Although Java has the rule that the left operand of every binary operator is evaluated before the right operand, most languages give the compiler the freedom to choose which operand is evaluated first. When expressions have side effects, the value of the expression can be different depending upon which order is used.
1. Give an example in C++ of an expression whose value depends upon the evaluation order.
2. Show the orders that produce different values and the values they produce.
3. Explain what side effect is the expression contains.
