Finding the most frequent number in an array

I'm trying to see which number occurs the most in an array. I wrote this code, but its not outputting the correct numbers. Could someone tell me where I am going wrong

My logic:

1. It goes through the array to find numbers that are the same to itself. Then it adds +1 to each time it finds a number that is the same to itself (loop_freq_amt).

2. Then after it finishes the array it sees if the loop_freq_amt (the number's frequency it just checked) is greater than the current number which as the most frequency (freq_amt). If it is greater, then the freq_num gets replaced.

   int most_freq(int num_array[], int total_numbers) {
   
   int freq_num = 0;
   
   int freq_amt = 0;
   
   int i = 0;
   while(i <= total_numbers) {
   
       int loop_freq_num = num_array[i];
   
       int loop_freq_amt = 0;
   
       int j = 0;
       while(j <= total_numbers) {
   
   
           if (num_array[i] == num_array[j]) {
               loop_freq_amt += 1;
           }
   
           j++;
       }
   
       if(loop_freq_amt > freq_amt) {
           freq_num = loop_freq_num;
   
       }
       i++;
   }
   
   return freq_num;
   
   

   }
