I do use -Wall but for release code only, thank you for a tip.

I see, thank you.

Hello,

Implicit default ctor does not initialize the built-in data members, so what is it needed for?

Thanks.

Ok, I see, thank you.

I know how it's calculated: e.g. (-1 modulo 256) + 256 = 255, I am wondering about the internals.

Btw, "C++11 Clause 4.7 - Integral conversions" is it from the C++ standard? Where can I get?

Thanks.

Hello,

So, the

unsigned char c = -1; // c has value 255

Why is that, on a bit level? Negative sign would set the highest bit to 1, and 1 would set the lowest bit to 1: 10000001 which is...

Thanks for replies.

Hello,

const_cast<> supposed to "cast away const" but it does not. The output is: 1002 1001, I expect it to be 1002 1002. Could someone explain what's going on? Thx.



#include<iostream>...

I see, thanks guys for all responses.

Hello,



int arr[10];
int* p = arr;
int (*p2)[10] = &arr;


So, pointer p is a pointer to an array, I can use it to access elements of arr as in *(p+5).

Thanks for your help.

Because it looks like my object is located beyond the memory that I actually have.

I think it's just not showing two leading zeros in 0x7fff0d065098.

Also, 0x7fff0d065098 is 140,733,411,905,688 decimal, which is 140 Terabyte, 733 MB, and so on. I have only 8GB of RAM on my laptop, how is that possible?

Right, it shows 8.

I am not looking for the size of the pointer or reference, but, let's say, I want to know the address where my object is stored.

Hello,

My code:



int i12 = 1001;
cout << i12 << " " << &i12 << endl;

My FIFO is a class, it is the producer and consumer applications use select() to monitor sockets and stdin besides the FIFO so the loop is quite involved.

Anyways, select() is not supposed to...

Hello,

I have a producer application that writes data into a FIFO, and I have a consumer application that reads data from FIFO utilizing select() and read() functions inside of a while(true) loop....

> If you know in advance that the string will become very long, it could make sense to call "reserve" upfront. This way there will be less memory reallocations during the string building process. But...

That's the way I did it but I need to build long strings from pieces so I had to declare several variables.

-- thank you.

Hello,

Why it's not working and how to make it work?



string str = "hello" + " *** ";


Thank you.

Creating threads is not difficult at all, it takes only a few lines of code - find some samples. Parallelizing your code to run on those threads would be challenging - google for it, I bet you'll...

Right, there was an error EEXIST when I was creating FIFO b/c that FIFO already existed.

Thanks again for your help.
