I should be getting a day of the week. 0 should be monday and 6 should be sunday.I don't know if it's run time error or what. I have tried everything that I can think of.  #include &lt;iostream&gt;  using namespace std; string getDayOfWeek(int dayNum){     string dayName;     switch (dayNum){     case 0:         dayName = "Sunday";         break;     case 1:         dayName = "Monday";         break;     case 2:         dayName = "Tuesday";         break;     case 3:         dayName = "Wednesday";         break;     case 4:         dayName = "Thursday";         break;     case 5:         dayName = "Friday";         break;     case 6:         dayName = "Saturday";         break;     default:         dayName = "Invalid Day Number!";     } }  int main() {   cout &lt;&lt; getDayOfWeek(1);     return 0; }
Compiling the following code and got the error of type illegal.  int main() {     // Compilation error - switch expression of type illegal     switch(std::string("raj"))     {     case"sda":     } }   You cannot use string in either switch or case. Why? Is there any solution that works nicely to support logic similar to switch on strings?
I use Gedit a lot and thus tend to have a lot of tabs open at any one time. In Gedit 2.* I could switch between tabs using my mouse wheel but since Oneiric I can't. I assume this is because of various GTK "upgrades".  Does anybody know of a plugin (or workable fix -- that doesn't require me to recompile everything and its brother) that will see me back to mousewheeling my day away? What happened to the “‑est” and “‑eth” verb suffixes in English? What happened to them, and how were they once used? Straining my mind to sound archaic, I came up with the following:     Dost thou thinkest thou can escape thy sins?   and     Bringeth me mine armor and favorite sword.   I’d like to use these suffixes intelligently, so my questions are: how are ‑est and ‑eth properly appellated in conjugations, and  when and why did they disappear? How do you guys go about controlling column padding in tables?   Update  To clarify, I'm looking for a way to control both vertical and horizontal padding. So, if I had a simple table like in the following code snippet, I could pad the columns and make them look a bit less... ugly. :P   \begin{tabular}{|l|l|}     \hline     column 1 &amp; column 2 \\      \hline     I really would like this less &amp; crammed\\     \hline \end{tabular}   I tried this by using the command \vspace but it leaves gaps in the vertical lines. How to change background colour in texworks I am using texworks for the first time, I want to change the background of the editor from dark to white, as the code is not visible in dark background. I am using texworks in Manjaro Linux on GNOME desktop environment. Please help me. Rotate whole animation by 90 degrees I make my animation and now I realized that its pointed in wrong direction I used -y (native blender) as direction but I need to be pointed at x axis so what would be the easiest way to rotate whole animation, to switch -y with x :) Smoothness constraint of wave function Is there anything in the physics that enforces the wave function to be $C^2$? Are weak solutions to the Schroedinger equation physical? I am reading the beginning chapters of Griffiths and he doesn't mention anything. How can I stop applications and services from running? After using gdalwarp to project and align-to-grid (via -tap) a number of rasters I noticed that the output rasters were significantly larger than the original rasters. A fairly thorough web search turned up :  Frank Warmerdam explained the reason: &quot;On careful review, the difference in the file in question is because gdal_translate uses the TIFFWriteScanline() interface to write the output file from within GTiffDataset::CreateCopy?(), and this only writes as much of the final 'strip' of the file as is required to complete image area. But gdalwarp goes through the blockio interface which writes the complete final strip, even the portion that falls off the end of the file.&quot;  This Trac issue is ~7 years old, however, and I know some changes to the GDAL utilities, including gdalwarp have been made since. I'd like to know if the above reasoning still holds and if the file size inflation I'm seeing is &quot;normal.&quot; The word &quot;normal&quot; here might be taken to mean unsurprising or expected but, more importantly: is there anything that can be done to mitigate the effects i.e. reduce the output raster file size? Below is a table of the file size inflation I'm experiencing. Input File Size (bytes)     Output File Size (bytes)    Inflation 1437380431                  1698334217                   18% 1428001178                  1698334433                   19%   41683165                   137036637                  228%  The input TIFF files were created in ArcGIS and thus have external Worldfiles, XML and DBF files but these do not make up the difference in file size. Here is a sample gdalwarp call as I've used it in all of these cases; the actual execution was handled by a Python subprocess (subprocess.Popen): $ gdalwarp -tap -tr 30 30 -t_srs &quot;+proj=aea +lat_1=20 +lat_2=60 +lat_0=40 +lon_0=-96 +x_0=0 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs&quot; -co &quot;COMPRESS=LZW&quot; input_file.tif output_file.tif  I understand that in rare cases compression makes a larger file, but the effect is the same without the LZW compression. The ratios in the table are with LZW compression. How to test hypothesis of no group differences? \pdfendlink ended up in different nesting level than \pdfstartlink Electorate badge rules? I just got the  badge on StackOverflow, which is nice, but I noticed a number of top users aren't yet listed (inluding Jon Skeet and Marc Gravell, who would certainly qualify).  This made me wonder how the badges are retrospectively applied. Is it just that the display is heavily cached and the badge is awarded when the user logs in again or something? When do mobs despawn in Minecraft? I understand monsters only spawn in a 9 x 9 grid of chunks centered on the player, and I assume they stay around while they remain within that distance of you. But do they despawn as soon as you move away from them? Or do they remain? If so what (if anything) causes them to despawn? Are the rules any different for passive mobs?  Will running far away from an area and then coming right back clear it of monsters? What are the system requirements for each flavour of Ubuntu Desktop? I'm thinking about installing Ubuntu Desktop, but I don't know what flavor is the best for my system. What are the minimum and recommended hardware requirements? What kind of CPU? How much memory? Should I have Hardware Acceleration? What flavor should I use?  This is an attempt of a canonical answer. My answers have the &quot;official  requirements&quot;, the recommended are a mix of official sources and opinion based (along with the answer it's told the source). You can comment or edit if you feel that the information is obsolete or incomplete. It is a good rule of thumb that any system capable of running Windows Vista, 7, 8, x86 (Intel) OS X will almost always be a lot faster with any Ubuntu flavor even if they are lower-spec than described below. Add space before and after tabular environment The tabular environment does not add any vertical space before or after it. This looks odd, in my view. What is the "correct" or "best" way to add some space? Also, why is there more space after the tabular environment than before it, as seen in the example below?  \documentclass{article} \begin{document} \noindent Here is a line with some text in it.  \begin{tabular}{*4{l}}     Worg &amp; Worg &amp; Worg &amp; Worg\\     Worg &amp; Worg &amp; Worg &amp; Worg\\ \end{tabular}  \noindent Here is another line with some text in it. \end{document} How to change Power button shutdown action to run a script under systemd How does one change the power button shutdown action under say debian 10 systemd to run a custom script instead of shutting down the system?  Back when this was handled by acpi one could edit the scripts in /etc/acpi.  The only suggestion I have found thus far is to replace various power related binaries with my script.  Is there a way to do this without replacing binaries? How do I add a new, valid tag when I don't have enough reputation? I'd like to post a question on StackOverflow, but I think I should be able to tag it with    . Poor me, there is no  tag; There is  and , I'm certainly not sure this is the right thing to do, so figure I'll start here.  Edit Question located here: Problems with fonts I'm an average user of LaTeX, but not proficiency.

How often did Gandalf return to Hobbiton after the events of The Hobbit? How do you make an image emission without washing out the image? I am trying to make a computer monitor. This means I have to have an image texture for the screen. My image texture is currently connected to an Emission BSDF shader. Unfortunately, when the emission is bright enough to emit light, the image is white-washed. I tried adding a Brightness/contrast node to the image before pushing it into the Emission BSDF, but it seems to directly counter the Emission's strength.
