error: no matching function for call to 'begin(int*&)' c++

Question

#include <iostream>
#include <iterator>
using namespace std;
void print(int ia[])
{
    int *p = begin(ia);
    while(p != end(ia))
        cout<<*p++<<'';
}

int main()
{
    int ia[] = {1,2,3,4},i;
    print(ia);

    return 0;
}

P pointer to the first element in ia. why it said"error: no matching function for call to 'begin(int*&)' c++" thanks!:)

Answer 1

Because inside print(), the variable ia is a pointer, not an array. It doesn't make sense to call begin() on a pointer.
