极客笔记C++ 学费查询系统
该项目的代码是用C++编程语言编写的。谈到系统，用户可以显式地查看学生在班级中的学费收据，更改学校的学费计划，以及查看学校的学费计划列表。以下功能可作为菜单选项使用：
- 学费收据： 此功能显示用户所选择的班级中特定学生的学费收据。
- 修改： 此功能更改班级的定价计划。用户可以修改不同领域的费用。
- 列表： 此功能列出学校所有班级的总费用。
- 帮助： 此功能列出每个菜单的功能。
- 退出： 此命令结束运行中的程序。

我们将包含必要的文件来支持我们的C++项目代码，而不会遇到任何类型的错误。
Fstream: 用于创建新文件，向现有文件写入信息，从现有文件读取数据的库。
dos.h: 该库包括处理中断、发出声音、处理日期和时间等功能的例程。它仅适用于Borland，并且与Turbo C编译器等编译器配套工作。
iomanip: 使用它来设置basefield标志。使用它来设置填充字符。它适用于十进制精度设置。使用它来设置字段宽度。
class DRAW
{
public :
void LINE_HOR(int, int, int, char) ;
void LINE_VER(int, int, int, char) ;
void BOX(int,int,int,int,char) ;
} ;
创建或绘制我们的学费查询系统的边框，其中包含费用收据、修改帮助和列表等内容，将使用draw类的帮助进行，该类具有数据成员LINE_HOR、LINE_VER和BOX。
class FEE
{
private :
int Class ;
float tuition, ac, science, computer, activity ;
void DISPLAY(int) ;
void MODIFY_RECORD(int, float, float, float, float, float) ;
public :
void ADDITION(void) ;
void MODIFICATION(void) ;
void FEE_SLIP(void) ;
void LIST(void) ;
void HELP(void);
}
上述代码的费用类的结构将包含float类型的tuition、ac、science、computer和activity。为了修改系统的费用记录，将包含添加、修改、FEE_SLIP、LIST和HELP的名为MODIFY_RECORD()的函数。
void mainmenu()
{
system ( " cls " ) ;
for ( li = 30 ; li <= 50 ; li++ )
{
gotoxy ( li , 14 ) ;
Sleep ( 30 ) ;
printf ( " * " ) ;
}
for ( li = 50 ; li >= 30 ; li-- )
{
gotoxy ( li , 30 ) ;
Sleep ( 30 ) ;
printf ( " * " ) ;
}
for ( lp = 15 ; lp < 30 ; lp++ )
{
gotoxy ( 30 , lp ) ;
Sleep ( 100 ) ;
printf ( " | " ) ;
}
for ( lp = 29 ; lp >= 15 ; lp-- )
{
gotoxy ( 50 , lp ) ;
Sleep ( 100 ) ;
printf ( " | " ) ;
}
gotoxy ( 15 , 10 ) ;
printf ( " Press the corresponding Keys for the desired action.. " ) ;
gotoxy ( 35 , 16 ) ;
printf ( " F: FEE SLIP " ) ;
gotoxy ( 35 , 19 ) ;
printf ( " M: MODIFY " ) ;
gotoxy ( 35 , 22 ) ;
printf ( " L: LIST " ) ;
gotoxy ( 35 , 25 ) ;
printf ( " H: HELP " ) ;
gotoxy ( 35 , 28 ) ;
printf ( " Q: QUIT " ) ;
choice = getch ( ) ;
ch = toupper ( choice ) ;
switch ( ch )
{
case ' F ' : fee.FEE_SLIP ( ) ;
break ;
case ' M ' : fee.MODIFICATION ( ) ;

case ' H ' : fee.HELP ( ) ;

break ;
default : gotoxy ( 33 , 40 ) ;
cout < < " Illegal Choice Press any key to return to Main Menu " ;
getch ( ) ;
mainmenu ( ) ;
}
}
系统的主菜单将包含一些系统功能供用户选择，并具有类似 switch case 的功能，如 F 用于打开 fee.slip()，M 用于 fee.MODIFICATION()，L 用于 fee.LIST()，H 用于 fee.HELP()，Q 用于退出()。如果用户按下除这些按键以外的按键，系统将标记错误”非法选择，请按任意键返回主菜单”。
void DRAW :: LINE_HOR(int column1, int column2, int row, char c)
{
for ( column1; column1<=column2; column1++ )
{
gotoxy(column1,row) ;
cout <
函数LINE_HOR将负责为系统菜单创建一条水平线。
void DRAW :: LINE_VER ( int row1 , int row2 , int column , char c )
{
for ( row1 ; row1 < = row2 ; row1++ )
{
Gotoxy ( column , row1 ) ;
cout < < c ;
}
}
LINE_VER函数将负责为系统菜单创建水平线
void DRAW :: BOX ( int column1 , int row1 , int column2 , int row2 , char c )
{
char ch = 218 ;
char c1 , c2 , c3 , c4 ;
char l1 = 196 , l2 = 179 ;
if ( c == ch )
{
c1 = 218 ;
c2 = 191 ;
c3 = 192 ;
c4 = 217 ;
l1 = 196 ;
l2 = 179 ;
}
else
{
c1 = c ;
c2 = c ;
c3 = c ;
c4 = c ;
l1 = c ;
l2 = c ;
}
gotoxy ( column1 , row1) ;
cout < < c1 ;
gotoxy ( column2 , row1) ;
cout < < c2 ;
gotoxy ( column1 , row2) ;
cout < < c3 ;
gotoxy ( column2 , row2) ;
cout < < c4 ;
column1 + + ;
column2 - - ;
LINE_HOR ( column1 , column2 , row1 , l1 ) ;
LINE_HOR ( column1 , column2 , row2 , l1 ) ;
column1 - - ;
column2 + + ;
row1 + + ;
row2 - - ;
LINE_VER ( row1 , row2 , column1 , l2 ) ;
LINE_VER ( row1 , row2 , column2 , l2 ) ;
}
上述功能使用LINE_HOR和LINE_VER函数为系统菜单创建一个框结构。
void FEE :: ADDITION ( void )

for ( int i = 1 ; i <= 12 ; i++ )
{
Class = i ;
tuition = 0.0 ;
ac = 0.0 ;
science = 0.0 ;
computer = 0.0 ;
activity = 0.0 ;
file.write ( ( char * ) this , sizeof ( FEE ) ) ;
}
file.close ( ) ;
MODIFY_RECORD ( 12 , 450 , 50 , 60 , 60 , 50 ) ;
MODIFY_RECORD ( 11 , 450 , 50 , 60 , 60 , 50 ) ;
MODIFY_RECORD ( 10 , 350 , 50 , 30 , 60 , 50 ) ;
MODIFY_RECORD ( 9 , 350 , 50 , 20 , 60 , 50 ) ;
MODIFY_RECORD ( 8 , 300 , 50 , 20 , 40 , 50 ) ;
MODIFY_RECORD ( 7 , 300 , 50 , 20 , 40 , 50 ) ;
MODIFY_RECORD ( 6 , 300 , 50 , 20 , 40 , 50 ) ;
MODIFY_RECORD ( 5 , 250 , 50 , 0 , 40 , 40 ) ;
MODIFY_RECORD ( 4 , 250 , 50 , 0 , 40 , 40 ) ;
MODIFY_RECORD ( 3 , 250 , 50 , 0 , 40 , 40 ) ;
MODIFY_RECORD ( 2 , 250 , 50 , 0 , 40 , 40 ) ;
MODIFY_RECORD ( 1 , 250 , 50 , 0 , 40 , 40 ) ;
}
如果系统中间的用户想要编辑学校的费用结构，那么上面的代码将会帮助。它将会打开系统的数据文件，使用MODIFY_RECORD函数进行永久性的更改。
void FEE :: LIST ( )
{
system ( " cls " ) ;
DRAW d ;
// textcolor ( MAGENTA ) ;
d.BOX ( 1 , 2 , 80 , 24 , 218 ) ;
gotoxy ( 27 , 3 ) ;
cout < < " TOTAL FEES FOR THE CLASSES " ;
d.LINE_HOR ( 2 , 79 , 4 , 196 ) ;
gotoxy ( 5 , 5 ) ;
cout < < " CLASS TOTAL FEES " ;
d.LINE_HOR ( 2 , 79 , 6 , 196 ) ;
d.LINE_HOR ( 2 , 79 , 22 , 196 ) ;
float total ;
int row = 8 ;
fstream file ;
file.open ( " FEE.DAT " , ios :: in ) ;
while ( file.read ( ( char * ) this , sizeof ( FEE ) ) )
{
total = tuition + ac + science + computer + activity ;
gotoxy ( 6 , row ) ;
cout < < Class ;
gotoxy ( 23 , row ) ;
cout < < total ;
row + + ;
}
file.close ( ) ;
gotoxy ( 5 , 23 ) ;
cout < < " Press any key to continue............. " ;
getch ( ) ;
mainmenu ( ) ;
}
如果系统的用户想要列出每个班级的费用结构，上述代码将会起到帮助作用。它将显示班级以及学费、空调、科学、计算机和活动的费用结构列表。
void FEE :: DISPLAY ( int tclass )
{
fstream file ;
file.open ( " FEE.DAT " , ios :: in ) ;
while ( file.read ( ( char * ) this , sizeof ( FEE ) ) )
{
if ( Class == tclass )
{
gotoxy ( 5 , 5 ) ;
cout < < " Class : " < < Class ;
gotoxy ( 5 , 7 ) ;
cout < < " ~~~~~~~~~~~~ " ;
gotoxy ( 5 , 8 ) ;
cout < < " Tution Fee : " < < tuition ;
gotoxy ( 5 , 9 ) ;
cout < < " Annual charges Fee : " < < ac ;
gotoxy ( 5 , 10 ) ;
cout < < " Science Fee : " < < science ;
gotoxy ( 5 , 11 ) ;
cout < < " Computer Fee: " < < computer ;
gotoxy ( 5 , 12 ) ;
cout < < " Activity Fee : " < < activity ;
break ;
}
}
file.close ( ) ;
}
以上代码的功能是显示费用结构，包括学费、科学、计算机和其他活动，以及年度费用。
