You'll need a PIC programmer. They can cost various amounts. I've seem some for hundreds of pounds and others for about £30.

Matthew wrote:Unlike the C++ rubbish, this nice C function should return 1 if the input is correct and there is one format specifier. It should return 0 if everything failed.

Matthew wrote:You can still make a calculator with a large part software. Why don't you try getting a PIC development kit (programmer/tester) and making simple programs with it. Then you might want to try interfacing with basic components on a breadboard and maybe you will someday want to make a home-made printed circuit board (Something experts do and requires the use of dangerous chemicals and extreme safety caution must be used).

Have you used electrical components before and do you know much about them?

void PlayerTurn(char board[3][3])
{
    int placement;
    int loop = 0;

    do
    {
        printf("\nWhere would you like to place an 'X'?\n> ");
        scanf("%d", &placement);

        switch (placement)
        {
            case 1:
            case 2:
            case 3:
            case 4:
            case 5:
            case 6:
            case 7:
            case 8:
            case 9:
                loop = 0;
                break;

            default:
                loop = 1;
        }
    } while (loop);
}

You need top change the while condition to "while(!loop)" so it ends when the loop variable becomes true (Use stdbool.h for boolean readability). Else change what the boolean becomes.

For nested breakages you can use gotos. This is another option to exit the loop. Simply use "while(1)" or "while(true)" when you exit loops in that fashion.

Matthew wrote:Goto is the only way to break out of nested loops and switch statements. It also allows you to do some other things like basic exception handling.

Matthew wrote:The break statement only breaks out of one loop or switch statement. You can't do several unlike PHP wonderfully does.
