Code:

// stringstreams
#include <iostream>
#include <string>
#include <sstream>
using namespace std;

int main ()
{
 string mystr;
 float price=0;
 int quantity=0;

 cout << "Enter price: ";
 getline (cin,mystr);
 stringstream(mystr) >> price;
 cout << "Enter quantity: ";
 getline (cin,mystr);
 stringstream(mystr) >> quantity;
 cout << "Total price: " << price*quantity << endl;
 return 0;
}

i have done this, i open it then there stand enter price: (fill in) then enter then enter quantity: (fill in again) then i push enter but the screen dissapears but the total price must appear :S how can i fix this?

and btw

Code:

// my first c++ program

#include <iostream>
using namespace std;

int main ()
{
  cout << "Hello World!" ;
  cout << "what the fuck!" ;
  return 0;
}

if i start this only a black screen appears for less than a second how can i fix this?

already thx for helping me

Code:

system("PAUSE");

Try placing that before your' ending curly brace ( } ).

for the second part, the end should be

cin.get ();
}
or something like that

Same as system pause, both require user keypress to end the program. But you can use that i guess.

This may even be better done without stringstreams and getline. Here let me show you.

Code:

#include <iostream>

void main(void)
{
 float fPrice=0;
 int nQuantity=0;

 cout << "Enter price: ";
 cin >> fPrice;
 cout << "\nEnter quantity: ";
 cin >> nQuantity;
 cout << "\nTotal price: " << fPrice*nQuantity << "\n";
 system("PAUSE");
}
