template<class....>

in my class it is intended, so you can reconstruct it at any time

template<class....>

It's more preferable,you overload new and delete operator themselves

So? I don't know why you call it this way, but it's wrong term

It's more cleaner, when one use std::tuple what do you think

Try using char *argv[] or char **argv, it might not be the problem but worth trying.

No, it's not

It's more cleaner, when one use std::tuple what do you think

I don't think you know what you're talking about

Hmmmm ok

hmm, how would I fix this the right way?

template<typename T> class AutoPtr { T *elem; public: template<class... Args> AutoPtr(Args... args) { elem = new T(args...); } ~AutoPtr() { delete elem; } inline T& operator *() { return *elem; } void reset() { delete elem; elem = new T; } }; Does this look like fully valid C++ code to you? It feels like something is wrong but I can't tell what. It compiles tho

Does anyone know how to fix exc_bad_access?

How will copy assignment work in this class?

e.g. AutoPtr<int> X { 3 }; std::cout << *X; *X = 123; std::cout << *X;

template<typename T> class AutoPtr { T *elem; public: template<class... Args> AutoPtr(Args... args) { elem = new T(args...); } ~AutoPtr() { delete elem; } inline T& operator *() { return *elem; } void reset() { delete elem; elem = new T; } }; Does this look like fully valid C++ code to you? It feels like something is wrong but I can't tell what. It compiles tho

I mean, what will happen when we have X = Y and both are AutoPtr?

the assignment is 'fine' - as just mentioned, there will be a double free which is UB and will most likely crash

template<typename T> class AutoPtr { T *elem; public: template<class... Args> AutoPtr(Args... args) { elem = new T(args...); } ~AutoPtr() { delete elem; } inline T& operator *() { return *elem; } void reset() { delete elem; elem = new T; } }; Does this look like fully valid C++ code to you? It feels like something is wrong but I can't tell what. It compiles tho

template<typename T> class AutoPtr { T *elem; public: template<class... Args> AutoPtr(Args... args) { elem = new T(args...); } ~AutoPtr() { delete elem; } inline T& operator *() { return *elem; } void reset() { delete elem; elem = new T; } }; Does this look like fully valid C++ code to you? It feels like something is wrong but I can't tell what. It compiles tho

What happens when T doesn't have default constructor?

There will be a compiler error when a user will try to call reset

Yes, and that makes many classes unusable with this implementation. unique_ptr doesn't have this limitation

Hi is anyone doing iq option

Salve

Is there any method to iterate a number or integer for ex if i want to iterate through 45397 to check every digit as odd or even how to do this??

int n = 45397; while (n != 0) { int digit = n %10; n /= 10; }

thanks sir

#include <iostream> using namespace std; int main() { int a = 10; int *p = &a; int **q = &p; int b = 20; *q = &b; (*p)++; cout<<a<<" "<<b<<endl; return 0; }

Can someone explain how the output is '10 21' and not '11 20'

Making a chess engine any one help me or join the project?

Is everyone here a student?

Hello guys. Please does anyone have an idea how to write to a file with in a column form. The problem is that it's a loop and contents change after every iteration so I can't write to it with something like this "file << first iteration << second iteration << ..." And again the loop iteration is dynamic so I can't do a row major calculations to print it too. Any help?

I have a vector of arrays. Each array should represents a column. I add to the vector based on the users input. So if the user has for instance 3 arrays pushed into the vector that means each array should be one column. The iteration is fine but writes everything in just one column.

#include <stdio.h> int main () int a=2,b=4; printf ("the value of a is %d\n",a++); printf ("the value of a is %d\n",a++); printf ("the value of b is %d\n"b——); return 0; }

Where is the error?

I think you forgot to put a comma in your last printf statement

Still showing error

After int main
