Thread: Pointer questions

OK here is my program

Code:

#include<stdio.h> /* fprint, fscanf, fclose, fopen  definitions */
      
int main(void)
   
{
 
  FILE *inp, /* input file pointer */
       *outp; /* output file pointer */
   
  int input_status, /* status of input */
      score, /* current score */ 
      largest, /* largest score */
      smallest; /* smallest score */
   int max=0; /* maximum score */
   int min=0; /* minimum score */
   
   /* open input and output files */
   inp = fopen (  "scores.dat" , "r" );
   outp = fopen (  "results.dat", "w" );
        
   fprintf (outp, "   Scores\n");
   fprintf (outp,  "   ------\n");

   input_status = fscanf ( inp, "%d", &score );

   max = score;
   min = score;

   while ( input_status == 1 ){
        fprintf ( outp, "   %d\n", score);
        if (max < score)
           largest = score;
        if (min > score)
           smallest = score;

        max = score++;
        min += score;
        input_status = fscanf ( inp, "%d", &score);


   }

/*   if ( input_status != 1)
   {
        fscanf ( inp, "%d", &score);
        printf ( "\nError in input of %d", score);
   } */
   if (input_status != 1)
   {
        fscanf ( inp, "%d", &score);
        fprintf( outp, "The highest score is %d\n", max);
        fprintf( outp, "The lowest score is %d\n", min);
   }
   /* closes files */
        
   fclose (inp);
   fclose(outp);
   return(0);
}

I want my output to display the largest and the smallest numbers. Now I know that this part

Code:

        max = score++;
        min += score;

is wrong. But I don't know what to put to get what I want?

well, u have upgrade the max and min value as soon as u get the value which is greater/lesser than score

Code:

if (max < score)
           max = score;
        if (min > score)
           min = score;
