bool equation

[thomas]

for c++ stl, is there any container or algorithm that can help
calculate result of a bool expression?

e.g.
input: 1&&~0&&0||1
output: 1

Did you try just that?

int main()
{
bool answer = 1&&~0&&0||1; // Ta Da!
// that's it.
}

you could be cute and even get this answer printed to your screen at
compile time. (i.e. you don't even have to run the program).

something like:

template<typename A>
class Answer {
private:
Answer(){}
};

int main()
{
const bool answer = 1&&~0&&0||1;
Answer<answer> is;
}

The answer will appear in the error message you receive trying to
compile the program.

No, not in standard C++. You'd have to write a simple parser.
