Do arrays have pointers C++?
C++ separates the issue of allocating an array from the issue of using an array. Once you have an array, what you actually have is a pointer to the first thing in the array. C++ does not distinguish between a pointer to one variable and a pointer to a whole array of variables!
How do you declare a pointer to an array in C++?
Let’s understand through an example.
- using namespace std;
- int main()
- int ptr1; // integer array declaration.
- int *ptr2; // integer array of pointer declaration.
- std::cout << “Enter five numbers :” << std::endl;
- for(int i=0;i<5;i++)
