Part 7: tic-tac-toe: problem solving

In part 6, we left the definition of is_winning_position as follows:

int is_winning_position(int x, int y, char c) {
    return 0;
}

In parts 6 and 7 we will write a tic-tac-toe console program that plays itself.

The goal is to learn how to understand and solve problems.

We know how to write functions now, but we've glossed over the other fundamental aspect of programming; the data.

We're going to write our own functions and learn how to grow code in small steps.

Now is probably a good time to start using a text editor designed for programming.

You can use whatever you like.

I use Sublime Text for miscellaneous editing, and the sample code in this series.

We skipped a detailed explanation of if statements and for loops in part 3 because they deserve a lot of attention.

If statements and for loops the two most important flow control statements in most programming.

These are probably the first thing beginners realize about programming.

The C programming language grammar is mostly made of statements and expressions.

Statements are the syntax for defining the main surface of code: functions, data and control flow.

In part 1, we had this line at the top of 1.c:

#include <stdio.h>

	[Python-Dev] sort() return value

	I'd like to explain once more why I'm so adamant that sort() shouldn't
	return 'self'.
