If Else and || operator question

I'm trying to make a program which states the day of any date I use using Zeller's algorithm. I don't have the code with me right now. But when I try to write an if statement with an address and an or || operator, it doesn't compile. For example,

Code:

int getmonth (int *month, int *date)
{scanf ("%d/%d", month, date);
If ((*month==1 || *month == 2) && *date>=1 && *date<=31)
return 1;
else return 0;}

It gives an error for some reason saying that *month must be a modifiable variable. What could be wrong?

Must supply address for scanf

Code:

scanf ("%d/%d", &month, &date);

> I don't have the code with me right now.
So post it when you do have it.
Posting what you think you have from memory means we can only make guesses, and be no nearer the real answer.

> Must supply address for scanf
But they're already pointers, so that bit should be OK.

This is why we indent code...
It's also why you want a syntax highlighting editor...

Code:

int getmonth (int *month, int *date)
  {scanf ("%d/%d", month, date);
   If ((*month==1 || *month == 2) && *date>=1 && *date<=31)
     return 1;
   else 
     return 0;}

Check the first letter on the third line... there's your error.
