[Solved] Reverse the order of an integer in C [closed]
You can just read it in as a string. int main() { char str[80]; fgets(str, 80, stdin); strrev(str); printf(“%s\n”, str); } void strrev(char *str) { char *end, tmp; end = str + strlen(str) – 1; for (; end > str; –end, ++str) { tmp = *end; *end = *str; *str = tmp; } } I … Read more
[Solved] Save a string on a server using JavaScript and PHP
No, using only javascript you can not write files on a server, because your javascript runs on the client side (the browser). You need either Ajax and a server side script (like PHP) to handle the saving, or if you only want to use it with one browser (chat with yourself?), you can store stuff … Read more
[Solved] some simple coding in python, don’t know what to do
The problem is, that your value i is an integer and the print-function takes a string as parameter. Therefore you need to cast your variable using the str() function. Your code should look like this: for i in range(999999999999999): print (“sending messages no.” + str(i)) Now, I encourage people to learn Python and so I … Read more
[Solved] Want to allign image between paragraph
It’s hard to help without some markup, but you can’t float centre, so it would be best to do something like this; <style> .grid-three{ width:33.33%; display:block; float:left; } </style> <p class=”grid-three”>blah blah…</p> <img class=”grid-three” src=”https://stackoverflow.com/questions/35550841/blah” /> <p class=”grid-three”>blah blah…</p> This is a very simple configuration – you may want to experiment to get this working … Read more
[Solved] Varying Bar Width on BarChart panning – Achartengine
I was able to resolve the changing bar width issue by ensuring the serie was a “perfect” suite for x values, changing this : {17, 4, 24, 3, 25, 7, 26, 10, 27, 4} to this : {17, 4, 18, 0, 19, 0, 20, 0, 21, 0, 22, 0, 23, 0, 24, 3, 25, 7, … Read more

[Solved] Unordered List and fonts appearing differently in different browsers
The <details> element is not currently (11th May 2016) supported by IE and is an experimental feature in Firefox requiring a preference ‘flag’ to be set/enabled. Per MDN This feature is available since Firefox 47 behind the preference dom.details_element.enabled, defaulting to false, except on Nightly and Aurora versions (bug 1241750). Support for it is enabled … Read more
[Solved] Why do we need a private constructor at all?
We can’t instantiate more than one object at a time via private constructors. No, we can. A private constructor only avoids instance creation outside the class. Therefore, you are responsible for deciding in which cases a new object should be created. And as expected both the strings are being printed. Did I miss something? You … Read more
[Solved] Iterate through two directories [closed]
I was wondering if there is a better way of achieving this in C# without iterating through each directory and storing the details in a separate list. Use EnumerateFiles on both directories, zip-join them, and then run the join through a foreach loop. var firstFiles = Directory.EnumerateFiles(…); var secondFiles = Directory.EnumerateFiles(…); var joined = firstFiles.Zip(secondFiles, … Read more
[Solved] How can I replicate this method to a method without the parameters?
You can extend the class with one of your classes and then use @Override to create a new version of the method. You would then use your class as if it were the class you extended: It has the same methods and functionality, except for the methods you have overridden. An example could look like … Read more
[Solved] System.ArgumentNullException: Value cannot be null. Parameter name: source [closed]
Seats will be null if you call the method without matching data / query argument. You need to also check that, like so for instance: [HttpPost] public String Indexhome( IEnumerable<Seat> Seats ) { if ((Seats == null) || !Seats.Any(s => s.IsSelected)) { return “you didnt select any seats”; } else { return “you selected ” … Read more
[Solved] Checking amount of booleans that are true, and executing differently depending on the amount [closed]

[Solved] Is it possible to have dictionary where keys are of type bool?
You cannot use a dictionary of Booleans, because it is limited to only two values. This will inevitably lead to key collisions, because you plan to add more than two items to it. Good news is that you do not need a dictionary anyway, because you use it as a collection of tuples. This will … Read more
