simple string problem

Ok I am new to C++ and I have this problem:

Code:

---

details = dateStr + "," + staffid + "," + totalitems + "," + totalprice + "," + payment_method + "," + amount_paid + "\n";

---

error C2110: cannot add two pointers

Any help on this? The data strucutres are:

string details;
char dateStr[9];
int staffid;
int totalitems = 0;
double totalprice = 0;
int payment_method;
double amount_paid = 0;

Post a bit more of the code. When you say data structrues, I think of this:

Code:

---

struct Fruit
{
  string lemon;
  int lemonAmount;
};

---

You have a list of varible declarations

try this

Code:

---

#include <string>
#include <sstream>

int main()
{
        std::string details;
        std::stringstream stuff;
        char dateStr[9] = "Hello";
        int staffid = 0;
        int totalitems = 1;
        double totalprice = 0.5;
        int payment_method;
        double amount_paid = 0;
        stuff << dateStr << "," << staffid << "," << totalitems << "," << totalprice << ",";
        details = stuff.str();
}

Thanks a lot, that really helps :)
