First Coding Interview

I was given a to reverse a given string. It was easy.

void reverse(char* begin, char* end)
{
// to do function
}

void reverseString(std::string str)
{
reverse(str.data(), str.data() + str.size());
}

int main()
{
std::string str = "Reverse" // "esreveR"
std::cout << reverseString(str) << std::endl;

reverseString(" "); // " "
reverseString("I Love You") // "I evoL uoY"
}

Thanks.
