c++ - linking <iostream.h> in linux using gcc -


I'm trying to run my first C ++ program in Linux (linux mint 8). I use both GCC or G ++ with the same problem: the compiler is not able to find the library, which I am trying to import.

I have some doubts as if I should copy the iostream.h file in the work folder (which I do not know), move my file somewhere else to compile or use some option Sort Sort

Thank you for your suggestions.

Here is the GCC command, the C ++ code and the error message: 

  GCC -o addition list2 .5.c

. 

  #include & lt; Iostream.h & gt; Int edition (int a, int b) {return (a + b); } Int main () {cout & lt; & Lt; "Results:" & lt; & Lt; Addition (2, 4) & lt; & Lt; "\ N"; Return 0; }

. 

  listing2.5.c: 1: 22: error: iostream.h: No such file or directory is listed.2. Cc: Function in 'Main': listing2.5.c: 10: Error: 'Cout' undeclared (first use in this function) listing.2.5.c: 10: Error: (Each unauthorized identifier is reported only once in the list : 10: Error: appears for each function in it.)

The code is now compiled, but I can not run it using the command line through the filename. addition: command not found any suggestions?

  • cout is defined in std :: namespace , You just need to use cout instead of std :: cout .
  • If you want to use G ++ to compile C ++ programs, it will link to standard C ++.
    • library. GCC will not have GCC will also compile your code as C code if you have it one. C suffix. Give your files the .cpp suffix.

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...
