我的第二篇博客,C++语言学生管理系统,由于个人原因NumberSum()没有写。。。,该程序==最大的亮点不是可以存储学生的数据,而是当你关闭程序,第二次打开后,以前写的数据还会存在==,如果你需要写一个学生管理系统,这个一定会让你眼前一亮!话又说回来,别人写的总归是别人写的,如果你有幸看了我写的,也希望你能够自己亲自写一遍!废话不多说,贴代码,源代码我也放到了下载,需要的赶紧去下载。

13.成绩统计(空)

14.显示现有学生的信息情况

15.输出用户自定义需要输出的内容

void SubjectJudge(int * number)
{
 cout << "姓名 学号 班级 ";
 for (int i = 0; i < 9; i++)

  if (*(number + i) == 1)cout << "语文 ";
  if (*(number + i) == 2)cout << "数学 ";

  if (*(number + i) == 4)cout << "政治 ";
  if (*(number + i) == 5)cout << "历史 ";
  if (*(number + i) == 6)cout << "地理 ";
  if (*(number + i) == 7)cout << "生物 ";
  if (*(number + i) == 8)cout << "物理 ";
  if (*(number + i) == 9)cout << "化学 ";
 }
 cout << endl;
}
