我的答案

int read_students(Student students[9], int max){
    int i = 0;
    while(scanf("%s\t%s\t%s\t%s\t%s\n", 
            students[i].first_name,
            students[i].middle_name,
            students[i].last_name,
            students[i].cell_mobile_number,
            students[i].email_address)!=EOF){
        ++i;
        if(i>=max){
            break;
        }
    }
    return i;
