School Fee Enquiry System in C++

The project's code is written in the C++ programming language. Speaking about the system, the user may explicitly examine a student's fee slip for a class, change the school's fee schedule, and also view the school's fee schedule as a list. The following features are available as menu options:

FEE SLIP: This feature shows the fee slip for a specific student from the class that the user has selected.
MODIFY: This feature changes the class's pricing schedule. The user can alter the costs for different fields.
LIST: This feature lists the total costs for all of the school's classes.
HELP: This feature lists each menu's features.
QUIT: This command ends a running program.

Program Breakdown

#include <iostream>
#include <windows.h>
#include <fstream>
#include <cstring>
#include <cstdlib>
#include <cstdio>
#include <cctype>
#include <conio.h>
#include <ctime>
#include <dos.h>
#include <iomanip>

We will include the necessary files to support our code of the project in C++ without facing any type of error.

Fstream: library used to make new files, write information to existing files, and read data from existing files.

dos.h: This library includes routines for handling interrupts, making sound, handling dates and times, etc. It is exclusive to Borland and functions with compilers like Turbo C Compiler.

iomanip: To set the basefield flag, use this. To set the fill character, use this. It is applied to decimal precision settings. Field width is set with it.

class DRAW
{
 public :
 void LINE_HOR(int, int, int, char) ;
 void LINE_VER(int, int, int, char) ;
 void BOX(int,int,int,int,char) ;
} ;

To create or draw the borders for our school fee enquiry system in which all the content like fee slip, modify help and list will be present will be done with the help of the class draw having data members such as LINE_HOR, LINE_VER and 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);
}

The structure of the fee class will look like the above code having float tuition, ac, science, computer, and activity. To modify the fee record of the system a function named MODIFY_RECORD() will contain addition, modification, FEE_SLIP, LIST, and HELP.

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 ( ) ;
 break ;
 case ' L ' : fee.LIST ( ) ;
 break ;
 case ' H ' : fee.HELP ( ) ;
 break ;
 case ' Q ' : exit ( 0 ) ;
 break ;
 default : gotoxy ( 33 , 40 ) ;
 cout < < " Illegal Choice Press any key to return to Main Menu " ;
 getch ( ) ;
 mainmenu ( ) ;
 }
}

The main menu of the system will be containing some features of the system to select by a user and having switch case like F for opening fee.slip(), M for fee.MODIFICATION(), L for fee.LIST(), H for fee.HELP() and Q for exit(). If the user press key rather than these mentioned key the system will flag an error "Illegal Choice Press any key to return to Main Menu".

void DRAW :: LINE_HOR(int column1, int column2, int row, char c)
{
 for ( column1; column1<=column2; column1++ )
 {
 gotoxy(column1,row) ;
 cout <<c ;
 }
}

The function LINE_HOR will responsible to create a horizontal line for the menu of the system

void DRAW :: LINE_VER ( int row1 ,  int row2 , int column , char c )
{
 for ( row1 ; row1 < = row2 ; row1++ )
 {
 Gotoxy ( column , row1 )  ;
 cout < <  c ;
 }
}

The function LINE_VER will responsible to create a horizontal line for the menu of the system

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 ) ;
}

The above function uses the functions LINE_HOR and LINE_VER to create a box structure for the menu of the system.

 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 ) ;
}

If a user in the middle of the system wants to edit the fee structure of the school than the above code will help. It will open the data file of the system to do the permanent changes by using the MODIFY_RECORD function.

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 ( ) ;
}

If a user of the system want to list down the fee structure of each classes than the above code will help. It will display the list of the classes and the tution, ac, science, computer and activity fees structure.

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 ( ) ;
}

The above code functionality is to display the fee structure including the tuition, science, computer and other activities and also the annual charges.

The above code functionality is to print the fee slip of the student name entered by the user. The system will flag a message saying "ENTER NAME OF THE STUDENT", the system will search the name in the data file of the system and print the fee slip of the user.
