Halp again. C woes... >_> - jwstohr - Feb 26, 2009

Ok this time it is a simple thing that I just cannot "get".

I need to fill an array b[6] with random unique numbers 1-15. I can generate random numbers and everything just fine... I just cannot figure out a way to compare the generated number to the array already done to check if it is a duplicate. And of course if not a duplicate, put it in the array. Rinse and repeat.

Any ideas? Big Grin

Something like?:

Code:
int isDuplicate = 0;

int newNumber = your_random_number_function();

// check for duplicate

for(int i = 0; i < 6; i++)

{

    if(b[i] == newNumber)

    {

        isDuplicate = 1;

    }

}

if(!isDuplicate)

{

    // add to array here

}

that would all go into a loop function as well though, right? Looks like it should work. Will give it a shot Big Grin

Actually that was a small piece of the big program. The program had to print out a user specified number of bingo cards to a file. Yeah, my teacher is crazy. I was just stuck on that part, the other 174 lines I wrote myself. I think I am getting the hang of this. Tongue
