Reverse Bubble Sort Algorithm in C using only while loop

I am trying to create a reverse bubble sort algorithm. It works but the first output is a big crazy number that i dont understand. The remaining outputs seem to be sorted in descending order. Where is my code wrong?

   #include <stdio.h>      void ft_rev_int_tab(int *tab, int size)    {     int i;     int j;      int k;         i = 0;       while (i < size)      {       j = 0;       while (j < size -i)         {           if (tab[j] < tab[j+1])                {                   k = tab[j];                    tab[j] = tab[j+1];                    tab[j + 1] = k;                }       j++;     }   i++;     }     }       int main(void)      {   int tab[] = {9, 320, 0, 113, 15};    int size = sizeof(tab) / sizeof(*tab);       ft_rev_int_tab(tab, size);     for (int i = 0; i < size; i++)       {      printf ("%d\n", tab[i]);     }      }
