invalid source character: <0xffffff80>

[patso]

Hey guys, I have this program done but it is saying that I have an invalid source character: <0xffffff80> on line 71. I don't get it, i have every other one the exact same?

#include <stdio.h>

int main (void)
{
int number;
int n0 = 0;
int n1 = 0;
int n2 = 0;
int n3 = 0;
int n4 = 0;
int n5 = 0;
int n6 = 0;
int n7 = 0;
int n8 = 0;
int n9 = 0;


FILE *dPtr;

if ((dPtr=fopen("data.txt", "r"))==NULL){
        printf("File could not be read\n");
        }

else{
        printf("Enter the numbers:\n");
        fscanf(dPtr,"%d", &number);

        while (number != -1){
//      printf("%d\n", number);
        fscanf(dPtr,"%d", &number);


if (number <= 10)
n0++;
else
if (number <=20)
n1++;
else
if (number <=30)
n2++;
else
if (number <=40)
n3++;
else
if (number <=50)
n4++;
else
if (number <=60)
n5++;
else
if (number <=70)
n6++;
else
if (number <=80)
n7++;
else
if (number <=90)
n8++;
else
if (number <=100)
n9++;
}   
fclose(dPtr);   
}

printf("Range\tFrequency\n");
printf("0-10\t%d\n11-20\t%d\n", n0, n1);
printf("21-30\t%d\n", n2);
printf("31-40\t%d\n", n3);
printf("41-50\t%d\n", n4);
printf("51-60\t%d\n61-70\t%d\n", n5, n6);
printf("71-80\t%d\n81-90\t%d\n", n7, n8);
printf("91-100\t%d\n", n9);

return 0;
}

i just don't understand where i went wrong.

does any one know why this isn't working. I mean i am sure it is hard for you guys to compile because you don't have the program that writes the data. You just have the program that reads it. But is there any reason why this isn't working properly?

I found the problem, thanks to those who viewed the thread. I don't know why I did that incorrectly. Have a good night.!
