I tried to compile this:

Code:
#include "stdafx.h"
#include <iostream>

void main()
{
   //define variables
   float num1;
   float num2;
   float total;

   //Enter data for the variables
   cout << "Enter a value for the first variable;  ";
   cin >> num1;
   cout << "Enter a value for the second variable;  ";
   cin << num2;

   //Add the two numbers together
   total = num1 + num2;

   //Display the result
   cout << "The sum of the numbers = " << total << endl;

}


Got these errors:

Code:
1>c:\documents and settings\shotta\my documents\visual studio 2005\projects\calculator\calculator\calculator.cpp(13) : error C2065: 'cout' : undeclared identifier
1>c:\documents and settings\shotta\my documents\visual studio 2005\projects\calculator\calculator\calculator.cpp(14) : error C2065: 'cin' : undeclared identifier
1>c:\documents and settings\shotta\my documents\visual studio 2005\projects\calculator\calculator\calculator.cpp(22) : error C2065: 'endl' : undeclared identifier


I guess cin and cout and endl are old identifiers, but what are the new one? Because it should be a calculator. I made this with the video tutorial somewhere in the forum

You didn't include the namespace. If you don't use the namespace then you need to add std:: infront of cout, cin, and endl.

Code:
using namespace std;

or
Code:

std::cout
std::cin
std::endl
