I tested your code with the changes I listed below so it works on SuSE
Linux. I was able to enter all the stock items in your list and list all
13 out.

Here are the changes I made to your program (only to replace the Windows
specific issues with Linux compatible code).

1.
#include <cerrno>
/***************** include unistd.h and termios.h for getch() ***/
#include <unistd.h>
#include <termios.h>
// Conio is a WINDOWS specific header.
// #include <conio.h> //for getch()

2. void cls(void) { system("clear"); } // so this works on Unix/Linux
3.
/********************************************************************
* Simulate the Windows conio function getch
*******************************************************************/
char getch()
{
int rv;
char ch;
int fd = 0; // force to stdin
struct termios oldflags, newflags;
/*********** Reset the terminal to accept unbuffered input ***/
/* get the current oldflags */
tcgetattr(fd, &oldflags);
/* make a copy of the flags so we can easily restore them */
newflags = oldflags;
/* set raw input */
newflags.c_cflag |= (CLOCAL | CREAD);
newflags.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);

/* set the newflags */
tcsetattr(fd, TCSANOW, &newflags);
rv = read(fd, &ch, 1);
/* restore the oldflags -- This is important otherwise
* your terminal will no longer echo characters
*/
tcflush(fd, TCIFLUSH);
tcsetattr(fd, TCSANOW, &oldflags);
return ch;
}
