More Complicated Assignments

1. Multiple targets (PL/I)

• A, B = 10

2. Conditional targets (C, C++, and Java)

• (first = true) ? total : subtotal = 0

3. Compound assignment operators (C, C++, and Java)

• sum += next;

4. Unary assignment operators (C, C++, and Java)

• a++;

• C, C++, and Java treat = as an arithmetic binary operator

• a = b * (c = d * 2 + 1) + 1

• This is inherited from ALGOL 68
