I am having difficulty understanding how this situation will work.

using std::string;

//Prototypes
string MixCase(string& sString);
void UseRef (string& sRefString);
void UseCopy(string sCopyString);

void main(int argc, char** argv)
{
string MyString;

UseRef (MixCase(MyString));
UseCopy(MixCase(MyString));
}

string MixCase(string& sString)
{
string sTempString;

...

return sTempString;
}

string UseRef(string& sRefString)
{
//Will sRefString be valid when it comes from MixCase ???
}

string UseCopy(string sCopyString)
{
//This should work just fine
}

I am trying to convert Delphi (pascal) code to C++. The Delphi code that I am converting does this type of stuff all the time.

Any comments are welcome.

Thanks in advance.
