this is my problem please solwa my problem

I keep getting the following error when trying to compile the code as provided in 16.4MultipleFiles_CompilationModelRevisited: undefined reference to `incr_mult(int, int)' collect2.exe: error: ld returned 1 exit status

I copied the files which should be fine. I cannot find any solution, I tried everything from reinstalling GCC to restarting my pc. Please help

I got this file vc140.pdb instead of filename.exe i tried different kind of solution on the internet but same problem keeps out at every run

This line explanation on Udemy (timestamp => 5.12) regarding this needs to be reviewed

std::bitset<16>(data)

As you are explaining that your integer variable "data" is 16 bits (4 bytes) but it is declared as short so it should be 8 bits (2 bytes)

I know this may not seem a big issue, but people who have just gotten into coding might find this confusing.

The section numbers and headings in the repo don't match the sections in the course syllabus:

https://www.udemy.com/course/the-modern-cpp-20-masterclass/learn/lecture/24458218#content

When we browse the main folder rutura/The-C-20-Masterclass-Source-Code using web browser some subfolders are not sorted correctly. It's good to add additional '0' for folders where number of chapter is less or equal 9
For example instead of "5.OperationsOnData" it would be probably better to have "05.OperationsOnData". Isn't it?

Dear Daniel Gakwaya,

I wanted to thank you for creating this fantastic C++ course and for sharing the code examples on this repository. I have found the material to be very informative and the code examples to be helpful in improving my understanding of C++.

I noticed that there were an error in the comment mentioned below, the returned valued is actually being treated as a reference since the function returns a reference and the result var was declared as a reference also which leads to that action, the mentioned error may fit the second declaration of result which is commented out. I hope this was useful.

Thank you once again for your hard work in creating this course, and I look forward to continuing my learning journey with your guidance.

Best regards,

Hussein Sawan

I noticed when playing with your code that:
if(!(result == true)){ std::cout << number1 << " is NOT less than " << number2 << std::endl; }

and
if(result != true){ std::cout << number1 << " is NOT less than " << number2 << std::endl; }
function the same way. Why use the ! ( ==) notation when just != seems easier to interpet?

Because of this issue , only we get output from the main function, not from the local function. program must be like this ..

#include<bits\stdc++.h>

int global_var1{23};

void some_function()
{
int local_var{10};
std::cout<< " Inside function global_var"<< global_var1<< std::endl;
std::cout<< " Inside function local_var :"<< local_var<< std::endl;
}

void some_other_function()
{
std::cout<< " Inside function global_var"<< global_var1<< std::endl;
//local_var=5;

}

int main ()

{
some_function();
some_other_function();

   std::cout<< " Inside main function global_var" << global_var1<<std::endl;
   
   return 0;

}

I do not want to misinform others, so please correct me if I'm wrong.

First of all, thanks and great credit for the course!
I have a question about course part 13.3.
If this is the wrong place for such questions, delete it.
As an example, it is clearest.
#include

int main(){

const char* p_c_message{"Hello World! Hallo World!"};

/* why is this forbidden 
char* p_c_message{"Hello World! Hello World!"};*/
// but like this, it is ok. Where is the difference
char message1[]{"Hello World! Hello World!"};
char*  p_message1{nullptr};
message1[0] = 'C';
p_message1=message1;
std::cout << "sizeof(message) " <<sizeof(message1) << std::endl;
std::cout << "sizeof(p_message) " <<sizeof(p_message1) << std::endl;
std::cout << "p message; " << p_message1<< std::endl;
std::cout << "sizeof(p const message) " <<sizeof(p_c_message) << std::endl;
std::cout << "p const message; " << p_c_message<< std::endl;
return 0;

}

I noticed that it was said the videos are updated in the commit history, but where to find them, the c++ 31 hours in Youtube?

Line #51 should be:
sandbox_var &= 0b000001100;

some other codes/other websites, I found they don't use "std::". instead, some of them said that "using namespace std" after header filer is replacing this "std::".
is this a good practice to use the "std::" every time?

The project's folder arrangement can be changed so that all of the folders come sequentially, starting from 00, 01...
If you approve, then I can do that by adding a PR. Please let me know what do you think about that.

in pointer arithematic lecture 120 , code line 22 it should be *(p_arr1 +i) but u mistakely did *(p_arr0+i). Kindly correct this sir

I've gotten numerous error's in vs code. What did I do wrong? what do I need to install?
