C# user input to set size of array and loop array to display elements -


the goal create array size user input via how many test scores. create loop populate array prompting user each test score 0 100. display results, typically using loop.

question: why when test scores entered example "50" adds 50 elements of 0 array?

any assistance grateful, thank you. i've seen few similar posts couldn't resolve issue. also, 1 in spanish. 

using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks; using static system.console;  namespace consoleapp3 {     class program     {         static void main(string[] args)         {                   // prompt user ask how many test scores build size of array                   write("how many test scores total: ");                 string ssize = readline();                           int = convert.toint32(ssize);                               int[] score = new int[i];                // create loop of asking test scores limited array ssize              (int = 1; < + 1; a++)             {                  write("please enter test score " + + " 0 100: ");                 string testarray = readline();                   int g = convert.toint32(testarray);                  int[] tests = new int[g];                  //create loop display test scores                 foreach (var item in tests)                     console.writeline(item);                      }              }         } }

because create new array inside of loop size of "score" user entered , loop on it. values 0 because when create array populated default value of type, in case 0. second loop should after first 1 , shouldn't creating arrays inside of first loop, populating original array (score) created begin with.

here's want. note should index starting @ 0 , not 1.

write("how many test scores total: "); string ssize = readline();           int = convert.toint32(ssize);               int[] score = new int[i];  // create loop of asking test scores limited array ssize (int = 0; < i; a++) {     write("please enter test score " + (a + 1) + " 0 100: ");     string testarray = readline();     int g = convert.toint32(testarray);     score[a] = g; }  //create loop display test scores foreach (var item in score)     console.writeline(item);

you may want consider using int.tryparse can determine if user enters invalid value.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
