And if you aren't passing command line arguments or the programme has no use for them then those arguments aren't required.

Hi,The added code is done from VS (I remember having that problem and fixed it by creating a general CPP project).Cheers, Joseph -----Original Message-----From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Alex MidenceSent: Tuesday, July 06, 2010 8:25 AM To: programmingblind@xxxxxxxxxxxxx Subject: Re: What's wrong with my code? Hi, all, This looks like something I'm working on too. I've a question though: Why do books tell you to write: int main() but, I've seen folks here and on some websites I've looked at write: Int main (int argc; char; **) or something like that?

I'll go ahead and do that below prefixing my comments with "dave:". Ken and Joseph had some great comments as well. //Ch5 Exercise 4, page 287 //Calculates and displays the average of three test scores dave: "//" only need one per line. You only need to put another "//" if you start a new line (it doesn't matter how many sentences you have in a comment as long as they're still on the same line.) //created/revised by Jes Smith on July 5 2010 #include <iostream> using <<std::cout;>> using <<std::cin;>> using <<std::endl;>> dave: "using" has the purpose of restricting namespaces such as "using namespace std;". This has the effect of letting you say cout << "hello!" as opposed to std::cout << "hello!" It's a good topic to read up on in a C++ book. //declare variables int score_1 (0); int score_2 (0); int score_3 (0); dave: these are declared with global scope; you may want to consider putting them in the main routine below. Also, simple types like int or float can be assigned to (such as int a = 0;). //begin program int main() {cout< "Please enter your first test score. You may enter decimal values: ";dave: the "<>" syntax can be tricky here. the "<<" operator directs the string on the right to the stream on the left. It should be written as cout << "hello!"; cin << score_1 >>; cin <<score_2 >> ; cin <<score_3 >> ; dave: Think of cin as an in-coming stream which you want to direct elsewhere. The "cin" blob is just a user typing stuff and you want to direct it to a variable. To do this, you can write cin >> some_var; The cin object only "writes" to the variable when the user presses enter. return 0 } Hth!

Any assistance would be appreciated, as well as any feedback on how I am doing writing the code. I have this habit of not writing the code all the way through, and compiling the program bit by bit to make sure I don't get any errors in the process of coding. I just want to make sure that the code I have already written is working as it should before I continue writing. I'm sure this is not a good habit to get into. Thanks for any help.
