Question

Need help with finding values in arrays. Where did I go wrong? (C Programming)

This is the input:

10
14 A 447 252 68 34 978
2 C 230 299 597 180 9
27 A 318 220 97 28 1317
32 C 563 450 547 112 28
8 C 669 260 200 36 171
11 S 179 45 1342 732 174
19 S 74 249 861 1165 6
21 A 757 240 97 119 2032
15 S 275 177 588 577 52
6 C 886 401 327 109 48

This is what the output should be:

A: 21 1171.00
C: 6 696.70
C: 32 578.00
S: 11 1094.20
S: 19 1046.50

This is my code:

float getRanking(char ch, int points[]);
int findMax(char key, char category[], int id[], float scores[], int n);

int main() {

int id[MAX];
char category[MAX];
int n, i, j;
int combat_score[SIZE];
float scores[MAX];
int m;

FILE *ifp = fopen("sample.txt", "r");

//Read in number of sets
fscanf(ifp,"%d", &n);

        //Read ID and category
        for (i=0; i<n; i++) {
        fscanf(ifp, "%d %c", &id[i], &category[i]);

       //Read 5 combat_scores
            for (j=0; j<SIZE; j++) {
            fscanf(ifp, "%d", &combat_score[j]);

}

scores[i] = getRanking(category[i], combat_score);

}

//insertionSort(category, scores, id, size);
//sort(category, scores, id, n);

m = findMax('A', category, id, scores, n);
printf("%c: %d %.2f ",category[m],id[m],scores[m]);

m = findMax('C', category, id, scores, n);
printf("%c: %d %.2f ",category[m],id[m],scores[m]);

m = findMax('S', category, id, scores, n);
printf("%c: %d %.2f ",category[m],id[m],scores[m]);

m = findMax('S', category, id, scores, n);
printf("%c: %d %.2f ",category[m], id[m], scores[m]);

fclose(ifp);

return 0;
}

int findMax(char key, char category[], int id[], float scores[], int n) {

    int i, loc= 0;
    float first=0;
    float second=0;
    float sec=0;

for (i=0; i<n; i++) {
sec = second;

        if (key == category[i]) {
           first = scores[i];
           second = scores[i];

            if (first < scores[i]) {
            second = first;
            first = scores[i];

}

            else if (sec < scores[i]) {
            second=scores[i];
            loc = i;
            sec=second;

}

return loc;

}

float getRanking(char ch, int points[]) {

float sum = 0;

    if (ch == 'C')
        sum += (points[0] * 5 + points[1] * 5 + points[2] + points[3] + points[4] * 2) / 10.0;
    else if (ch == 'S')
        sum += (points[0] + points[1] + points[2] * 5 + points[3] * 5 + points[4] * 2) / 10.0;
    else if (ch == 'A')
        sum += (points[0] + points[1] * 2 + points[2] * 2 + points[3] + points[4] * 5) / 10.0;

return sum;

}

This is my output:

A: 21 1171.00
C: 6 696.70
C: 6 696.70
S: 11 1094.20
S: 11 1094.20

Explanation / Answer

#include<stdio.h>
#define MAX 1000000
float getRanking(char ch, int points[]);
int findMax(char key, char category[], int id[], float scores[], int n);
