The second code snippet from the Unary section does not illustrate the core difference between the pre and post increment operators well (++i vs i++): int i = 3; i++; // prints "i = 4" ...

// Pre-increment : In pre-increment, first value is incremented by 1 and then it is assigned. // Post-increment : In post-increment, first value is assigned and then it is incremented by 1.
