About array in loops

Question

When I write this code :

int apple[5];
for(int x=0; x<5; x++){
apple[x] = 42;
cout<<apple<<endl;
}

I get this :

0x28fed4
0x28fed4
0x28fed4
0x28fed4
0x28fed4

Answer 1

I assume you want to print each element of list apple, for that you need to change your cout statement to
cout<<apple[x]<<endl;
What your program is currently doing is printing the memory location of list apple.

Answer 2

And don't get confuse with char array because << operator treats it differently like this

#include <iostream>

int main()
{
char apple[5];
for (int x = 0; x<5; x++) {
apple[x] = 42;
std::cout << apple << std::endl;
}
}

Output:
