- A keyword can't be used as variable name.
- An expression may contain any sequence of constants, variables, and operators.
- When there are two or more operators with same priority in an expression then their order of evaluation is decided by the associativity.
- Left-to-right (L-R) associativity means that the left operand of operator must be unambiguous.
- Right-to-left (R-L) associativity means that the right operand of operator must be un ambiguous.
