Getting the ASCII value from stack top

[joatmon]

I have a std::stack like this:

stack<string> s;

I'm pushing single characters onto it and later want to retrieve the ASCII table value from the top of the stack. For example:

s.push("+");
cout << size_t(s.top());

I'm trying to get 43 to come out of this (43 is the ASCII value of the + sign), but I get an invalid conversion error on this. Anyone know why?

Thanks.

Well, that's because you pushing in std::strings. Try pushing in chars instead.

I was afraid you were going to say that. I'd have to re-write too much to make that conversion.

I got it to work like this:

cout << size_t(s.top()[0]);

Ugly, but effective.

Thanks!
