Thank you. I'm already using it.😊
You are welcome.

Sir, I use Visual Studio for many purposes.
And I had install qt creator but I couldn't understand how to setup it.
you need to choose both compiler and toolkit when you install qt
Anonymous
I use Qt Creator (due it is cross platform, and ease of use)
however, VS is more recommended for windows
Sometimes I use qt creator too.

They are both very good.

Will I have to reinstall qt creator for setup correctly?
M.Khorram
have installed in from online repository?
(I install the offline version)

Yes I installed it online

From where can I get the offline version??

hey guys, I declared an array and a pointer globaly
now I can assign the address of the array like below when I do it Under main() :
ptr = array ;
but if I want to do that assignment globaly too, I should do it this way :
int * ptr = array ;
what's the reason ?

you need not to install offline version. I did that because I was trying to install it for several times. you should install only a few things

Sir please tell me how Can I get the offline version. On qt site there is no any option to download the offline version.🙏

I'll keep it in mind 😊.
you can google "qt offline installer", the first result would be this one:

note that you don't need offline installer until you don't need to install it multiple times

I can but have to do it like this :
int * ptr = array ;
take a look at the code below :
#define SIZE 4
int arra[SIZE] = {1,2,3,4} ;
int arrb[SIZE] = {5,6,7,8} ;
int * pta =arra ; // assining arra's address to pointer
int * ptb;
int main(){
ptb = arrb ; //assining arrb's address to pointer
int i;
for ( i = 0; i < SIZE ;i++)
{
printf("%d\n",pta[i]);
}
for ( i = 0; i < SIZE ;i++)
{
printf("%d\n",ptb[i]);
}

aha , got it 👌👍
thanks alot 🙏

Hello, I'm googling for some document that speaks about "mixing standard c++ parallel algorithms with qt5 gui", please can anybody address (help to find, give a link) me?
Anonymous
Do anybody know about mixing standard c++ algorithms and qt5 gui?
Anonymous
using standard c++ parallel algoritms in a code with gui application without blocking the gui that can run with the main thread... I'm looking for some guide, but without success
Anonymous
I likec++ standard algorithms but how use them with Qt?
Anonymous
yes but, I'm using standard containers, this is not a problem
Anonymous
the problem is run a parallel algorithms from a gui application in qt

for example

could you give link for std parallel algorithms c++&

👍 yes, if I try to have some feedback to update for example a progress bar, the gui results blocked. And I was looking for some document that describe in general what to do in similar cases
Alex

this is not parallel algorithm. for gui you need one thread to handle gui input and another one for processing
Anonymous
why not? I can update a progress bar in a main thread from a parallel for_each (multiple thread), it could be view in similar manner to update a vector values with a for_each
Alex
you should not block main thread, cause application will be freezed
Anonymous
yes, that's the problems, I'm looking to perform this in safe way? but, 🙁 without success
Alex

just create another thread
Anonymous
mmm, and pass to this thread, for example a lambda with a parallel for_each?
Alex
pass progress bar, or what do you need to update. do not forget to protect shared vars with mutex
Alex
or even do not pass gui elements, do staff in thread and then use QT signal to update gui element

Print increasing number of spaces, followed by alternating _ and |, followed by newline character
Or you divide the screen into x and y coordinates and perform some checks in a for loop.
V01D
Which would look nicer than print print print print

Thanks bro!
I liked atom's interface and also it is easy to use text editor.😊🤗
But in ides I found code blocks more easy to use for c & c++ and NetBeans helps in Java.
BTW I'm windows user can you please suggest me some other ide for c & c++.
If you're on windows you can also try Microsoft's Visual Studio (not vscode) and Dev C++, both free

Dev C++ is outdated af.
Never use it, if you encounter errors no one will help
