    Lightbulb total noob with a problem

    hey im totally new to all this programing stuff but im trying to learn. Im working from a SAMS book on C++ and for one exercise i have to type in the following code:

    Code:
     #include <iostream>
     int main()
     {
       int x = 5;
       int y = 7;
       std::cout << endl;
       std::cout << x + y << " " << x * y;
       std::cout << end;
       return 0;
    }
    I get these error messages using Microsoft Visual C++ 2005

    Code:
    error C2065: 'endl' : undeclared identifier
    
    error C2065: 'end' : undeclared identifier
    any help would be appreciated as i am pretty sure i have typed it all in right! thanks.

    endl is in the std namespace so you need to do
    Code:
    std::endl
    As you've done with cout. End looks like a typo.

    both of them should be std::endl instead

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    or you can just use
    Code:
    using namespace std;
    above your int function and then you wont have to use
    Code:
    std::cout
    just
    Code:
    cout
    .

    It think thats easier to learn.

    because the book, uses
    Code:
    std::cout <<"\n";
    instead of what you typed.
    Code:
    "\n";
    gives you basically the same effect as
    Code:
    endl
    you are still on page 21 of the book, you need to read a bit more of the book and you will find the differences.
