Thread: Simon Game w/ C

Hey! I'm currently designing a program which allows the user to play Simon on a hardware module. I'm not so sure why my code doesn't work. Would anyone be willing to help me out? It says that there is an error regarding the colornum variable in the int press(void) function.

Sorry if this thread seems stupid or anything; I'm an extremely amateur C programming student!

Below is my program:

Code:

/*
Simon Game
*/
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#include <Windows.h>
#include <DAQlib.h>
#include <time.h>
#include <math.h>


#define ON 1
#define OFF 0


#define Green 0
#define Red 1
#define Yellow 2
#define Blue 3


#define GreenLED 0
#define RedLED 1
#define YellowLED 2
#define BlueLED 3


#define GreenButton 0
#define RedButton 1
#define YellowButton 2
#define BlueButton 3


#define second 1000


#define TRUE 1
#define FALSE 0


void game(void);
void zzz(int index);
int press(void);


int main(void)
{
    int setupNum;
    printf("Please enter 0 for the Hardware, 6 for the Simulator: ");
    scanf("%d", &setupNum);
    if (setupDAQ(setupNum) == TRUE)
    {
        /* Stopped for one second to allow everything to load and user to get ready*/
        Sleep(second);
        game();
    }
    else
    {
        printf("Error intializing DAQ...");
    }
    system("PAUSE");
    return 0;


}


void game(void)
{


    while (continueSuperLoop() == TRUE)
    {
        int index;
        int count;
        index = 0;
        int NumNum = 5;


        /* Test that it does enter the Super Loop, and turns each light on, and then off after 1 second, one by one. */
        for (count = 0; count <= 3; count++)
        {
            digitalWrite(count, ON);
            Sleep(second);
            digitalWrite(count, OFF);
        }


        while (index < NumNum)
        {

            {

                pressed = press();

    return colornum;

Thanks for noting that out! I'll attach the install files on!

Hey! the install file is on this link (for the DAQlib.h)

thanks!!
