Operator Associativity

• Each operator has a default associativity
• Associativity of operator + is LR

sum = x + y + z;    
sum = (x + y) + z;  // statement meaning identical to first

• Associativity of operator = is RL

a = b = c;    // valid statement
a = (b = c);  // identical meaning

• Except for assignment operator=, binary operators associate LR
