    Error that isn't an error

    Hi, I'm new to programming and I'm trying out some basic codes. I'm using Gedit as a text editor and g++ to compile in my CLI. I am learning basic i/o right now so I wrote this little code to try it out.
    Code:
    #include <iostream>
    
    using namespace std;
    
    int main ()
    {
    	int age;
    	int zip;
    
    	age = 20;
    	zip = 50021;
    
    	cout << "I am " << age << " years old." endl;
    	cout << "My zipcode is " << zip << ".";
    
    	return 0;
    }
    I get this error message when I try to compile it:
    Code:
    [metatron@Babylon Desktop]$ g++ -o ioexp ioexp.cpp
    ioexp.cpp: In function ‘int main()’:
    ioexp.cpp:15: error: expected `;' before ‘endl’
    I gather that it's telling me in line 15 I need a ";" before the "endl" command but firstly, I shouldn't need that right? It comes AFTER the "endl." And second, when I did try that I got another error anyway, which I expected.
    Any ideas?

    first:
    Error that isn't an error
    compilers are incredibly "intelligent" pieces of software--they do not lie.

    the line in question does have an error in it:
    Code:
    cout << "I am " << age << " years old." endl;
    you are trying to concatenate " years old." and 'endl'. in order to concatenate, you have to use "<<", as you did with the other strings.

    Thanks, you know, when I came back to it and looked again I figured that too. The problem was that I was using a bit of code in a tutorial as a reference and it was not a complete line of code. Thanks for getting back! I look forward to utilizing this forum as I learn.

    As a side note, this isn't C. You don't have to declare all your variables at the top of your function.
    This:
    Code:
    int age;
    int zip;
    
    age = 20;
    zip = 50021;
    could have just as easily (and probably more clearly) been written as:
    Code:
    int age = 20;
    int zip = 50021;

    Thanks, I was a little mixed up about that so I just wrote it all out to make myself feel better
