c - How could I achieve gotoxy() in gcc

Question

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.

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?

Answer 1

Assuming because it is a contest and they don't want dependencies like ncurses you could try to do it in memory.

Set up 2 dimensional array of char - lines and columns - say 24x80. Write your own version of gotoxy() which assigns values into the proper cells. When done plotting, print out the array of lines.
