关于c++.结构体使用的这个案例如何解决

Question

利用结构体定义以及函数调用，排序等代码解决该问题，其中六个学生的基本信息可以任意读入，最后输出表格类似的结果

Answer 1

需要定义一个学生信息结构，然后定义数组

typedef struct _student
{
    int stuno;
    char name[20];
    char gender;
    float math;
    float eng;
    float cpp;
    float ave;
}student;

void print(student *stu,int n)
{
    printf("%8s%20s%8s%8s%8s%8s%8s\n","StuNo","Name","Gender","Math","Eng","Cpp","Ave");
    for(int i=0;i<6;i++)
        printf("%8d%20s%8c%8.1f%8.1f%8.1f%8.1f\n",stu[i].stuno,stu[i].name,stu[i].gender,stu[i].math,stu[i].eng,stu[i].cpp,stu[i].ave);
}
void sorts(student *stu,int n)
{
    int i,j;
    student tmp;
    for(i=0;i<n-1;i++)
        for(j=0;j<n-i-1;j++)
        {
            if(stu[j].ave < stu[j+1].ave)
            {
                tmp = stu[j];
                stu[j] = stu[j+1];
                stu[j+1] = tmp;
            }
        }
}
int main()
{
    student stu[6];
    int i;
    for(i=0;i<6;i++)
    {
        scanf("%d%s %c%f%f%f",&stu[i].stuno,stu[i].name,&stu[i].gender,&stu[i].math,&stu[i].eng,&stu[i].cpp);
        stu[i].ave = (stu[i].math + stu[i].eng + stu[i].cpp)/3;
    }
    print(stu,6);
    sorts(stu,6);
    print(stu,6);

}
