완성 코드

#include <stdio.h>
#include <stdbool.h>
#include <stdlib.h>

int compare(const void* a, const void* b) {
    return (*(int*)b - *(int*)a);
}

int func_a(int scores[], int scores_len, int score) {
    for (int rank = 0; rank < scores_len; rank++)
        if (scores[rank] == score)
            return rank + 1;
    return 0;
}

void func_b(int arr[], int arr_len) {
    qsort(arr, arr_len, sizeof(int), compare);
}

int func_c(int arr[], int n) {
    return arr[n];
}
int solution(int scores[], int scores_len, int n) {
    int score = func_c(scores, n);
    func_b(scores, scores_len);
    int answer = func_a(scores, scores_len, score);
    return answer;
}
int main() {
    int scores[4] = { 20, 60, 98, 59 };
    int scores_len = 4;
    int n = 3;
    int ret = solution(scores, scores_len, n);

    printf("solution 함수의 반환 값은 %d 입니다.\n", ret);
}

 

결과

scores	scores_len	n	result
[20,60,98,59]	4	3	3
