Yes, but when you use printf() you have to declare the type of each
variable in the format string.  If you use C++ streams the compiler does
this for you.  I know of no other way to do something like this with a
variable number of arguments.

No.  Doing this tends to lead to unreadable code.  For example:  If I
overload the word 'or' as an infix operator, this sentence no longer has
the same meaning that I intended (this is because 'word' becomes 'w or d'.
Did you find the other 'word' in that sentence which contains 'or' yet?).
It also leads to nightmares for the parser (is '/+' an error or an overload
operator, etc.).

Learn about the language before you criticize it!!!  C++ has both
call-by-reference and call-by-value (the former being new with respect to C
and the latter being the same as passing an address in C), as well as a way
to have automatic dynamic type checking (if you want the additional runtime
overhead that's required).
