Is your output different from mine?
no

Thanks for answer. But why in other cases one endl is enough to break a line?
Because print_map already adds one
Mihail
And you add another (which leaves an empty line)
Elnee
Oh... really
Elnee
I'm sorry that was easy
Mihail
No problem
Elnee
Thank you :)

Try searching on gen library

hi. im wanna asking , can we put a passing by reference parameter with an array ??

When passing an array (T[]) as parameter it basically decays to a pointer to the type of the array (T*). So changes made to the array are visible from the calling function

How to find all adjacent Element of matrix I searched on Google but I am only able to find only adjacents of Element which is center of matrix but I also want to find adjacents of core side Element of given matrix???

Hello all) howI can cast from rvalue to lvalue?
Silvestr
maybe some std:: func?
Liam
maybe any other way to do it)?
Please consider to express your original problem? Casting rvalue to lvalue is somewhat strange.

In class I have copy and move constructor, but I assign it from function something like this object = myFunc(); And in this situation is called move costructor but I need copy
MrSmith
Hi guess I need C code which write 1960-1970
MrSmith
It good if it have many goto
MrSmith
A meen I try dig old code between this years with many goto
Silvestr
A meen I try dig old code between this years with many goto
goto is fast) its just asm jump
MrSmith
Please no holywars I just need cod
Silvestr
but it creates a lot of bus if you don't completely undertand what you do

enjoy
Silvestr
So what about casting to lvalue without creation separate var?
MrSmith
So it is very new code

I'm not quite understand why you need copy constructor here. And for your codes, it won't call a copy/move constructor, sinc RVO will optimize the unecessary copy/move.

I need copy of this object) I can create method for that but ...
Liam
In this situation, RVO erase the unecessary copy. It just won't happen.

Try this:
#include <iostream>
struct Foo {
int member = 0;
Foo() {
std::cout << "Foo::Foo().\n";
}
explicit Foo(int m) : member(m) {
std::cout << "Foo::Foo(int).\n";
}
Foo(const Foo& foo) : member(foo.member) {
std::cout << "Foo::Foo(const Foo&).\n";
}
Foo(Foo&& foo) : member(foo.member) {
foo.member = 0;
std::cout << "Foo::Foo(Foo&&).\n";
}
Foo& operator=(const Foo& foo) {
member = foo.member;
std::cout << "Foo::operator=(const Foo&).\n";
return *this;
}
Foo& operator=(Foo&& foo) {
member = foo.member;
foo.member = 0;
std::cout << "Foo::operator=(Foo&&).\n";
return *this;
}
};
Foo func(int m) {
return Foo(m);
}
int main() {
Foo foo = func(42);
return 0;
}
Liam
Result:
$ ./a.out
Foo::Foo(int).
Liam
If you just wanna see the calling of copy constructor, you could write something like this:
Foo foo = func(42);
Foo foo_ = foo;
Foo foo__(foo);
But in real-world-codes, it's useless.
