Hi Jes, Something helpful that folks do in industry (not so much in academia from my experience though) is called a code review where people insert specific comments on selected lines of code. 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!
