hi, i have an assignment to put 6 pseudo random numbers into an array to

simulate drawing 6 lottery numbers between 1-49. the code i have to do this

so far is listed below. i dont think its far off. im getting a recurring

error regarding the syntax of my main() function argument calling in

lottery_numbers[] array. so any help as to whats glaringly going wrong

here?? oh and some brief guidance on whats the easiest way to sort the

numbers into ascending order in the array before i cout << them.

p.s. i am aware from some replies to earlier posts that some of the things

like the includes' etc is a bit archaic but for the purposes of this

assignment, i dont really need it pointing out. cheers.

here's the code as it stands....

// lottery.cpp

// generates six pseudo-random numbers

// and displays them in ascending order.

#include<iostream.h> //c++ I/O

#include<stdlib.h> //standard function library

#include<conio.h> //getche()

#include<time.h> //time(), time_t

bool checknum(int num, int lottery_numbers[5])

{

for (int x=0; x <= 5; x++)

{

//check number is not equal to any other number already in array

//and is greater than zero.

if (lottery_numbers[x] == num || lottery_numbers[x] == 0)

{

return false; //the number is invalid. it is rejected.

}

}

return true; //the number is valid. it is accepted

}

void DrawNumbers(int lottery_numbers[5])

{

int num_count = 0; //counter for number of valid numbers found.

while (num_count <=5) //i.e. while all 6 numbers have not yet been drawn.

{

//initialise random number generator

time_t t;

srand(unsigned (time(&t)));

int num = (rand()*49); //generate a random number between 0 and 49

if (checknum(num, lottery_numbers)) //use checknum() to test validity

{

lottery_numbers[num_count] = num; //set current array element to

validated num.

num_count++; // move on to next element in array to fill.

}

}

}

void main(int lottery_numbers[5])

{

DrawNumbers(lottery_numbers[]); //'draw' the numbers into the array

for (int i = 0; i <=5; i++) // for each of the six elements of the array...

{

cout << lottery_numbers[i] << " "; //print out the contents to screen.

}

getche();

}
