C Programming: Find maximum and minimun.

[TamaraKM]

Hi, I am a in a beginner c programming class and need help with a project. I need to find the minimum and the maximum for the following.


Candidate Results
Id J1 J2 J3 totalScore
4 2 0 3 5
3 3 4 10 17
7 9 1 0 10
1 5 0 7 12
13 6 10 5 21
2 6 5 1 12
6 0 8 4 12
5 7 9 9 25
8 0 2 5 7
9 7 7 6 20
10 1 6 2 9
12 4 9 0 13
11 0 3 6 9
13 Total Candidates
Average total score is 13.0







This is what I have so far.

#include<stdio.h>
main()
{
      FILE *inCanResults, *outCanResults;
      inCanResults = fopen("data2a.txt", "r");
      outCanResults = fopen("out2a.txt", "w");
      int ctr, idNum, j1, j2, j3, total, count, totalScore, e;
      float avg;       
      e=fscanf(inCanResults,"%d %d %d %d", &idNum, &j1, &j2, &j3); 
      printf("      Candidate Results\n");
      printf("Id    J1    J2    J3    totalScore\n");
      fprintf(outCanResults,"      Candidate Results\n");
      fprintf(outCanResults,"Id    J1    J2    J3    totalScore\n");
      ctr = 0;
      total = 0;
      
      while (e==4)
      {
         totalScore = j1 + j2 + j3;
         printf("%d %5d %5d %5d %9d\n", idNum, j1, j2, j3, totalScore);
         fprintf(outCanResults,"%d %5d %5d %5d %9d\n", 
                                   idNum, j1, j2, j3, totalScore);
         ctr = ctr + 1;
         count = count + 1;
         total = totalScore + total;
         e=fscanf(inCanResults,"%d %d %d %d", &idNum, &j1, &j2, &j3);
      }
      avg = total / ctr;
      printf("       %d Total Candidates\n", count);
      fprintf(outCanResults,"       %d Total Candidates\n", count);
      printf("       Average total score is %.1f\n", avg);
      fprintf(outCanResults,"       Average total score is %.1f\n", avg);
      printf("Top candidate is number %d with score of %d\n", 
                  idNum, totalScore);
      fprintf(outCanResults,"Top candidate is number %d with score of %d\n", 
                  idNum, totalScore);
      printf("Bottom is number %d with score of %d\n", idNum, totalScore);
      fprintf(outCanResults,"Bottom is number %d with score of %d/n", 
                  idNum, totalScore);
      fclose(inCanResults);
      fclose(outCanResults);
      system("pause");   
      }

The book we are using doesn't explain this very well so I would appreciate some help. Thank you!!

Since you aren't storing them all in memory as you read them, you will need to include checks for the values you have just read, and test whether or not they are bigger or smaller than what you already have.
