How could I achieve gotoxy() in gcc

I am using gcc in ubuntu.so, I compile and execute in terminal. But In a online programming contest, they require the output as shown in diagram.

required output

For that, if I use TURBOC I can get it using conio.h using gotoxy() to get spiral format of output. But in Ubuntu , How could I achieve this?

Solution

  • Use the ncurses library.

    Here's an example, adapted from http://www.paulgriffiths.net/program/c/srcs/curhellosrc.html

    #include <stdlib.h>
#include <stdio.h>
#include <curses.h>

int main(void) {
    WINDOW * mainwin;

    /*  Initialize ncurses  */

    if ( (mainwin = initscr()) == NULL ) {
        fprintf(stderr, "Error initialising ncurses.\n");
        exit(EXIT_FAILURE);
    }

    move(10, 15);
    addch('X');
    refresh();

    getch();

    delwin(mainwin);
    endwin();
    refresh();

    return EXIT_SUCCESS;
}
