c++ - Storing values in arrays -

-

the user supposed enter name followed grades. when user hits -1 there can no more grades stored individual. when user types x, s/he enters total , -1 indicate no more grades can stored. don't understand why loops outputting in weird way. names array storing int values supposed go numbers array.

for example, input should this:

jane 3 4 -1 lane 4 5 -1 x   10 10 -1

the output should this:

jane 3 4  jane had 7/20 lane 4 5 lane had 9/20

this work far:

#include <iostream> #include <cstring> #include <string>  using namespace std;  int main() {  string name = " ";  string names[20];  int numbers[20];  int = 0, j=0, number;    {    cin >> name;    names[i]=name;    i++;     j=0;    if(number!=-1)    {        cin>> number;        numbers[j]=number;        j++;    }  }while(name!="x");   for(int x = 0; x <= i; x++)  {   for(int y = 0; y <= j; y++)   {       cout << names[x];   }  }  }

one issue code ,

 int = 0, j=0, number;

you use uninitialised number in code

if(number!=-1)

this contains garbage values can co-incidentally -1

c# - must be a non-abstract type with a public parameterless constructor in redis -

-
when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

c# - ReportViewer control - axd url -

-
i've embedded microsoft.reporting.webforms.reportviewer control in aspx. site works on mysite.com. when try exmple export report, there new black window opened address mysite.com/reserved.reportviewerwebcontrol.axd... it's working fine. but.. pass axd via proxy. mean, i'd force export use url myproxy.mysite.com/reserved.reportviewerwebcontrol.axd... redirect request mysite.com/reserved.reportviewerwebcontrol.axd... i've noticed, link build within js (that inlcuded in axd): exportreport: function(format) { if (this.exporturlbase == null) return false; window.open(this.exporturlbase + encodeuricomponent(format), "_blank"); return true; }, the url axd stored in exporturlbase . how can change proxy serwer url? it possible modify exporturlbase field in javascript. report stored in placeholder somewhere on page, once found can create call _getinternalviewer() function on gain access exporturlbase. have @ following code: ...

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
