There is unlikely to be an objective answer to this, as both the K&R and 1TBS styles emerged in the context of the C programming language, where there were no class definitions. Since derivative languages of C that support classes (e.g., C++, Java, etc.) share most of the syntax, it is only natural that the … Read more
The above code can be rewritten as: indices = [] for n, value in enumerate(self.BUSES[i]): if value==1: indices.append(n) enumerate returns a pair of (index, value at that index) for a given list. So you are testing if value at a given index is 1, and if that is true, you add the index to indices. … Read more
At the top of your Visual Studio, you should see the build configurations dropdown. Set that to “Release”. Go to the properties of your project. Note, project, not solution. If you have multiple, this should be the one set as startup project. In the properties, go to the “Build” tab. Scroll down a little and … Read more
if expressions have to be boolean. Say I have a string: string test = null; if (test) won’t compile because test is not a bool. It just returns the string reference. So, to check for null, you actually have to check for null: if (test != null) is an expression that does return a bool, … Read more
This website has a calculator: It is the number of seconds since January 1st, 1970 at midnight GMT. The 11, is because something took 11 seconds. Here’s a post explaining why 1970 was chosen along with the definition: Unix time, or POSIX time, is a system for describing points in time, defined as the number … Read more
Sequential logic is faster (see the benchmark below the fold), but it almost never matters. The clearer and more maintainable code should always be selected. Only a demonstrated need should cause one to cease optimizing for the programmer and begin optimizing for the machine. By demonstrated, I mean measured–you ran it and found it to … Read more
Seeing as this is a course header, I think students are supposed to include it and then use most of the standard library that way. I am surprised Stroustrup teaches it that way (it is, in my opinion, still bad practice), but it does mean that he has one less bit of syntax to explain … Read more
print() returns None in Python 3. So, you’re trying to concatenate(or add) None with msg, which results in an error. Try string formatting: print (“Message from server : {}”.format(msg)) 3 solved Python 3.3 socket programming error [closed]
The problem is in your CSS, specifically these 3 attributes: @media (max-width: 991px) .sidebar { top: 0; max-width: 80%; position: fixed; } Position:fixed and top:0 means your sidebar is forced to stick to the top of the page element, where on a mobile-view, you want the sidebar to stack above or below the content. Changing … Read more
You are correct: !a giver you 0 and 0 == b is 0, So, c = ++b gives b = 4 and c = 4. The a is not changed. solved What is the output? C Programming [closed]
