		{
		num = 1 + (rand() % 59);
		if ( !lotterynumbers[num] )
			{
			lotterynumbers[num] = true;
			line++; //increment for stop condition of loop
			}
		}
		
	int counter = 1;//used for indexing vector to store numbers
	
	//loop through array and when it's true then put that value 
	//into vector myLine to pass to function later
	for ( int i = 1; i <= numberofballs; i++)

I apologize for the quality of the code - I am very new to C++, if anyone can show me improvements that would be appreciated as well!!!!
