Department Management System In C
32 minute read
Introduction :-
This little undertaking in C Department Store Management System is a straightforward control center assembled application without realistic. In this undertaking, you can deal with a regular 'design wear' retail chain. You can add merchandise, alter products, search, erase and show the merchandise.
Document taking care of has been utilized to record the data (rate, amount, name and code) of the additional products. You can look through the merchandise by rate, code or amount. Also, comparable goes for show; you can show the things by amount, rate or code.
The source code for this scaled down project is finished and absolutely mistake free. It is incorporated in Code::Blocks with gcc compiler. Dissimilar to other C program source codes, I haven't showed the source code for this small undertaking on Department Store Management System in C here in light of the fact that it's excessively long – more than 800 lines.
Functions used in Department Store Management System:
I have essentially partitioned the capacities utilized in this venture into four parent capacities. Also, those individual capacities have been portrayed in short remarks inside the source code.
1. Show capacities:
void curser(int);
void dbill();
void d_mainmenu();
void display(rec *,int,int);
void window(int,int,int,int);
void dis_con();
void d_search();
void highlight(int,int);
2. Primary Menu capacities:
void bill() ;
void alter();
void add();
void del();
void exit();
3. Show sub-menu capacities:
void d_code();
void d_rate();
void d_quan();
void d_all();
4. Checking capacities:
void c_code(char[]);
int check(char[]);
void gotoxy (int x, int y) – I have been portraying this capacity in each C smaller than expected undertaking distributed on this site. You need to comprehend this capacity as it is perhaps the main one utilized in this Department Store Management little undertaking.
This capacity permits you to print text in any spot of screen. Utilizing this capacity in Code::Blocks requires coding, yet it tends to be straightforwardly utilized in Turbo C. Here is a code for this capacity in Code::Blocks
Code :-
#include<stdio.h>
