这些VC++程序的各行语句的作用是什么啊？我对C++真的看不懂，可是我是学计算机的，我真的很想学，加上现在又要写这一程序的论文，说出各行语句的作用，能实现什么……请问有没有人能帮助我啊！以下只是我负责的一小部分
#include"console.h"
#include"student.h"
#include"studentui.h"
CStudentUI theUI;
CStudentFile theFile("student.dat");
                                     // 定义命令函数
void DoAddRec(void);
void DoDelRec(void);
void DoListAllRec(void);
void DoFindRec(void);
void main()
{
    const int nItemNum=7;
    char*strItem[nItemNum]={"Add a student data record",
                            "Delete a student data record",
                            "_",
                            "List all data records",
                            "Find a student data record",
                            "_",
                            "Exit" };
    theUI_SetOptionsTitle("Main Menu");
    for(;;)
    {
        int nIndex=theUI_GetOptions(strItem,0,0,nItemNum);
        switch(nIndex)
        {
            case 0:
                DoAddRec();      break;
            case 1:
                DoDelRec();      break;
            case 2:
                DoListAllRec();  break;
            case 3:DoFindRec();  break;
            case 4:
                return;
        }
    }
}
void DoAddRec(void)
{
    CStudentRec rec;
    if(theUI.InputStuRec(rec))
    {
        theFile.Add(rec);
        DolistAllRec();
    }
}
void DoDelRec(void)
{
    CStudentRec rec;
    char strID[80],str[80]="No find the record of";
    strcpy(strID,theUI_InputBox("Input Deleted Student ID",0,0));
    if(strID)
    {
        int nIndex=theFile.Seek(strID,rec);
        if(nIndex>=0)
        {
            theFile.Delete(strID);DoLisAllRec();      }
        else
        {
            strcat(str,strID);
            strcat(str,"!")；
                    theUI.MessageBox("Notice",str,1);
                }
    }
}
void DoListAllRec(void)
{
    int nCount=theFile.GetRecCount();
    CStudentRec*stu;
    stu=new CStudentRec[nCount];
    theFile.GetStuRec(stu);
    theUI.DispStuRecs(stu,nCount);
    delete[nCount]stu;
}
void DoFindRec(void)
{
    CStudentRec rec;
    char strID[80],str[80]="No find the record of";
    strcpy(strID,theUI._InputBox("Input Finded Student ID",0,0));
    if(strID)
    {
        int nIndex=theFile=theFile.Seek(strID,rec);
        if(nIndex>=0)
            theUI.DispStuRecs(&rec,1);
        else
        {
            strcat(str,strID);strcat(str,"!");
            theUI._MessageBox("Notice",str,1);
            
        }
    }
}

阿哦

原来全部都是菜鸟，怎么都没有人知道的呢？看来也不过如此

楼主的代码都没贴完整，
#include"student.h"
#include"studentui.h"
至于作用，函数名已经说明了
