Reference vs. pointer

Question

What is the difference? Because this:

int Value = 50;
int *pValue = &Value;

*pValue = 88;

Answer 1

I agree with justin's answer and would like to clarify it with the tiniest example.

Suppose you don't quite remember the syntax of a 2D image geometric library: is it

bool BooleanOr( const Bitmap & input1, const Bitmap & input2, Bitmap * output );

or is it

bool BooleanOr( Bitmap * output, const Bitmap & input1, const Bitmap & input2 );

If in your company everybody uses pointers for outputs and const references for inputs it's virtually impossible to make a mistake: when you see calls such as

BooleanOr( thisBitmap, thatBitmap, & anotherBitmap );

you immediately know the syntax.
