Arrays and Functions

Consider:

void function(long n1[5]);

A function protoype.

what are the maximum number of values that I can change back in the main using the parameter I pass in??

For a single dimension array, the number in the brackets is absolutely meaningless - you may just as well leave it empty for all that the compiler cares.

Excellent Mats you really are a c maestro

Furthermore, does this mean that it is basically a pointer and I will only be able to alter what it points to?

Thanks

Yes you can alter it.
Usually, you also pass the size of the array to a function:

void show( int n[], int size)
{
    while (size--) printf( "%d ", *n++);
    printf( "\n");
}

It is a pointer yes. And you can alter anything related to that address [and if you really want to, and know where it is, you can even reach data outside of what it actually points to...]

I note that this is the C++ section, so ideally you should be using std::vector or std::tr1::array, rather than manually passing the size of an array. Unless you are using C, of course.
