You can read a file step by step using the following code:
int ch;
while ((ch = fgetc(file)) != EOF) {
putchar(ch);
}
This special character might be the EOF.

From the man page for fgetc:
RETURN VALUE
fgetc(), getc() and getchar() return the character read as an
unsigned char cast to an int or EOF on end of file or error.
So you should check for feof before you use the return value of fgetc or you will print out the EOF character:
while(1){
int c = fgetc(file);
if(feof(file)){
break;
}
printf("%c",c);
}
