You are given a file containing an unknown amount of numbers. Each number
is one of the numbers 1 to 9. A number can appear zero or more times and can
appear anywhere in the file. The number 0 indicates the end of the data. Some
sample data are:

5 3 7 7 7 4 3 3 2 2 2 6 7 4 7 7
2 2 9 6 6 6 6 6 8 5 5 3 7 9 9 9 0

Write a program to read the data once and print the number that appears the most in
consecutive positions and the number of times it appears. Ignore the possibility of a tie.
For the above data, output should be 6  5.

试了很多次都不对

#include <stdio.h>
int main (){
 int s,n=0;
 FILE *in=fopen("a.txt","r");
 fscanf (in,"%d",&s);
 while (s!=0){
  if (s=s) { n++; }
  else if (n<n) { n=n; }
   fscanf (in,"%d",&s);    }
   printf ("%d %d",s,n);
   fclose(in);
}
