Return a string function

[Sandz]

Hi, I need help to understand more about a function which uses a string. eg.
string getprice(double& double) where the 2 arguments are initial price and number of bidding.

How do I return a string to the function? Please guide me thank you.

If you don't know what your own function is supposed to do, how could we ?

Maybe the function should compute the total price and write its value into a human readable format for later display ?

It returns the name of the final bidder.

How do I return a string from a function? By making std::string as its result type.

#include <string>

std::string function_returning_a_string()
{
    std::string str = "whatever" ;
    // ...
    return str ;
}
