C-String problem

[2kaud]

woah, thanks for all the info. I don't know some of the code both of you posted, but I'll figure it out. I haven't learned much yet, hence, the horrible code I made.

How are you learning c++? You may like to look at these sites for more info

I have a book called C++ Early Objects. I'll look into those links as well though, thank you.

Is that book the one by Gaddis, Walters & Muganda?

Yes

void  lastChar(char const* str)
{
char const *const last = strchr(str, '\0');

	(last > str) ? std::cout << *(last - 1) : std::cout << "null";
}

In addition to laserlight's post #10, I don't see any advantage in using the ternary operator here instead of a plain if-else. The result of the operation is discarded anyway.

Guilty as charged In mitigation I was trying to identify a polymorphism bug at the time and I originally wrote

//Don't try this at home
std::cout << (last > str) ? *(last - 1) : "null";

but this doesn't compile of course! (incompatible operand types) So I just quickly changed it to

(last > str) ? std::cout << *(last - 1) : std::cout << "null";

//Don't try this at home
std::cout << (last > str) ? *(last - 1) : "null";

In fact I considered suggesting that very variation to make the ternary operator at least half-way useful here, but came to the conclusion that it wouldn't compile before finishing my post.
