Operator exercise for first day?

[hageboeck]

Consider this comment by Attila:

The description of vector iterators made me remember that we don't discuss this really in this tutorial. But it may be useful to be aware already at a beginner level. What do you think, what values will b and c take in the following example?

int a = 5;
int b = a++;
int c = ++a;

We may consider playing with this a bit during the first day.

Some things that could be part of this exercise:

• Type promotion
• Operator precendence
• Braces
• Pitfalls with precendence?

x *= 2.; // Promotes to double
x / 2; // might truncate?
