How can i change the interpretation of a variable.

cout<<<code>hex</code><<123233;//displays in hexadecimal format.
cout<<<code>oct</code><<121223;//displays in octal format.
cout<<<code>dec</code><<12323;//displays in decimal format.

As far as I understood, there is no need of using ASSERT, as you can use VERIFY, because it works both in Debug and Release builds and ASSERT does not work in debug builds

int i;
ASSERT( (i=GetI()) != 0 );

int i;
VERIFY( (i=GetI()) != 0 );
