Cannot use .begin() or .end() on an array

Question

The error reads:

request for member \'begin\', \'end\' in \'arr\' which is non class type int[5], unable to deduce from expression error.

Answer 1

In C++, arrays are not classes and therefore do not have any member methods. They do behave like pointers in some contexts. You can take advantage of this by modifying your code:

#include 
using namespace std;

int main()
{
    int * mypointer;

    const int SIZE = 5;
    int arr[SIZE] = {1,3,5,7,9};

    mypointer = arr;

    for(auto it = arr; it != arr + SIZE; ++it) {
        cout<<*mypointer<

Of course, this means that mypointer and it both contain the same address, so you don't need both of them.
