What is the difference between the address stored and displayed in C and C++?

In C, if I make a variable and print its address like this:

int a;
int main (void) {
    printf ("%p", &a);
    return 0;
}

The output was: 00AA

The same program in C++ using the line:

cout << &a << endl;

The output was: 0x8f970aa

What is the difference between these two?

I compiled both the programs using Turbo C.
