cashiering program for my project., this cashiering program is Mc Jollibee....

[marienetteortiz]

hello..
I make a cashiering program but I dont know how would this program go back after the transaction..
this is the program I made...

#include<iostream.h>
#include<conio.h>
main()
{float a, b, c, d, CD=50, FF=25, SD=15, AM, T, Vat, AD, CH, TCR, TFF, TSD;
 textbackground(Lightmagenta);
 clrscr();
 textcolor(RED);
 gotoxy(35,3)
 cprintf("MC JOLLIBEE");
 gotoxy(32,4);
 cprintf("Cashiering System");
 gotoxy(8,7);
 textcolor(RED);
 cprintf("PRODUCTS");
 gotoxy(30,7);
 cprintf("PRICE");
 textcolor("BLACK");
 gotoxy(7,9);
 crintf("Chicken w/ Rice");
 gotoxy(7,11)
 cprintf("French Fries");
 gotoxy(7,13);
 cprintf("Softdrinks");
 gotoxy(29,9);
 cprintg("50.00");
 gotoxy(29,11);
 cprintf("25.00");
 gotoxy(29,13);
 cprintf("13.00");
 textcolor(RED);
 gotoxy(62,14);
 cprintf("--------");
 gotoxy(52,16);
 cprintf("total");
 gotoxy(52,18);
 cprintf("10% Vat");
 gotoxy(52,19);
 cprintf("---------");
 gotoxy(46,20);
 cprintf("Ammount to Pay");
 gotoxy(52,22);
 cprintf("Cash");
 gotoxy(62,23);
 cprintf("---------");
 gotoxy(52,24);
 cprintf("Change");
 gotoxy(48,9);
 cin>>a;
 gotoxy(48,11);
 cin>>b;
 gotoxy(48,13);
 cin>>c;
 gotoxy(67,9);
 TCR=CR*a
 cout<<TCR;
 gotoxy967,11);
 TFF=FF*b
 cout<<TFF;
 gotoxy(67,13);
 TSD=SD*c
 cout<<TSD;
 gotoxy(67,16);
 T=TCR+TFF+TSD
 cout<<T;
 gotoxy(67,18);
 Vat=T*0.1;
 cout<<Vat;
 gotoxy(67,20);
 AP=T+Vat;
 cout<<AP;
 gotoxy(67,22);
 cin>>d;
 gotoxy(67,24);
 CH=d-AP;
 if(d<AP)
  cout<<"Invalid";
 else
  cout<<CH;
 getch();
 return 0;
}

and my problem is how can I put Date and how can I repeat this program to the next transaction of cashiering by adding "Do you want to go next Transaction? [y]es [n]o"

hope you can help me
thank you..

You need to use a loop. Probably a do-while loop. At the end of the loop you ask whether to continue and while the answer is yes you return to the start of the program.

You will also need to solve how to store data for multiple customers.

BTW: You are using the C++ cin>> but the rest of the program is written in C. I suggest you pick one language or the other and stick to that one.

where did put the loopings?

Here's the logic:

do
{
 
//  your code goes here
 
} while ( next transaction == yes );
 

I recommend you read up on loops. There are many examples on the Internet.
