QUESTION
Mostly all things explained by fredoverflow(user 237K Rep.) in his Two answers
But while implementing Move constructor and overloaded Move Assignment operator(OMAO
)( I am using these short form throughout the question ) I am facing some problem that I will put here.
Also there is another answer by user Greg Hewgill (user with 826K Rep.)
https://stackoverflow.com/a/3106136/11862989his
I am Quoting him,
Suppose you have a function that returns a substantial object then an ordinary C++ compiler will create a temporary object for the result of multiply(), call the copy constructor to initialize r, and then destruct the temporary return value. Move semantics in C++0x allow the "move constructor" to be called to initialize r by copying its contents, and then discard the temporary value without having to destruct it.
I will also refer this in question.
okay Now I will start
Code .cpp ...ANSWER
Answered 2021-Jun-03 at 03:541_main: Move constructor is not executed due to copy elision The extra destructor is observed after the swap is done, the temporary object is destroyed.
2_main: Same observation as in 1_main where move operator is called
3_main: The error is seen because you're using a low version of compiler. might need to specify -std=c++11
4: a.s=nullptr
is not a case of move as you're allocating new memories and do kind of copy. For example

QUESTION
I am trying to update the number of people in the code below by adding one every time an instance of the class is performed, it used to work for me but I tried the code today and it isn't working. Also when i try and print the "User.people" variable it returns what I assume is its address in the memory. Please help me.
...ANSWER
Answered 2021-May-22 at 06:32Your error is that you gave the same name to two different class attributes: first, the simple variable; later you redefined people
as an instance method. By the time you try to alter the population count, people
is redefined as a method, so the increment is illegal. Simply change one name:

as JSON.
When the page loads, parse the JSON, and then update the values of all the selects from the array.
QUESTION
I am trying to transform a table of data--I want the rows to become the columns, and the columns to become the rows (like a total complete pivot). I am using the method from this answer to do so.
If it makes any difference, I am running my own SQL server on a Raspberry Pi using PHPMyAdmin.
The table (truncated) looks like this:

Answered 2021-May-05 at 20:13You seem to be suggesting that Grant
