Re: Is cast operator unary or binary? How many operands?

How may operators and operands does (typename) expression has?

I'd say one operator, the cast operator, and two operands: typename
and expression.

But everywhere I read, cast is categorized as an unary operator. Why
is that? Is it just a syntax cotegory?

Thanks.

José María.

It has one argument: the expression, and a *result*
of type "typename"

When I write

(double)i;

I am conceptually calling

double TransformIntegerToDouble(int);

a function that takes ONE integer argument and outputs
a double number. Obviously there is no such a function
since the compiler inlines this cast when compiling, but
in some cases an actual function call will be generated.
