Reading from txt file in C

I am trying to read numbers in from a text file into an array, covert them into Celsius, then print them out. But when I read in the number 212, 32, -1 (on separate lines) for example, it only seems to read in memory locations of the first two numbers and doesn't do the conversion.

#include <stdio.h>

int GetInput(double fahrenheit[]);
void ProcessData(double fahrenheit[], int count, double celcius[]);
void PrintHeading(void);
void OutputResult(double fahrenheit[], int count, double c[]);


int main(void) {
    char c;
    int i;
    double fahrenheit[1000];
	double celcius[1000];
    int count;

    count = GetInput(fahrenheit);
	ProcessData(fahrenheit,count,celcius);
    OutputResult(fahrenheit,count,celcius);

    return 0;
} // main


/*
GetInput  read data Fahrenheit degree (double) from keyboard in a 1-dim array F[1000]. It returns # of data entered
*/
int GetInput (double fahrenheit[1000])
	{
    const int SENTINEL = -1;

    int count=0;
    
    while (scanf("%lf", &fahrenheit[count]), fahrenheit[count] != SENTINEL)	
	{
		printf("This code worked %.2lf\n",&fahrenheit[count]);
		printf("This is the count %d\n", count);
		count++;
		
    }

    return count;

	}	

/*
ProcessData convert from Fahrenheit degrees in fahrenheit[] to Celsius degrees celcius[]
*/
void ProcessData(double fahrenheit[1000], int count, double celcius[1000]){
	int i = 0;
		for (i =0; i<count;i++)
		{
		celcius[count] = (fahrenheit[count] - 32.00)/1.8;
		}
}


/*
PrintHeading print only headings like below
		Fahrenheit		Celsius
		_________		______

*/
void PrintHeading(void){

printf("          Fahrenheit     Celcius\n          __________     _______\n");

}


/*
OutputResult print all degrees under appropriate headings
*/
void OutputResult(double fahrenheit[1000], int count, double celcius[1000])
	{
	int i =0;

	PrintHeading();
	for (i=0;i<count;i++)
		{
		printf("              %d               %d\n ",fahrenheit[i],celcius[i]);
		}
	}
