What is the difference between '++i' and 'i++' in C++?

'++i' increments the value of 'i' and then returns it, while 'i++' returns the value of 'i' and then increments it.

'++i' increments the value of 'i' after it's used in an expression, while 'i++' increments 'i' before it's used.

'++i' and 'i++' are the same and can be used interchangeably in C++.

'++i' and 'i++' are invalid expressions in C++.

What is the difference between 'public', 'private', and 'protected' access specifiers in C++?

'public' members can be accessed by any function, 'private' members can only be accessed by member functions of the same class, and 'protected' members can be accessed by member functions of derived classes.

'public' members can only be accessed by member functions of the same class, 'private' members can be accessed by any function, and 'protected' members can be accessed by member functions of derived classes.

'public' members can be accessed by any function, 'private' members can be accessed by member functions of the same class, and 'protected' members can only be accessed by member functions of derived classes.

'public', 'private', and 'protected' are all synonyms in C++.
