Can't find out why my program won't read analog values (Using MCP3004) [closed]

Question

I am using wiringPi and C. I have a flame sensor and a MCP3004 ADC. Here is the program that I wrote, but I can't figure out why it won't read the analog values from the flame sensor.

#include <wiringPi.h>
#include <mcp3004.h>
#include <stdio.h>
#include <stdlib.h>

#define BASE 200
#define SPI_CHAN 0

int main(void) {

int channel;
int x;

if (wiringPiSetup () == -1)
    exit(1);

mcp3004Setup(BASE, SPI_CHAN);
for (channel = 0; channel<8; ++channel) {
    x=analogRead(BASE+channel);
    printf("%d\n",x);
    delay(1000);
}
return 0;
}

My program runs but it just outputs 0s. The wiring is correct and the sensors and MCP3004 work fine, I tested it with a python program and it gets the job done.

So the only problem is in my C code.

The link here may help. They have the wiring shown pretty clearly and example programs for Python and C users.
