Answer 1

だから私はこの行で何をしようとしているのか分かりません：s[i].total = s[i].q1 + s[i].q2 + s[i].mid + s[i].final。しかし、私は少しあなたの方法を変更しました。

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 
} 

この解決策では、あなたの学生IDに基づいて割り当てられたIDを追加しました。 idが更新された新しいmaxが見つかったとき。 Maxは、最初の学生の合計で初期化されます。このようなことを試すことができますか？
