int main()
{
    int shuxue, yuwen ,wuli ,huaxue ,zongfen;
    int select;
    shuxue=138;
    yuwen=59;
    wuli=98;
    huaxue=100;
    zongfen=395;
    scanf("%d",&select);
    if(select==1)
    {
        printf("数学成绩是：%.0d\n" ,shuxue);
        return 0;
    }

    else if(select==2)
    {
        printf("语文成绩是：%.0d\n" ,yuwen);
        return 0;
