I have a quick question

How would i read in these numbers

Code:

1234,2345,3456,4568

from a .txt file without the commas?

Code:

fscanf("%d,", &a);

and have a loop to keep on reading?

something like this

Code:

while ( (fscanf(id, "%d,", &existId)) != EOF)
	{
		if(existId == userId)
		{
			printf ("Login Success\n");
			return VALID;
		}
	}

In this case I'm comparing the read in ID to another ID that a user inputed

Yep, you can do that too...
But if you already knew how you wanted to do it, why did you bother to ask?

Ahhh ... Next time, try looking in your C Library documentation first.
Knowing where and how to look stuff up when you need it is a very valuable skill for a programmer.
