[Solved] Why destructor is being called but construction not being called when passing object as a parameter? [closed]

by

[ad_1] Passing an instance of a class by value invokes the copy constructor.

[Solved] How to form a dynamic array in C++?

by

[ad_1] Use std::vector, which is designed for exactly this use case. The (rough) translation of the Perl code you have given to C++ using std::vector would be something like this: #include <iostream> #include <vector> int main() { // Declare a vector that can only contain int values. std::vector<int> numbers; // Put the numbers [1,10] into … Read more

[Solved] Why can’t I get the index of a jQuery object?

by

[ad_1] I don’t think map() is giving you want you want. Since you want to filter element from an array it’s easier to use filter() instead of map(). function $errorObjectFunction() { return $(“div[id^=name]”).filter(function() { return ($(this).find(“:first-child”).hasClass(“error”) == true || $(this).find(“.field_error”).length > 0) }); } var $self = $(“#self”); var jdks = $errorObjectFunction(); var hdjs = … Read more
