C++ setprecision

Question

newbie learning C++ and not understanding the problem I have trying to use setprecision(2) says setprecision(2) is undefined. If anyone could help I'd be most grateful.

 #include <iostream>     
 #include <string>
using namespace std;

int main() 
{
double price,shipping;

cout<<"Enter total price of of the order: "<<endl;
cin>>price;

if(price > 75) 
    shipping = 0;
else if(price > 50) 
    shipping = 5;
else if(price > 25)
    shipping = 10;
else if(price > 0)
    shipping = 15;

cout<<"Total price of order including shipping is: "<<fixed<<setprecision(2)
    <<price + shipping<<endl;





return 0;
system("pause");
}

Learn to love the documentation. Open documentation for `std::setprecision` and read it. Also, stop `using namespace std;`. — SergeyA, Jun 14 '16 at 20:42

I have to use using namespace std; as I am using virtual studio. — Sam777, Jun 14 '16 at 20:47
He's suggesting you prefix your std namespace tokens with std:: rather than using "using namespace std." For example, std::cout, std::cin, etc. You can remove the "using namespace std" if you do that.

setprecision() function is included in the iomanip library. Simply include that library into your program. and you should be fine. :)

#include<iomanip>
