Question

I have been working in Java since I started programming and decided to learn c++.
What I wrote in Java looked like this:

showMessage("Hello world" + randomNumber);

And it showed text + integer or float or whatever. But it wont work in c++.
Error message by xCode: Invalid operands to binary expression ('const char *' and 'float')

Cheers!

You can do a sprintf according to Anton, or to be more c++:

std::stringstream ss;
ss << "Hello, world " << randomNumber;
showmessage(ss.str());

(there’s nothing wrong with sprintf, especially if you use snprintf instead).
