int array[3]{1,2,3}; int (*ptr)[3]=&array; When dereferencing std::cout<<*ptr; (или std::cout<<ptr[0]) по ... address of the next element. Or does the array break up in std::cout<<ptr[0];, but not in std::cout<<ptr[0]+1;?

The question will probably seem simple, but not for me. The size is unknown in advance, it all depends on the user's desire. ... w much will need to be added, everything is decided in prime time. Or is everything solved by declaring struct Book** books?

The class creates a structure and a pointer to it. In the constructor, the necessary memory is allocated for the structure. A ... the structure. How do I do this correctly using the free () function ? if (pData) free(pData->matrix); // это не работает

I am writing a joke program that will change the image of the desktop: An error occurred in one of the lines of code: System ... wears that it is impossible to convert const char* to PVOID. I think I missed something somewhere. What could be the problem?

Is there any difference in performance, or are there any Pros and Cons to using such a design at all: Type* a = new Type(); ... be stored / processed roughly as a reference to at a lower level? I will be grateful for your explanations in this matter.

Why the find() method uses a pointer. That is, in this example #include <iostream> // std::cout #include <algori ... ay. We just need to search for it in the array and that's it. Why can't this be done without a pointer? Thank you in advance!

Please explain why this code works: cout << "Test: "; char *tmp; cin>>tmp; cout << "Test: " << tmp << std::endl;

I need to display an array with a size of about 1000x1000 . If you constantly access the array elements via [] [], it takes a ... ointers. It should also be faster. What is the best way to run through such an array with the shortest time through pointers?

Reading the book by Brian Kernighan on the C programming language, I liked the example of implementing the strcpy function, b ... t, "Hello world"); } Please explain in simple words. You can also give a comment on the first method, thank you in advance!

What is the fundamental difference between a reference and a pointer in C++? When is it better to use a reference, and when is a pointer? What are the limitations of the former, and what are the latter?

The exam asked a question: Why can't I stack pointers? The difference between pointers returns the number of elements betwe ... should return a certain number, but it turned out that the addition of pointers is not defined. I'm interested in the reason.

I'm trying to figure out the pointers. It seems like I started to understand them, but after these two simple functions and t ... 1, &c2); swap(&c1, &c2); printf("c1 = %d, c2 = %d\n", c1, c2); return 0; } Result: с1 = 2, с2 = 1

Please tell me what role the ampersand plays in the parameter of this function because the program works correctly both with ... summands_it) { cout << *summands_it << (summands_it != summands.end() - 1 ? " + " : "\n"); } }

I often see this construction: int ** p; I understand that this is a pointer to a pointer. Why is such duality necessary and where is it applied?

Hello. Are there any significant differences between such pointer definitions: int* a; int *b; I would also like to find ou ... void this: int var = 123; int *ptrvar = &var; int **ptr_ptrvar = &ptrvar; int ***ptr_ptr_ptrvar = &ptr_ptrvar;

I have a poor understanding of how smart pointers (especially shared_ptr) interact with polymorphic types. The overall pictur ... // ... } } int main() { shared_ptr<Base> base = make_shared<Derived>(); do_something(base); }

I do not understand why, for example, to output a pointer to int, it first needs to be dereferenced, and when using a pointer ... же находится сама строка // хотя, я думал, что здесь должен был бы выводиться адрес первого символа строки. cout << c;
