rand() help trying to loop it till it finds all numbers in range 4x

what code can i use to make a loop that will find random numbers in the rang of 1 - 13 till all numbers in that range are used 4 times

this is what i would use to just make a loop that finds random numbers

for (int x; x <= 52; x++) // loop till x = 52
{
srand((unsigned)time(NULL)); // seed rand
y += 1 + rand() % (13); //find a random number in the rang of 1 - 13
cout << y << endl; // display random number
}

Here's one way:

Code:

void test30()

{

        int test[13];

        srand((unsigned)time(NULL));

        for (int i=0; i<13; test[i++]=0) ;

        int count=0, p=0;

        while (count<52)

        {

                int r=rand()%13;

                if (test[r]<4)

                {

                        test[r]++;

                        count++;

                        printf("%2d ",r+1);

                        p++;

                        if (p>12)

                        {

                                printf("\n");

                                p=0;

                        }

                }

        }

}
