Translation mistake. No more rounding needed.

And could you stop writing these comments please? If somebody doesn't know something, (s)he checks the documentation / searches for the answer on the internet / asks for help / get the answer from correct logical assumptions at the very least, but you're not even trying.

No, that's how you initialize an empty string. Do something with it inside your loop now.

there needs to be something in the "", right?
also, thanks for all thee help you've given me

Avoiding it won't help for sure ;)

i should read about the string library first, right?

std::string count = ""; and try figuring out the rest ;)

You have the same problem you had in the other kata, why don't you try using a string instead of an array of chars?

.

Try the first results of googling c++ std::string.

I am using c++ and I don't get how to make the answer round to the nearest decimal.

where do I read up on the std::string library?

You're not null terminating the char[] properly, so your answer includes trailing garbage. Either initialize the whole array to null chars, insert a null char at the correct index, or (best option) replace the char[] with a std::string and read up on the methods for that class. As FArekkusu said, you're tackling this like a C coder rather than a C++ coder. :-)

Just write it in C++, because this is C code.
