I'm new in C++, where to start from ?

[Burtin]

Well, I made a little program, but I would like to know couple of things.

Here is my program

#include <iostream.h>
int main()
{
float a, b;
    cout<<"Enter voltage: ";
    cin>>a;
    cout<<"Enter amperage: ";
    cin>>b;
    cout<<"---------------------------------------\n\n";
    cout<<"Power: ";cout<<a*b;cout <<"W";
    system("pause");
    return 0;
}

Well, I want to put this program to repeat, not to terminate it after the first calculation. And how can I enter line breaks, I want to put the message "Press any key to continue" below. P.S - I can't use \n to do this.

Hope you understand
