Pushing Values (First In, First Out)

Question

How can you push a value to the next place when a new value is entered? Is there another way?

This is my program:

< START >

#include<iostream.h>
#include<conio.h>
#include<stdlib.h>

void main(){
clrscr();
int dDigit01 = 0;
int dDigit02 = 0;
int dDigit03 = 0;
int dDigit04 = 0;
char choice;

OVERAGAIN:
cout << "ÉÍÍÍËÍÍÍËÍÍÍËÍÍÍ»\n";
cout << "º º º º º\n";
cout << "ÈÍÍÍÊÍÍÍÊÍÍÍÊÍÍͼ\n";

gotoxy(3,2); dDigit01 = getche();
gotoxy(3,2); dDigit02 = getche();
gotoxy(7,2); cout << dDigit01;
gotoxy(3,2); dDigit02 = getche();
gotoxy(7,2); cout << dDigit01;
gotoxy(11,2); cout << dDigit02;
gotoxy(3,2); dDigit02 = getche();
gotoxy(7,2); cout << dDigit01;
gotoxy(11,2); cout << dDigit02;
gotoxy(15,2); cout << dDigit03;

cout << "\n\nDo you want to try again to insert numbers; 1 or 0.";
cout << "[A] - Start Again | [B] Exit\n";
choice = getche();

switch (choice) {
case 'A' | 'a':
clrscr();
goto OVERAGAIN;
case 'B' | 'b':
exit(0);
}

getch();
}

< END >

So all I wanted is when I enter 1201, it will represent 1021.

Answer 1

As far as I could understand, you want to reverse the number 1201 to 1021. Is that correct?

Now, do you want to implement a queue for this?

Or all you have to do is reverse a standard int number? Or perhaps you want to type the numbers right to left? Eg -

1 0 2 1
// This was the screen when you
// typed 1021.

Ill help but I am unable to understand what you need to do here. I think the last one is what you want, as you used cursor placing functions.
