I am trying to build a tic tac toe program for an assignment. My trouble is making a dynamic array, I am new to c and my understanding of pointers and malloc is still very limited. I would like a resource I could read or an explination of how malloc works for a 2d array. This is my code as right now, the malloc section is me trying to understand what I have been able to find on the internet so I know it is incorect.
#include<stdio.h>
/*
Program: tic tac toe
Author: charles haselden
Description: Plays tic tac toe either with a NPC or another player
Input: players, x or o
Output: gameboard after every round with positions played.
