compiler errors - Problem compiling simple C++ progam -


I found this simple C ++ [I think] the program was provided to check the maximum size int Which can be archived: 

  #include & lt; Limits.h & gt; # Include & lt; Iostream & gt; Zero main (int argc, char * argv []) {cout & lt; & Lt; "INT_MAX" & lt; & Lt; INT_MAX & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX +1 =" & lt; & Lt; INT_MAX + 1 & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX -1 =" & lt; & Lt; INT_MAX - 1 & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX / INT_MAX" & lt; & Lt; INT_MAX / INT_MAX & lt; & Lt; Andal; Cout & lt; & Lt; "(INT_MAX +1) / INT_MAX" & lt; & Lt; (INT_MAX +1) / INT_MAX & lt; & Lt; Endl; Cout & lt; & Lt; "(INT_MAX -1) / INT_MAX" & lt; & Lt; (INT_MAX-1) / INT_MAX & lt; & Lt; Endl; Cout & lt; & Lt; "INT_MAX / (INT_MAX +1)" & lt; & Lt; INT_MAX / (INT_MAX + 1) & lt; & Lt; Endl; Cout & lt; & Lt; "INT_MAX / (INT_MAX -1)" & lt; & Lt; INT_MAX / (INT_MAX-1) & lt; & Lt; Endl; }

I am trying to compile: 

  gcc -o int_max int_max.cpp

but I get the following error: 

  int_max.cpp: 4: error: ':: main' should return 'int' int_max.cpp: 'int main (int, char * *) ': Int_max.cpp: 8: Error:' cout 'has not been declared in this area int_max.cpp: 8: Error:' endless' in this area has not been declared int_max.cpp: 9: Warning: Expression int_max Overlaw integer in .cpp: 13: Warning: expression in integer o Vertflow int_max.cpp: 15: Warning: Integer multiplication in expression

I tried to add return 0 at the end of the main, but he did not help. Any ideas I have done wrong?

It's possible that this is actually a snippet, but I think the lecturer was saying C ++.

Cheers

file with .c In the GCC are compiling the C ++ code> Extensions? 

  // Use the new C ++ header file instead of their .h version. #include & lt; Climits & gt; # Include & lt; Iostream & gt; // cout and endl are declared in std namespace. using namespace std; Int main (int argc, char * argv []) {cout & lt; & Lt; "INT_MAX" & lt; & Lt; INT_MAX & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX +1 =" & lt; & Lt; INT_MAX + 1 & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX -1 =" & lt; & Lt; INT_MAX - 1 & lt; & Lt; Andal; Cout & lt; & Lt; "INT_MAX / INT_MAX" & lt; & Lt; INT_MAX / INT_MAX & lt; & Lt; Andal; Cout & lt; & Lt; "(INT_MAX +1) / INT_MAX" & lt; & Lt; (INT_MAX +1) / INT_MAX & lt; & Lt; Endl; Cout & lt; & Lt; "(INT_MAX -1) / INT_MAX" & lt; & Lt; (INT_MAX-1) / INT_MAX & lt; & Lt; Endl; Cout & lt; & Lt; "INT_MAX / (INT_MAX +1)" & lt; & Lt; INT_MAX / (INT_MAX + 1) & lt; & Lt; Endl; Cout & lt; & Lt; "INT_MAX / (INT_MAX -1)" & lt; & Lt; INT_MAX / (INT_MAX-1) & lt; & Lt; Endl; Return 0; }

and use g ++ to compile.

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...
