c++ - Why can't I use float value as a template parameter? -


When I try to use float as a template parameter, the compiler This code cries, while int works fine.

Is this because I can not use the float as a template parameter? 

  # include & lt; Iostream & gt; using namespace std; Template & lt; Class t, t default value & gt; Class Generic Class {Private: T-value; Public: Generic Class () {value = defaultValue; } T Returnal () {return value; }}; Int main () {GenericClass & lt; Int, 10 & gt; GcInteger; Generic Class & lt; Float, 4.6F & gt; GcFlaot; Cout & lt; & Lt; "The sum of integers \" is & lt; & Lt; GcInteger.returnVal (); Cout & lt; & Lt; "The sum of \ float \" is & lt; & Lt; GcFlaot.returnVal (); Return 0; }

Error: 

  main.cpp: function in `int main () ': Main.cpp: 25: Error:' float 'is not a valid type for a template static parameter main.cpp: 25: Error:'; 'Token key.cpp: 28: Error: request for member' returnee 'in `GCFLat', which is non-class type` int '

I "data structure ", author for game programmers by Ron Penton passes a float , but when I try it does not compile.

< "post-text" itemprop = "text">

existing C ++ standard to use the template as non- float (i.e., the actual number) or the character string does not allow the literal-type parameter you can definitely type float and four * type generic arguments Can use as

Perhaps the author is using a compiler that does not follow the current standard?

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
