Thread: error opening the file...

If you are going for more fancier error interpretation you might want to a general error message generator... Especially use the constants that are predefined instead of hard coding "2", etc.

Code:

void check_cause(void) {
printf("Cause: ");
switch (errno) {
case ENOENT:
	printf("No such file or directory.\n");
	break;
case EACCES:
	printf("Permission denied.\n");
	break;
case EINVAL:
	printf("Invalid argument.\n");
	break;
case EMFILE:
	printf("Too many open files.\n");
	break;
default:
	printf("Error Code %d\n", errno);
	break;
	}
}

But have a look inside errno.h so see which conditions may possibly apply to your situation.

I don't know what to tell you about "numbers.txt" not working whereas "rr.txt" does. It's impossible.

Been a while since I actually hard coded a file path, though, so I may be wrong.

Not on Windows, no.

Code:

file = fopen("C:/Documents and Settings/ROHAN/Desktop/numbers.txt","r");
or
file = fopen("C:\\Documents and Settings\\ROHAN\\Destkop\\numbers.txt","r");

Code:

int myatoi(const char *str)
{
	int result = 0;

	while(isdigit(*str))
	{
		result *= 10;
		result += *str - '0';
		//printf("\n%c \t%d", *str, *str);
		str++;
	}
                printf("%d\n", result);
	return result;
}

I think your code is working right... your output is just a little misleading.

No. Only the command interpreter requires that.
