The documentation does mention an important drawback to `/bigobj`:

&gt; Linkers that shipped prior to Visual C++ 2005 cannot read .obj files
&gt; that were produced with `/bigobj`.

So, setting this option by default would restrict the number of linkers that can consume the resulting object files. Better to activate it on a need-to basis.


&gt; why is not that flag set by default? There must be a penalty of using that flag, otherwise it would be set by default.

My quick informal experiment shows .obj files to be about 2% larger with `/bigobj` than without. So it&#39;s a small penalty but it&#39;s not zero.

Someone submitted a feature request to make `/bigobj` the default; see https://developercommunity.visualstudio.com/t/Enable-bigobj-by-default/1031214.

    type(A)
    &lt;class &#39;scipy.sparse.csc.csc_matrix&#39;&gt;
    A.shape
    (8529, 60877)
    print A[0,:]
      (0, 25)	1.0
      (0, 7422)	1.0
      (0, 26062)	1.0
      (0, 31804)	1.0
      (0, 41602)	1.0

      (0, 54376)	1.0
    print A[:,0]
      #nothing returned

Now what I don&#39;t understand is that `A[1,:]` should select elements from the 2nd row, yet I get elements from the 1st row via `print A[1,:]`. Also, `print A[:,0]` should return the first column but I get nothing printed. Why?

I&#39;m pretty new to the language. Let&#39;s say I have a string from an HTTP request, such as

    char * request = &quot;GET /favicon.ico HTTP/1.1&quot;;

And I specifically want to know if `favicon` is in that request, perhaps with a boolean value. What is a relatively simple way to go about this? I know how to do it in Java, but I&#39;m more lost with C.

Thanks!

Simple way to check if a string contains another string in C?

The basic Google search [bigobj issue](https://www.google.com/search?q=bigobj+issue) shows that a lot of people are experiencing the [Fatal Error C1128](http://msdn.microsoft.com/en-us/library/8578y171.aspx): &quot;*number of sections exceeded object file format limit : compile with /bigobj*&quot;. The error has more chance to occur if one heavily uses a library of C++ templates, like [Boost libraries](http://www.boost.org) or [CGAL libraries](http://www.cgal.org/).

That error is strange, because it gives the solution to itself: set the [compiler flag `/bigobj`](http://msdn.microsoft.com/en-us/library/ms173499.aspx)!

So here is my question: why is not that flag set by default? There must be a penalty of using that flag, otherwise it would be set by default. That penalty is not documented in MSDN. Does anybody have a clue?

I ask the question because I wonder if the configuration system of [CGAL](http://www.cgal.org) should not set `/bigobj` by default.

I was just going through some code on the Internet and found this:

    float * (*(*foo())[SIZE][SIZE])()

How do I read this declaration? Is there a specific set of rules for reading such complex declarations?


Complex C declaration

    struct A {};
    
    struct B : A {};
    
    int main()
    {
        A* a = new B();
        
        B* b = dynamic_cast&lt;B*&gt;(a);
    }

gives:

&gt; [cannot dynamic_cast &#39;a&#39; (of type &#39;struct A*&#39;) to type &#39;struct B*&#39; (source type is not polymorphic)](https://ideone.com/wxHBB3)

How can I make `A` polymorphic?  I want to safely cast it to B.

(One way is to add a dummy virtual function, but is there a better way?)

I&#39;m beginner to C++ and I&#39;m doing one of the exercises about abstract class and inheritance.

This is my abstract class:

    #ifndef   SHAPE_H 
    #define  SHAPE_H
    class Shape
    {
    	public:
    	    virtual void area();
    		virtual void perimeter();
    		virtual void volume();
    };
    #endif

This is my concrete class that implements the abstract class:

    #include &lt;iostream&gt;
    #include &lt;cmath&gt;
    #include &quot;Shape.h&quot;
    using namespace std;
    
    class Circle : public Shape
    {
		public:
			Circle(int);
		private:
			int r;
    };
    
    Circle::Circle(int rad)
    {
    	r = rad;
    }
    
    void Circle::area()
    {
    	cout &lt;&lt; &quot;Area of this cirle = &quot; &lt;&lt; 3.14 * pow(r, 2) &lt;&lt; endl;
    }
    
    void Circle::perimeter()
    {
    	cout &lt;&lt; &quot;Perimeter of this cirle = &quot; &lt;&lt; 2 * 3.14 * r &lt;&lt; endl;
    }
    
    void Circle::volume()
    {
    	cout &lt;&lt; &quot;Volume is not defined for circle.&quot; &lt;&lt; endl;
    }


I got red lines under `area()`, `perimeter()`, and `volume()` in my `Circle` class, which showed `&quot;Error: inherited member is not allowed&quot;`. I went through my class ppt and googled for answer but no luck. Any help is appreciated.

Why is inherited member not allowed?

This is a bit of a two part question, all about the atomicity of `std::shared_ptr`:

**1.**
As far as I can tell, `std::shared_ptr` is the only smart pointer in `&lt;memory&gt;` that&#39;s atomic. I&#39;m wondering if there is a non-atomic version of `std::shared_ptr` available (I can&#39;t see anything in `&lt;memory&gt;`, so I&#39;m also open to suggestions outside of the standard, like those in Boost). I know `boost::shared_ptr` is also atomic (if `BOOST_SP_DISABLE_THREADS` isn&#39;t defined), but maybe there&#39;s another alternative? I&#39;m looking for something that has the same semantics as `std::shared_ptr`, but without the atomicity.

**2.** I understand why `std::shared_ptr` is atomic; it&#39;s kinda nice. However, it&#39;s not nice for every situation, and C++ has historically had the mantra of &quot;only pay for what you use.&quot; If I&#39;m not using multiple threads, or if I am using multiple threads but am not sharing pointer ownership across threads, an atomic smart pointer is overkill. My second question is *why wasn&#39;t a non-atomic version of `std::shared_ptr` provided in C++11*? (assuming there is a *why*) (if the answer is simply &quot;a non-atomic version was simply never considered&quot; or &quot;no one ever asked for a non-atomic version&quot; that&#39;s fine!).

With question #2, I&#39;m wondering if someone ever proposed a non-atomic version of `shared_ptr` (either to Boost or the standards committee) (not to replace the atomic version of `shared_ptr`, but to coexist with it) and it was shot down for a specific reason.

Is there a non-atomic equivalent of std::shared_ptr? And why isn&#39;t there one in &lt;memory&gt;?

Lately I&#39;ve been asked to write a function that reads the binary file into the `std::vector&lt;BYTE&gt;` where `BYTE` is an `unsigned char`. Quite quickly I came with something like this:

    #include &lt;fstream&gt;
    #include &lt;vector&gt;
    typedef unsigned char BYTE;

    std::vector&lt;BYTE&gt; readFile(const char* filename)
    {
        // open the file:
        std::streampos fileSize;
        std::ifstream file(filename, std::ios::binary);

        // get its size:
        file.seekg(0, std::ios::end);
        fileSize = file.tellg();
        file.seekg(0, std::ios::beg);

        // read the data:
        std::vector&lt;BYTE&gt; fileData(fileSize);
        file.read((char*) &amp;fileData[0], fileSize);
        return fileData;
    }

which seems to be unnecessarily complicated and the explicit cast to `char*` that I was forced to use while calling `file.read` doesn&#39;t make me feel any better about it.  

---
Another option is to use [`std::istreambuf_iterator`](http://www.cplusplus.com/reference/iterator/istreambuf_iterator/):

    std::vector&lt;BYTE&gt; readFile(const char* filename)
    {
        // open the file:
        std::ifstream file(filename, std::ios::binary);

        // read the data:
        return std::vector&lt;BYTE&gt;((std::istreambuf_iterator&lt;char&gt;(file)),
                                  std::istreambuf_iterator&lt;char&gt;());
    }

which is pretty simple and short, but still I have to use the `std::istreambuf_iterator&lt;char&gt;` even when I&#39;m reading into `std::vector&lt;unsigned char&gt;`.

---
The last option that seems to be perfectly straightforward is to use [`std::basic_ifstream&lt;BYTE&gt;`](http://en.cppreference.com/w/cpp/io/basic_ifstream), which kinda expresses it explicitly that *&quot;I want an input file stream and I want to use it to read `BYTE`s&quot;*:

    std::vector&lt;BYTE&gt; readFile(const char* filename)
    {
        // open the file:
        std::basic_ifstream&lt;BYTE&gt; file(filename, std::ios::binary);

        // read the data:
        return std::vector&lt;BYTE&gt;((std::istreambuf_iterator&lt;BYTE&gt;(file)),
                                  std::istreambuf_iterator&lt;BYTE&gt;());
    }

but I&#39;m not sure whether [`basic_ifstream`](http://en.cppreference.com/w/cpp/io/basic_ifstream) is an appropriate choice in this case.

*What is the best way of reading a binary file into the `vector`?* I&#39;d also like to know what&#39;s happening *&quot;behind the scene&quot;* and what are the possible problems I might encounter (apart from stream not being opened properly which might be avoided by simple [`is_open`](http://www.cplusplus.com/reference/fstream/ifstream/is_open/) check).

Is there any good reason why one would prefer to use [`std::istreambuf_iterator`](http://www.cplusplus.com/reference/iterator/istreambuf_iterator/) here?  
(the only advantage that I can see is simplicity)

I&#39;m collaborating with some fellow students to build a python app, and was hoping to use the &#39;training wheels&#39; of Visual Studio intelli-sense. They use python on mac and linux, so ideally our source control repo would consist of just `*.py` source files that we wrote, and a `requirements.txt` export of pip dependancies (using the `pip freeze` method).

I would love to be able to create a new Visual Studio project, then be able to run the following commands (for instance) within that project:

    pip install boto
    pip install fabric
    pip install cuisine
    pip freeze &gt; requirements.txt

And after that, be able to write some code that references these libraries and be able to run it from within Visual Studio.

Is there any way to do this?  Is Python within Visual Studio even able to handle modules in the format they are available within pip, or do all python libraries used in VS have to have been pre-compiled for Windows?

Thanks in advance for any help!

Can pip be used with Python Tools in Visual Studio?

I&#39;m currently working on a C# project and VisualAssist generates these fancy `/// &lt;summary&gt;&lt;/summary&gt;` comments for me and I&#39;ve been using them do document my code.

I assume there must be a way to use these comments to create HTML documentation like those done by Doxygen or Javadoc. How do I do that?

Setup: Entity framework code first to new database.

Scenario: I&#39;m playing around with EF and I add a bunch of elements to my database. I then change the entity model, and while I know that I could do migrations, I just want to start from scratch and basically wipe the database from the earth.

The database used by default was (localdb)\v11.0.

My question is:

Can I go somewhere and just delete a file, or start some kind of manager to delete that database and start from scratch?

For as long as I can recall, Visual Studio has had an integrate dialog that allows you to easily organize the tab order of your controls.

I&#39;ve just created my first VS 2012 WinForms project, added all of my controls and went to find the Tab Indexing dialog, and it appears to be missing from Visual Studio.

I found [this MSDN article][1] which states that I can open this dialog by going to FORMAT&gt;Tab order.  The problem is that there is no Tab Order option on my FORMAT menu.  Alternatively, the documentation states th at Ctrl+D should open this dialog.  It doesn&#39;t.

Another alternative is to select the VIEW&gt;Tab Order menu option.  This method causes Tab Index boxes to hover over your controls.  You can subsequently click on your controls, one at a time, in the order in which you want them to tab, to set the tab order.

This isn&#39;t acceptable because my form contains numerous panels and group boxes that cover one another.  It is impossible for me to click-through my controls because many of them are no longer visible in the designer.

Is there an easy way for me to setup the tab order of my controls like there previously use to be within older versions of Visual Studio?

Unresolved external symbol LNK2019

I defined a special file: `config.h`

My project also has files:

    t.c, t.h
    pp.c, pp.h
    b.c b.h
    l.cpp

and #includes:

**in t.c:**

	
        #include &quot;t.h&quot;
    	#include &quot;b.h&quot;
    	#include &quot;pp.h&quot;
        #include &quot;config.h&quot;
	
**in b.c:**	

        #include &quot;b.h&quot;
    	#include &quot;pp.h&quot;
	
**in pp.c:**

        #include &quot;pp.h&quot;
    	#include &quot;config.h&quot;
	
**in l.cpp:**

    	#include &quot;pp.h&quot;
    	#include &quot;t.h&quot;
    	#include &quot;config.h&quot;
	
there are no include directives in my `*.h` files, only in `*.c` files. I defined this in config.h:

    const char *names[i] =
            {
                &quot;brian&quot;, &quot;stefan&quot;, &quot;steve&quot;
            };
        
and need that array in l.cpp, t.c, pp.c but Im getting this error:

    pp.o:(.data+0x0): multiple definition of `names&#39;
    l.o:(.data+0x0): first defined here
    t.o:(.data+0x0): multiple definition of `names&#39;
    l.o:(.data+0x0): first defined here
    collect2: ld returned 1 exit status
    make: *** [link] Error 1

I have include guards in every `*.h` file I use in my project. Any help solving this?

When I try running my Xcode Project it fails with an error stating that I have duplicate symbols. I looked online where the find these duplicates but have had no luck:

Any ideas how to fix this? 

Duplicate Symbols for Architecture arm64

I simply want to rid of the warnings that pop up like these:

    ld: warning: directory not found for option &#39;-F/Users/m/Desktop/FacebookSDK&#39;
    ld: warning: directory not found for option &#39;-F/Users/m/Desktop/FacebookSDK/FBAudienceNetwork&#39;
    ld: warning: directory not found for option &#39;-F/Users/gavin/Downloads/shaffiulla11-bat-b86d81d8adc6&#39;
    ld: warning: directory not found for option &#39;-F/Users/gavin/Desktop/shaffiulla11-bat-b86d81d8adc6&#39;
    ld: warning: ignoring file /Users/Gavin/Desktop/FacebookSDK/Bolts.framework/Bolts, missing required architecture x86_64 in file /Users/Gavin/Desktop/FacebookSDK/Bolts.framework/Bolts (2 slices)

Obviously I am using different directories now because of multiple reformats of my drive because of Logic Board issues and just would like to know the most convenient way I can get rid of these errors. Thanks for the time and help.
