When do you start learning data structures and algorithms?

i am new to C++... ai using codeblocks...but it doesn't seem to recognise the #include <iostream> or #include <iostream.h> directives....is it an issue that can be resolved or i just switch to another IDE?

Did you save it as cpp file ?

Amit

Thanks

Amit

Any one have a problem in programming i can help him 😁

I'm a noob plz help me

Ok

Can i ask? I understand this question but how write source code.

Can i show question?

this method makes sure that newly entered element is always at the front of 'q1' so that pop operation just dequeues from 'q1','q2' is used to put every new element at front of 'q1' push(s,x) // x is the element to be pushed and s is stack 1) Enqueue x to q2 2)One by one dequeue everything from q1 and enqueue to q2 3)swap the naes of q1 and q2 //swapping of naes is done to avoid one more movement of all elements //from q2 to q1 pop(s) 1) Dequeue an item from q1 and return it

Did you save it as cpp file ?

Yeah...all rules are clearly followed...but CODEBLOCKS i dentifies the preprocessors directives as errors

Why not use the compiler and figure it out by yourself? It's not that difficult at all

klimi

I think this is easy without any advanced knowledge

How the "this" keyword works?

BinaryByter

How the "this" keyword works?

the member function gets a "this" pointer as the first argument, after compilation

BinaryByter

Or the nth argument, really

BinaryByter

Can be implemented in many ways

Vikram

Can be implemented in many ways

In this way"This->"?

Hello guys I have a problem -static assertion failed: std::atomic requires a trivially copyable type

Silvestr

What I should to do that my type can be trivially copyable?

Silvestr

so if I have custom constructor that means my type isn't trivially copyable?

BinaryByter

What I should to do that my type can be trivially copyable?

remove the constructor

BinaryByter

so if I have custom constructor that means my type isn't trivially copyable?

Yes

Silvestr

remove the constructor

also copy and move constructor?

BinaryByter

Probably not

Silvestr

Probably not

#include <iostream> #include <atomic> #include <string> struct Copy { std::string name; std::string surname; }; int main() { std::atomic<Copy> copy; return 0; }

Silvestr

even for this I receive assert

Silvestr

from my investigation result is next -> if you have custom constructor or move or copy constructor, also if types that you include in your class also have constructor - this is not trivially copyable type

BinaryByter

even for this I receive assert

is string trivially copyable?

Silvestr

is string trivially copyable?

I think no because it have another constructors

BinaryByter

yes

Silvestr

yes

std::cout << std::is_trivially_copyable<std::string>::value;

Silvestr

this is print 0

BinaryByter

yes

Silvestr

thank you all for help.

It does write a newline

Mihail

It's just that you're expecting to have an empty line

Mihail

And for that you need one to end the current line and one to skip a line

Mihail

Or is your output different?

Thanks for answer. But why in other cases one endl is enough to break a line?
