Re: access specifiers

private which is the default, means the members are not accessible outside the class.
protected means that members are not accessible outside the class, except the derived classes.
public member are anywhere accessible outside the class.

Re: Two modes to include header files

admin — Sun, 06 Dec 2009 00:04:56 +0530

When using "", compiler looks for the file starting from the current directory of the source file, while when <> are used, compiler directly starts with the include folder.

So for standard header include files we should use <> rather than "". This would improve compile time

Yes, its allowed. here is the syntax:

int a[] ={1,2,3};
int (&ref)[5] =a;

Global static variables and class level static variables: On program start-up
local static variables: When control reaches the block initializing them

Re: Array of references

References are not objects. Array requires its members to be directly accessible by knowing its address.

Because a reference can't be reseated it has to be initialized with some value. We can't have an array of references because we can't give objects at the time of creation of such an array. There is no such C++ syntax.

C++ Standard 8.3.2/4:

There shall be no references to references, no arrays of references, and no pointers to references.

I don't want to or doesn't have a compiler installed on my machine. Is there any web based compiler that can compile my code?

Re: template specialization

Vikas — Sat, 05 Dec 2009 22:25:04 +0530

template specialization means to override the default template implementation for a particular type. This is also called full specialization.

For Example we specialize for a particular type, float.

In partial specialization, we do override the default implementation, but leave the template user with a template type to instantiate with. For example we might partially specialize for pointer to a type(T *)
