//输出成绩较高学生的学号，姓名和分数
#include<stdio.h>
int main()
{
    struct Student
    {
        int num;
        char name[20];
        int score;
    }student1,student2;
     scanf("%d,%s,%d",&student1.num,&student1.name,&student1.score);
    scanf("%d,%s,%d",&student2.num,&student2.name,&student2.score);
    printf("The higher score is:\n");
    if (student1.score>=student2.score)
        printf("%d,%s,%d\n",student1.num,student1.name,student1.score);
               else
               printf("%d,%s,%d\n",student2.num,student2.name,student2.score);
               return 0;



           }

为什么把scanf改为：scanf("%d,%d,%s",&student1.num,&student1.score,student1.name);
                    scanf("%d,%d,%s",&student2.num,&student2.score,student2.name);
就可以了呢？？？
