Using sizeof() on a parameter array

[Jim Seidman]

I ran into this using Microsoft C 6.00A, and wanted to know if this was
a bug in MSC or the way an ANSI C compiler really should work.  Consider
the following function:

void test(char param[80]) {
    char local[80];

    printf("sizeof(param) = %d\n", sizeof(param));
    printf("sizeof(local) = %d\n", sizeof(local));
}

Now, I thought that this should print out the same size for both, namely
80.  But according to MSC, local has a size of 80, and param has a size
of 2 (the size of a pointer).

The ANSI K&R doesn't address this issue explicitly.  Any definitive
answers on what should happen?
