가장 높은 점수를 얻은 학생 정보가 표시됩니다.

Question

여기에 학생의 수 (n)에 대한 최고 점수를 알아 내고 학생에게 정보를 표시하는 방법에 문제가 있습니다. 불쾌한 정보에 신경 쓰지 마십시오. 코드가 너무 길어서 죄송합니다. 도움을 주시면 감사하겠습니다. 감사합니다.

Answer 1

그래서 나는 당신이이 라인에 무엇을하려고 확실하지 오전 : s[i].total = s[i].q1 + s[i].q2 + s[i].mid + s[i].final. 하지만 당신의 방법을 약간 수정했습니다.

void max(struct student s[]) 
{ 
    int i, max, id; 
    s[0].total = s[0].q1 + s[0].q2 + s[0].mid + s[0].final 
    max = s[0].total; 
    id = s[0].id; 

    for (i = 1; i < size; i++) 
    { 
     s[i].total = s[i].q1 + s[i].q2 + s[i].mid + s[i].final 
     if (s[i].total > max) 
     { 
       max = s[i].total; 
       id = s[i].id; 
     } 
    } 

    printf("\nHighest total score is %d belongs to student ID (%d)", max, id)//\\problem 
} 

그래서이 솔루션에는 학생 ID를 기반으로 할당 된 ID가 추가되었습니다. ID가 갱신 된 새로운 최대 값이 발견되면. Max는 첫 번째 학생 합계로 초기화됩니다. 이런 식으로 일할 수 있습니까?
