Which of the following gives the memory address of the first element in
array aFoo, an array with 100 elements?

A) aFoo[0];
B) aFoo;
C) &aFoo;
D) aFoo[1];

When I run this program option B and C both give same answer, so which one is correct

Thanks a lot for your replies

7
8
9
10
11

#include <array>
#include <iostream>

int main(void)
{
    int aFoo[100];
    std::array<int, 100> arFoo;
    std::cout << std::hex << aFoo << "\n";
    std::cout << std::hex << &(aFoo[0]) << "\n";
    std::cout << std::hex << &(arFoo[0]) << "\n";
    std::cout << std::hex << arFoo.begin() << "\n";
    std::cout << std::hex << arFoo.data() << "\n";
    return (0);
}
Edit & run on cpp.sh
