Exercise 1_2 multiple console outputs. I would like to reduce the number of console output statements
Scope

This is really just limited to style and code formatting. 

Two (almost) substantive points


You should get in the habbit of not:


using namespace std;


It can get you into name-clash issues later, as you progress. 


You should be aware that std::endl flushes the stream buffer. This is often unnecessary, unwanted and can be slow if used in a tight loop. You should use '\n' for most situations. If you are worried about
platform specific line-ending, don't be. '\n' adapts, just like
std::endl.


Code formatting


Install clang-format or similar to help you with formatting. 


All I did was to integrate your endl into the strings and hit "auto-clang-format" and I got this:

#include &lt;iostream&gt;

int main() {
  std::cout &lt;&lt; "Hello everybody!\n"
            &lt;&lt; "My name is AK.\n"
            &lt;&lt; "Goodbye.\n"
            &lt;&lt; "\n"

            // Poem
            &lt;&lt; "Twinkle, twinkle, little bat!\n"
            &lt;&lt; "How I wonder what you're at?\n"
            &lt;&lt; "Up above the world you fly,\n"
            &lt;&lt; "Like a tea-tray in the sky.\n";
  return 0;
}



Which is "good enough for me". Clang format is very tunable, and I have it configured to something which works for me, and my team, in 99% of cases. So we don't spend time fighting the formatting of the code. 

The above style with "one streaming operator" &lt;&lt; at the beginning of each line is what we use most of the time. It makes sense when you have literals interspersed with variables and/or function calls. 

For this very specific (and rather atypical?) case, you could, as someone else pointed out, also just stream it all as one continuous literal. C++ allows you stop/start string literals like this:

#include &lt;iostream&gt;

int main() {
  std::cout &lt;&lt; "Hello everybody!\n"
               "My name is AK.\n"
               "Goodbye.\n"
               "\n"

               // Poem
               "Twinkle, twinkle, little bat!\n"
               "How I wonder what you're at?\n"
               "Up above the world you fly,\n"
               "Like a tea-tray in the sky.\n";
  return 0;
}



Hope that helps.
