Im a noob with an easy question

I have a program which is small and easy the code is

Code:

---

#include<iostream>
using namespace std;

int main (void)
{       

        double dnumber1=0.0;
        double dnumber2=0.0;
        double dnumber3=0.0;
        double daverage=0.0;
       
        cout << "Please Enter 3 Numbers " <<endl;
        cin >> dnumber1;
        cin >> dnumber2;
        cin >> dnumber3;
       
        daverage = (dnumber1 + dnumber2 + dnumber3) / 3;
       
        cout << "The Average Of The Numbers Is: " <<daverage <<endl; <<endl; //Problem is in this line
       
        system("pause");
        return 0;

}

---

that is a short easy program but I get the error saying
"19 expected primary-expression before '<<' token "

I am using Devc++ the newest beta version

Code tags on the first post! Very nice.

<<endl; <<endl;

Remove the red part.

Thanks for recognizing my code tags Its whats used everywhere on any forum

why does the other endl; have to be taken off doesn't that just make an extra line

The problem is that there is a terminating semi-colon sandwiched right there. If you want that second endl, then you should write:

Code:

---

cout << "The Average Of The Numbers Is: " << daverage << endl << endl;

---

A new line is just endl, not endl;.
And every line (except for control statements) must end with a ;.

endl is just a variable/constant at all.

so putting a statement like

Code:

---

endl;

---

or

Code:

---

dnumber1;

---

Means nothing but error.

Like codeplug said, it's this part:

Code:

---

<<endl; <<endl;

---

.

Basically, you only use the ';' after each line, not between functions on the same line :). Take off the first ';'.

Code:

---

<<endl << endl;

---

will work :).

Good luck!
Thanks.

Actually, std::endl is a function (template).

Thanks alot for your help I now understand

Great! No Problem :).

It does take quite a while to get used to, but once you're used to it, you'll be doing it automatically (like me ;)).
Also, I would recommend commenting your code. You don't really need to in a simple script like this one, but it's just a starting point so you can get used to it :).

Happy new year!
