Multiple word input in string in c -


while writing c program wrote following code can put more 1 word each string ' 

#include<stdio.h>  struct address {   char house[20],street[20],city[10];        }; struct student {   struct address a; }; struct student getdata(); struct student getdata() {   struct student s;   printf("\n\nenter data\n\n");   printf("house  : ");   if(fgets(s.a.house,20,stdin));       printf("street : ");   if(fgets(s.a.street,20,stdin));   printf("city   : ");   if(fgets(s.a.city,10,stdin));   return s; }  int main() {   struct student s;   int i;   printf("\nenter number\n");   scanf("%d",&i);   s=getdata();   }

but in terminal got

    house  : street :

that unable feed data house instead takes me directly towards street.

after calling scanf, there newline left in input buffer. when fgets later called, reads buffered newline , returns immediately.

to clear input buffer after scanf, call getchar read characters until read newline.

scanf("%d",&i); while (getchar() != '\n'); s=getdata();

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 ...
