    Dev-C++

    Hi

    I was wondering if anyone could help me with my program I'm using the newest version of Dev-C++ here is what I typed:

    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;
    }
    and here is the error message I get:

    'endl' undeclared (first use this function)
    'end' undeclared (first use this function)

    if anyone can tell me what to do that would help alot. Thanks in advance

    endl is in the std namespace as well.

    you need
    Code:
    std::cout<<std::endl;

    If you weren't aware of it, you can also eliminate all the std::'s by putting the line
    Code:
    using namespace std;
    after your include directives. There's no technical difference that I'm aware of - it's just a matter of style preference.

    the technical difference is that by doing that you can no longer use any other cout's or endl's in any other namespaces... but having something else with the same name as anything in the standard namespace is very poor programming practice.

    Use a Basic template like this for evrey program you create, then you can eliminate all the
    errors you had example:

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    
    cout << "delete me" << endl;
    
    return 0;
    }

    I would actually recommend not doing that... sure it's easy, but using the using namespace std; line should probably not outlive your early-to-mid learning stages... it'd be better to put
    Code:
    using std::cout;
    using std::endl;
    that way you'll know what exactly comes from the standard library. for examle, I'll bet you'd never know why this code is wrong just by looking at it:
    Code:
    #include<iostream>
    
    int main()
    {
        std::cout<<"Hello World"<<std::endl;
        ifstream file("file.txt");  //open a file
        file.close();  //close the file
        return 0;  //return 0 to the OS
    }

    it should be std::ifstream, right?
    and also <fstream> should be included
