make parsing and semantic analysis simpler.

improve error recovery and error reporting.

increase the chances of reusing the machine-independent code optimizer in other compilers.

improve the register allocation.

In statically typed languages, each variable in a program has a fixed type

In un-typed languages, values do not have any types

In dynamically typed languages, variables have no types

In all statically typed languages, each variable in a program is associated with values of only a single type during the execution of the program

Both $$' \oplus '$$and $$'*'$$ is left associative

$$' \oplus '$$ is right associative while $$'*'$$ is left associative

None of the above
