1. Properties of a C++ variable

Consider:

int main( )
{
    // Local variables:
    int x = 5;
    double d = 0.1;

    // Variable sizes:
    int x_bytes = sizeof( x );
    int d_bytes = sizeof( d );

    // What about variable addresses ?
    int x_addr = addressof( x );
    int d_addr = addressof( d );

    return 0;
}

Note: this sample will not yet compile because of the addressof.

What do we know about x and d?

• Types are int and double

• Operator sizeof returns sizes in bytes

• How about an address of a variable?
