Thanks Laserlight, you are rite

I was just going through Cocoa (Objective C's framework) and saw the method alloc which was inherited from the base class (NSObject) and seemed it was something...

Hi,

In the below example, inside the implementation of the static function f1 is there a way to determine whether A::f1() or B::f1() invoked f1 ?



class A
{
public:
static A*...

Yes GCDEF is correct.

Just thought i would add some points (correct me if i am wrong):
1) C-Strings

C-Strings are treated as an array of characters ending with a null character '\0'
C-String...

Thanks Skizmo and Philip, I am just a bit confused with definition vs initialization.

The reason I am confused is that because the below mentioned program compiles successfully (a1 is not defined...

Thanks superbonzo for clarifying that

Thanks Nuzzle, I suppose it is better to treat it as a feature of C++ since i am not fully aware of what goes behind the scene.

Hi,

My understanding was that all static data members in a class needs to be initialized.

In one of the programs, I forgot to initialize a static composite data member (what i mean by composite...

As per my understanding (correct me if i am wrong):

1) Yes B inherits A, but display() is a function that belongs to A and is only inherited by B.

It was possible for A::display() to invoke...

Laserlight - Yes you are correct, my 2nd example follows LSP.

I found it interesting that B::f1() could be accessed outside of class B. In this case class A::display() (base class function)...

Thanks Nuzzle and Laserlight

Just to summarize the reason how this happened:
1) Access is checked by the compiler at compile time, the fact that it is A::f1() public allows the compiler to let it...

Thanks Laserlight, I agree that the design doesn't follow the Liskov substitution principle.

However my question is:
B::f1() is private and shouldn't be accessible outside the class B, however i...

As per my understanding (I could be completely wrong, so feel to correct me)
- BaseClass is used by multiple teams.
- you want to use the same BaseClass but want to use it DerivedUtil instead of...

Hi,

A is the base class
B is the derived from class A

A has a public virtual function f1()
B has a private virtual function f1()

B::f1() not accessible using an object of class B however...

Thank you so much !! I was breaking my head over it for a long time...

Hi,

I am trying to create a function pointer to std::endl

I get a compilation error in line number 36, where I am trying to assign the function pointer of std::endl to a pointer variable.
...

Thanks a lot !!

Just feel timeb might be compiler specific (I could be completely wrong)

We are working on mac and windows... so i thought it would be better to use boost library (posix time)....

Thanks

Thanks a lot !!

gmtime actually resolves the problem because it is the GMT time

I did check timezone, tzname[0], tzname[1], it doesn't show the correct names, but thats...

Thanks a ton !! I wouldn't have guessed that in my dreams !!

Windows shows it as 8....

Strange it actually needs to be 8hrs .... :) not sure why it is 7:30 ... though the timezone is properly...

Hi,

I have a doubt regarding time_t

I am initializing a time_t variable to 0.
When I display it, it shows "Thu Jan 1 07:30:00 1970" ?
I expected it to Thu Jan 1 00:0:00 1970 since t1 was...

Hi,

I am a newbie to boost graph library (BGL).

1) To build a graph with vertices with unique ids - Able to do this
2) To get the vertex containing a specific idsI have created a graph with...

Thanks a ton !!

Will go through them and come back with the doubts that I have.

Thanks again all of you !!

Hi,

I am looking for a Library / function / formula to check if a point is inside a polygon.

Assuming the polygon has N sides, and the co-ordinates are given of each vertex is given.
Also the...

Thank you so much for all your replies.

I had this vague view that there was a function called "any" ... hahah .. I was so wrong.

I suppose std :: find would suit my needs.

Thanks all

Hi

I wanted to know if there was a way to check if a variable was inside a set of values.

Like in the below given example, I want to know if n1 is either 5, 8, 27 or 2567
Is there a better way...

Thanks a lot Codeplug, will read through that article and come back.

Yeah I wish boost had more detailed documentation on how and in what situations to use them.

Thanks again,
Muthu
