I just want to know how to write a c++ function that accepts a string as parameter and return a string back to the main() function.

string foo1( string str )

At this moment in time I want to convert a lowercase Surname to uppercase using a C++ function.

std::string conv_str_to_upper (std::string const& str)
{
   std::string upper;
   // Tell upper how long it's going to end up being, so we can allocate that space all at once
   upper.reserve(str.length());
   // Copy s to upper, but upper-case each character as we go.
   std::transform(s.begin(), s.end(), std::back_inserter(upper), (int (*)(int))&std::toupper);
