Store and eliminating garbage values - c

Question

Everytime I try to run the code it'll print out the contents of the file, however it will print out a garbage value at the end which I don't know how to get rid of. I am supposed to to store the contents of the file into an array, however I am a bit confused on how to do that???
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
char filePrinter(char*arr)
int main (int argc, char**argv)
{
char fileArray[150];
if(argc !=2)
{
printf("Invalid Entry. Please Enter name of program followed by input filename\n");
}
filePrinter(fileArray);
return 0;
}
char filePrinter(char*arr)
{
int i;
FILE*file;
i=0;
file=fopen("assests/room.txt","r");
if(file == NULL)
{
printf("Could not open file\n");
exit(-1);
}
else
{
while(0 ==feof(file))
{
i=fgetc(file);
printf("%c", i);
}
}
fclose(file);
return i;
}
file content:
10x16 ds5 h6,5 g7,8 p3,3
10X16 de4 h5,7 g9,2
10X16 dw6,h2,3 m6,7
10X16 dn3,h2,4 p2,3
10X16 de2 h9,9 m4,5
10X16 dn8 h4,5 g1,1*/

Answer 1

feof returns true if the last call to a read operation hit EOF. You'd want to test it after the fgetc call. Or, even better, just check whether fgetc returned the special value EOF.
(A FILE * has an "end-of-file marker" that says whether some read operation has hit EOF. Read operations set the "end-of-file marker" upon hitting EOF. Before you've hit---meaning tried to read past---the end of the file, that "end-of-file marker" is clear.)

Answer 2

Timing is bad than look at the beginning of the loop by feof because EOF occur in fgetc.
replace to
while(EOF!=(i=fgetc(file))){
printf("%c", i);
}
int filePrinter(char*arr){
int i = 0, ch;
FILE*file;
file=fopen("assests/room.txt","r");
if(file == NULL) {
printf("Could not open file\n");
exit(-1);
} else {
while(EOF!=(ch=fgetc(file))) {
//printf("%c", ch);
arr[i] = ch; //*arr++ = ch;
++i;//i : range check
}
arr[i] = '\0';
}
fclose(file);
return i;
}

Answer 3

I think the code should be:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void filePrinter(char*arr);
int main (int argc, char**argv)
{
char fileArray[150];
memset(fileArray, 0, sizeof(fileArray));
if(argc !=2)
{
printf("Invalid Entry. Please Enter name of program followed by input filename\n");
}
filePrinter(fileArray);
return 0;
}
void filePrinter(char *arr)
{
int c = 0, j = 0;
FILE* file = NULL;
file=fopen("assests/room.txt","r");
if(file == NULL)
{
printf("Could not open file\n");
exit(-1);
}
else
{
while (1)
{
c = fgetc(file);
if (c != EOF)
{
arr[j++] = c;
}
else
{
break;
}
}
}
fclose(file);
return;
}
