Write a program in C that prints a tic$-$tac$-$toe board. Each square is to be $7\backslash$times $7,$ with $$#$$ marks. The $$X$$ is to be $5\backslash$times $5,$ composed of $$X$$s$,$ and placed in a square the coordinates of which are given as input.

Your program first prompts for, and reads, two integers separated by blanks or tabs between $1$ and $3$ inclusive; if either is not, print an error message giving both numbers and stating it is not a valid square and prompt for two numbers again. If you encounter an end$-$of$-$file, end the program. For example:

$>24$

$2,4$ is not a valid square; the numbers must be between $1$ and $3$ inclusive

$>2,4$

Illegal character in input $","$

$>$

The upper left square has co$-$ordinates $(1,1)$ and the lower right corner has coordinates $(3,3).$

On exit, your program returns $0.$

Here is an example input and output; the input is in red and the output in black.
